Description

Technical Field

[0001] The present invention relates to a laver filament culture film and a laver filament culture apparatus. More specifically, it mimics the pillar layer, nacreous layer, and lime layer of an oyster shell, and due to its material and structural characteristics, it can culture laver filaments more effectively than a suspended oyster shell bundle, and relates to a laver filament culture film and a laver filament culture apparatus that can be easily utilized as a substitute for a suspended oyster shell bundle.

Background Art

[0002] In the process of general laver cultivation, first, carpospores are collected from mature laver thalli, and after culturing for about 2 to 3 months while adjusting the water temperature and illuminance in a culture container to obtain free-living filaments, these free filaments are transplanted onto oyster shells so that the filaments enter the fine holes formed in the nacreous layer of the oyster shell and the filaments reproduce and sporangia are formed. Then, the oyster shells with formed sporangia at the appropriate seedling collection time are suspended on laver grooves, and by allowing the spores in the sporangia to be released from the oyster shells and adhere to the laver grooves by the tidal current and waves, a series of steps are taken to make the laver thalli grow on the laver grooves.

[0003] In the conventional laver cultivation, the cultivation method of the filaments transplanted onto oyster shells includes a planar cultivation method in which oyster shells are arranged on the bottom surface of a wooden, plastic box or concrete tank and filled with culture water to allow the filaments transplanted onto the oyster shells to reproduce, and a suspended cultivation method in which strings passing through about 10 to 20 oyster shells are arranged side by side on a rod and immersed in a water tank with a depth of about 50 cm to allow the filaments to reproduce.

[0004] Here, there is a research result that the suspended cultivation method is more advantageous than the planar cultivation method in terms of management and economy in that the number of oyster shells that can be cultured is larger and the fresh water volume in the water tank is larger and shows a gentle temperature change compared to the planar cultivation method.

[0006] Nevertheless, conventional suspended cultivation methods have several drawbacks: approximately 400 oyster shells are woven onto a single rod, resulting in heavy weight, high cost, poor lighting due to the shells tipping over and uneven sunlight exposure between the upper and lower shells, requiring frequent repositioning of the shells, wide spacing between rods reducing area efficiency, and the need to ensure a certain level of tank depth and rigidity.

[0007] Therefore, there is a need for a method that can solve the problems of this conventional suspension-type culture method. [Overview of the project] [Problems that the invention aims to solve]

Advantages of the Invention

[0029] The present invention has the following excellent effects. First, in the conventional laver filament culture, as shown in FIG. 1, it was carried out using an oyster shell composed of a lime layer (CL), a nacreous layer (NL) located above the lime layer (CL), and a pillar layer (PL) located above the nacreous layer (NL). However, the laver filament culture film of the present invention is modeled on the pillar layer, nacreous layer, and lime layer of the oyster shell so that filaments are cultured. It is lighter and shows a higher infiltration rate and growth property of laver filaments, can be effectively used as a substitute for oyster shells, and has the advantage that a plurality of bundles of oyster shells can also be substituted according to the size of the film.

[0030] In particular, conventional hanging-type nori filament cultivation methods involved suspending bundles of oyster shells, each tied together, from a rod and immersing them in a deep tank filled with seawater for cultivation. However, the nori filament cultivation apparatus of the present invention has the effect of replacing the multiple bundles of oyster shells that were previously suspended from a rod by using a nori filament cultivation film upright inside the nori filament cultivation housing.

[0031] In this case, compared to multiple bundles of oyster shells suspended from a single rod, the nori filamentous culture film 220 reduces weight to approximately 1 / 13, costs to approximately 1 / 5, and increases area utilization efficiency by approximately 15% or more.

[0032] Furthermore, the seaweed filament culture apparatus of the present invention does not require the use of rods because it does not require the suspension of the film. It is also possible to form the spacing between seaweed filament culture films to be even narrower than the spacing between conventional oyster shell bundles, making it possible to provide a uniform culture environment including uniform lighting, and thereby increasing the productivity of seaweed filament culture.

[0033] Furthermore, the seaweed filament culture apparatus of the present invention allows users to easily adjust the culture environment while visually observing it in real time, and the seaweed filament culture film can be easily fixed and replaced, thereby improving the convenience of cultivation.

[Figure 12] This is a cross-sectional view of a nori filamentous culture apparatus for illustrating the structure and relationship between the nori filamentous culture film and the lighting means. [Modes for carrying out the invention]

[0035] The technical configuration of the present invention will be described in detail below with reference to the preferred embodiments shown in the attached drawings.

[0036] However, the present invention is not limited to these embodiments and may be embodied in other forms. The same reference numerals throughout the specification refer to the same components.

[0037] First, the nori filamentous culture film according to an embodiment of the present invention will be described with reference to Figures 1 to 5, and then the nori filamentous culture apparatus according to an embodiment of the present invention will be described with reference to Figures 6 to 12.

[0038] Figure 1 is a magnified view of an oyster shell to illustrate its structure.

[0039] According to Figure 1, an oyster shell is composed of a limestone layer (CL), a nacreous layer (NL) located above the limestone layer (CL), and a columnar layer (PL) located above the nacreous layer (NL).

[0040] The stomatal layer (PL) of the oyster shell has a dense structure with pores composed of inorganic material, while the nacreous layer (NL) has a relatively loose structure with layers of overlapping calcium carbonate (CaCO3) crystals. Therefore, the filamentous seaweed spores penetrate the nacreous layer (NL) through the pores of the stomatal layer (PL), absorb nutrients in the nacreous layer (NL), and grow.

[0041] On the other hand, the limestone layer (CL) is made of calcareous material, so the filamentous structures of seaweed cannot penetrate it.

[0042] The nori filamentous organism culture film according to the embodiment of the present invention imitates the columnar layer, nacreous layer, and limestone layer of an oyster shell as described above, and provides an environment that is as similar as possible to the morphology of an oyster shell in which nori filamentous organisms can grow.

[0043] Figure 2 shows the structure of the seaweed filamentous culture film of the present invention.

[0044] As shown in Figure 2, the nori filamentous culture film 100 according to the embodiment of the present invention is formed with a triple structure including a base film layer 110, a filamentous growth layer 120, and a filamentous protection layer 130.

[0045] Specifically, the base film layer 110 is a replica of the limestone layer (CL) of the oyster shell 10, serves as a support layer for the film 100, is made of biodegradable material, is flexible, and is transparent or translucent, allowing light to pass through.

[0046] More specifically, it can consist of one or more materials from among PBAT (Poly-Butylene Adipate Terephthalate), PBS (Polybutylene Succinate), PHA (Polyhydroxy alkanoate), PLA (PolyLactic Acid), PCL (Polycaprolactone), cross-linked PVA (Polyvinyl Alcohol), PGA (Polyglycolic acid), modified cellulose, and starch-modified resins.

[0047] Since the base film layer 110 is made of biodegradable material, it can be buried in the ground when discarded, and after being buried, it biodegrades within a few months, thus not causing environmental pollution.

[0048] Furthermore, since the base film layer 110 is flexible, it can be manufactured in a roll shape, offering advantages in manufacturing and handling. Because it is made of a transparent or translucent material, it increases the possibility of light transmission, facilitating microscopic examination.

[0049] The filamentous growth layer 120 is a replica of the nacreous layer (NL) of an oyster shell 10, formed on the upper surface of the base film layer 110, and configured to allow the filamentous nori seaweed to penetrate and grow.

[0050] Furthermore, nutrients that allow the filamentous organisms to grow are added to the filamentous organism growth layer 120, and stomata for the attachment of the filamentous organisms can be formed in the filamentous organism growth layer 120.

[0051] Here, the nutrients may include one or more of the following: agar, pearl, glucose, sugar, yeast, chitosan, hyaluronic acid, vitamin A, vitamin E, vitamin K, calcium carbonate, sodium nitrate, calcium phosphate, potassium phosphate, sodium sulfate, calcium hydroxide, and magnesium hydroxide, and may also include other nutrients not listed hereinafter.

[0052] Nori filamentous organisms that have attached to the stomata of the filamentous growth layer 120 are supplied with nutrients from all sides, resulting in more efficient growth.

[0053] The filamentous growth layer 120 can form pores in various ways, and preferably, the filamentous growth layer 120 can be made of a porous sheet to form multiple pores.

[0054] The filamentous growth layer 120 can be composed of a biodegradable material, similar to the base film layer 110, and can be composed of one or more of the following materials: PBAT (Poly-Butylene Adipate Terephthalate), PBS (Polybutylene Succinate), PHA (Polyhydroxy alkanoate), PLA (PolyLactic Acid), PCL (Polycaprolactone), cross-linked PVA (Polyvinyl Alcohol), PGA (Polyglycolic Acid), modified cellulose, and starch-modified resin.

[0055] Since the filamentous growth layer 120 is also made of biodegradable material, it can be buried in the ground when discarded, and after being buried, it biodegrades within a few months, thus not causing environmental pollution. Furthermore, because it is flexible, it can be manufactured in a roll shape, offering advantages in terms of manufacturing and handling.

[0056] The filamentous body protective layer 130 is modeled after the columnar layer (PL) of the oyster shell 10, and is formed on the upper surface of the filamentous body growth layer 120. It allows the seaweed filamentous bodies to pass through and penetrate the filamentous body growth layer 120, and after the seaweed filamentous bodies have passed through, it protects them from the outside.

[0057] The filamentous protective layer 130 has multiple micropores 132 through which the nori filamentous material passes, and the micropores 132 are formed as pores with a diameter of approximately 10 to 100 μm, penetrating the filamentous protective layer 130 and moving toward the filamentous growth layer 120.

[0058] The filamentous protective layer 130 has a constant thickness of 1 to 20 μm and is formed of a material that is physically or chemically treated to create micropores 132, or has a fibrous structure that forms micropores 132, like a nonwoven fabric.

[0059] The filamentous protective layer 130 is also composed of one or more of the following biodegradable materials: PBAT (Poly-Butylene Adipate Terephthalate), PBS (Polybutylene Succinate), PHA (Polyhydroxy alkanoate), PLA (PolyLactic Acid), PCL (Polycaprolactone), cross-linked PVA (Polyvinyl Alcohol), PGA (Polyglycolic acid), modified cellulose, and starch-modified resin. It can be buried in the ground when discarded, and after burial, it biodegrades within a few months, thus not causing environmental pollution. Furthermore, it is flexible and can be manufactured in roll form, offering advantages in manufacturing and handling.

[0060] The filamentous protective layer 130 may contain an antibacterial agent to protect the filamentous seaweed from viruses and bacteria, and may also contain a deodorant to remove odors.

[0061] On the other hand, as described above, only examples have been given in which the filamentous growth layer 120 is formed on the upper surface of the base film layer 110 and the filamentous protection layer 130 is formed on the upper surface of the filamentous growth layer 120. However, as shown in Figure 3, the filamentous growth layer 120 can also be formed on the lower surface of the base film layer 110, and the filamentous protection layer 130 can also be formed on the lower surface of the filamentous growth layer 120 formed on the lower surface of the base film layer 110.

[0062] In other words, the filamentous growth layer 120 and the filamentous protection layer 130 are formed on both sides of the base film layer 110.

[0063] Furthermore, as shown in Figures 3 and 4, the base film layer 110, the filamentous growth layer 120, and the filamentous protection layer 130 can each have culture water passage holes 150 that communicate with each other and allow the culture water to pass from the base film layer 110 to the filamentous protection layer 130, or from the filamentous protection layer 130 to the base film layer 110.

[0064] Such a double-sided structure consisting of a filamentous growth layer 120 and a filamentous protective layer 130, as well as culture water passage pores 150, is a very effective structure when using the seaweed filamentous culture film of the present invention as a substitute for a suspended oyster shell bundle. A detailed explanation will be given later in the description of the seaweed filamentous culture apparatus.

[0065] Figures 5(a) to (c) show various examples of projections that form a space between the filamentous growth layer and the filamentous protection layer where the filamentous organisms of seaweed can grow.

[0066] As shown in Figure 5, a space 140 is provided between the filamentous protective layer 130 and the filamentous growth layer 120, in which the filamentous nori filaments that have penetrated the filamentous growth layer 120 can grow.

[0067] This space 140 can be formed by a projection 145 protruding from the filamentous body protective layer 130 as shown in Figure 5(a), or from the filamentous body growth layer 120 as shown in Figure 5(b), or from both the filamentous body protective layer 130 and the filamentous body growth layer 120, between the filamentous body protective layer 120 and the filamentous body growth layer 120 as shown in Figure 5(c).

[0068] Multiple protrusions 145 can protrude at intervals of 10 μm to 1 mm or less, separated in the vertical and horizontal directions, etc., but this is just one example, and their protrusion morphology and pattern are not limited.

[0069] On the other hand, since the filamentous protective layer 130 and the filamentous growth layer 120 are joined by the protrusions 145, the bonding strength can be improved.

[0070] Figure 6 is a perspective view of the seaweed filament culture apparatus of the present invention, Figure 7 shows one configuration in which a seaweed filament culture film is inserted into a seaweed filament culture housing, which is one component of the seaweed filament culture apparatus of the present invention, and Figures 8(a) and (b) are side views illustrating a configuration in which the apparatus is erected and fixed by the fixing means shown in Figure 7.

[0071] Referring to Figures 6 to 8, the nori filamentous tissue culture apparatus according to an embodiment of the present invention comprises a nori filamentous tissue culture housing 210, which is filled with culture water and provides a culture environment in which nori filamentous tissue can be cultured, and a nori filamentous tissue culture film 220, into which nori filamentous tissue can penetrate and which is inserted into the nori filamentous tissue culture housing 210 and can be cultured.

[0072] Specifically, the seaweed filament culture housing 210 is formed such that its top surface is open for the insertion of the seaweed filament culture film 220, and the remaining surfaces, excluding the open top surface for filling with culture water, are closed. Here, the open top surface may be provided with a door (not shown) for selective closure as needed.

[0073] Furthermore, the seaweed filament culture housing 210 is equipped with fixing means 230 for fixing the seaweed filament culture film 220 inserted inside.

[0074] The fixing means 230 can be configured to fix the seaweed filament culture film 220, which is inserted into the seaweed filament culture housing 210, in an upright position.

[0075] Here, "standing" means either the state in which the seaweed filamentous culture film 220 is standing vertically relative to the bottom surface of the seaweed filamentous culture housing 210, as shown in Figure 8(a), forming a right angle with the bottom surface of the seaweed filamentous culture housing 210, or the state in which the seaweed filamentous culture film 220 is standing diagonally relative to the bottom surface of the seaweed filamentous culture housing 210, forming an inclination angle (α) with the bottom surface of the seaweed filamentous culture housing 210, as shown in Figure 8(b).

[0076] The fixing means 230 is not limited to any particular form, and as an example, it can be configured in a way that allows the nori filamentous culture film 220 to be slidably inserted and fixed from above to below.

[0077] The fixing configuration of the fixing means 230 is such that the nori filamentous culture film 220, which passes through the open upper surface of the nori filamentous culture housing 210, can be easily inserted into or detached from the fixing means 230.

[0078] On the other hand, the fixing means 230 may be provided as a single unit, but preferably, multiple fixing means 230 may be provided so that multiple nori filament culture films 220 can be fixed.

[0079] At this time, the multiple fixing means 230 are spaced apart at regular intervals in a certain direction, so that when the multiple nori filamentous culture films 220 are fixed by the multiple fixing means 230, they are arranged at regular intervals in one direction.

[0080] When the seaweed filament culture film 220 is fixed by the fixing means 230 to form a constant interval in one direction, there is an advantage in that the culture water and culture environment provided to the seaweed filament culture film 220 can be provided relatively evenly.

[0081] Furthermore, the fixing means 230 may be provided in a form that fixes one nori filamentous culture film 220 in one direction, or, as shown in the figure, it may be provided in a form that fixes the nori filamentous culture film 220 in two directions.

[0082] In other words, the fixing means 230 may be provided in a form in which a pair of fixing means 230, which are provided in both directions, fix both corner portions of a single seaweed filament culture film 220, as shown in the figure.

[0083] In this case, the fixing means 230 on one side and the fixing means 230 on the other side can be arranged to face each other on the same line, or they can be arranged to be angled apart and not on the same line.

[0084] Furthermore, the fixing means 230 may be provided in a configuration in which multiple fixing means 230 are fixed to one nori filament culture film 220 in one direction. That is, multiple fixing means 230 may be fixed to one side corner portion of one nori filament culture film 220.

[0085] Figure 9 is an exploded view of the seaweed filament culture apparatus of the present invention, and Figures 10(a) to (d) illustrate various forms of the display means shown in Figure 9.

[0086] Furthermore, Figure 11 is a side cross-sectional view illustrating the circulation of culture water inside and outside the nori filamentous culture film, and Figure 12 is a front cross-sectional view of a nori filamentous culture apparatus for explaining the structure and relationship between the nori filamentous culture film and the lighting means.

[0087] Referring to Figures 9 to 12, the nori filamentous tissue culture housing 210 is equipped with a temperature controller 240, a culture water circulator 250, a lighting means 260, a growth environment measuring means 270, a display means 280, and a control means 290, which provide a culture environment in which filamentous tissue can be cultured.

[0088] The temperature controller 240 can adjust the temperature of the culture water, the culture water circulator 250 can generate a flow in the culture water so that the culture water circulates inside the seaweed filament culture housing 210, and the lighting means 260 provides artificial light inside the seaweed filament culture housing 210.

[0089] Furthermore, the growth environment measuring means 270 includes a camera 271 for photographing the growth of the nori filamentous organisms, a temperature sensor 272 for measuring the temperature of the culture water, a salinity sensor 273 for measuring the salinity of the culture water, and an illuminance sensor 274 for measuring the illuminance of the nori filamentous organism culture housing, and observes or measures the growth environment of the nori filamentous organisms in real time or periodically.

[0090] Furthermore, the display means 280 is configured to output the information measured by the growth environment measurement means 270 so that it can be visually confirmed, and so that the user can input growth environment control commands.

[0091] The control means 290 is connected to the temperature controller 240, the culture water circulator 250, the lighting means 260, the growth environment measuring means 270, and the display means 280, and controls one or more of the temperature controller 240, the culture water circulator 250, and the lighting means 260 according to growth environment control commands input by the user.

[0092] Next, the seaweed filament culture film 220 may be the same film as the seaweed filament culture film 220 of the present invention described above in Figures 2 to 5. However, this is merely a preferred form, and any film capable of cultivating seaweed filaments can be used.

[0093] In other words, although the nori filamentous culture film 220 described below is indicated with different reference numerals in the drawings than the nori filamentous culture film 100 exemplified in Figures 2 to 5 for the purpose of distinction, it should be noted that, as shown in Figure 6, it may be the same film.

[0094] The aforementioned seaweed filamentous culture film 220 is inserted into the seaweed filamentous culture housing 210, and the seaweed filamentous is cultured using the culture water filling the seaweed filamentous culture housing 210, the provided culture environment, and external natural light.

[0095] One or more of the seaweed filament culture films 220 can be inserted into the seaweed filament culture housing 210, and multiple seaweed filament culture films can be arranged at regular intervals in one direction by fixing means 230 provided in the seaweed filament culture housing 210.

[0096] At this time, one direction in which the multiple nori filament culture films 220 face may be the direction in which the culture water flow is generated by the culture water circulator 250.

[0097] For example, when the culture water circulator 250 generates a flow of culture water from the front to the back of the seaweed filament culture housing 210, the arrangement direction of the multiple seaweed filament culture films 220 will be aligned towards the front.

[0098] Furthermore, the nori filamentous culture film 220 has at least one corner that is separated from the nori filamentous culture housing 210, or it has culture water passage holes 225 that allow culture water to pass through inside, preferably at least one corner that is separated from the nori filamentous culture housing 210 and also has culture water passage holes 225.

[0099] Here, the corner separating the nori filamentous culture film 220 from the nori filamentous culture housing 210 is the lower corner, as shown in Figure 11, but it is not necessarily limited to this.

[0100] As a result, the culture water generated in the culture water circulator 250 can circulate smoothly with minimal resistance inside or outside the seaweed filamentous culture film 220, or both inside and outside, and culture water can be supplied to each seaweed filamentous culture film 220 both inside and outside.

[0101] The nori filamentous culture film 220 is formed with a width (a) that is longer than its height (b), and is inserted into the nori filamentous culture housing 210 with its width facing the bottom surface of the filamentous culture housing 210.

[0102] Although the nori filamentous culture film 220 is shown in the figure as a rectangular shape, this is merely one example, and the shape is not limited.

[0103] In the case where the nori filamentous culture film 220 is formed with a width (a) longer than its height (b), the lighting means 260 provided in the nori filamentous culture housing 210 can be arranged to irradiate artificial light toward the height (b) direction of the nori filamentous culture housing 210.

[0104] In this case, the width (a) of the nori filamentous culture film 220 is formed to be longer than the vertical height (b), so the illuminance difference between the top and bottom of the nori filamentous culture film 220 becomes relatively small.

[0105] Here, more preferably, the lighting means 260 may be arranged in a row spaced apart in the width direction of the seaweed filament culture film 220 in order to supply artificial light as uniformly as possible, and if multiple seaweed filament culture films 220 are provided, multiple groups of lighting means 260 spaced apart in the width direction may also be formed in a row in the direction of arrangement of the seaweed filament culture films 220.

[0106] Furthermore, the nori filamentous culture film 220 may be inserted into the nori filamentous culture housing 210 with at least one corner portion supported by the frame 300, as shown in Figure 7.

[0107] The frame 300 is formed in such a way that it can be attached to the seaweed filament culture housing 210 or fixed to the fixing means 230, and supports the seaweed filament culture film 220 in the attached or fixed position.

[0108] More preferably, all corners of the seaweed filament culture film 220 are supported by the frame 300 and inserted into the seaweed filament culture housing 210, thereby minimizing movement.

[0109] The frame 300 is made of a material that can be reused multiple times, and can be made to be used by simply replacing the seaweed filament culture film 220.

[0110] Conventional cultivation of filamentous seaweed was carried out using oyster shells consisting of a lime layer, a nacreous layer located above the lime layer, and a stomatal layer located above the nacreous layer. However, the filamentous seaweed cultivation film of the present invention mimics the stomatal layer, nacreous layer, and lime layer of an oyster shell to cultivate filamentous seaweed. It is lighter, exhibits a higher penetration rate and growth rate of the filamentous organisms, can be used as an effective substitute for oyster shells, and has the advantage of being able to substitute for multiple bundles of oyster shells depending on the size of the film.

[0111] In particular, conventional hanging-type nori filament cultivation methods involved suspending bundles of oyster shells, each tied together, from a rod and immersing them in a deep tank filled with seawater for cultivation. However, the nori filament cultivation apparatus of the present invention has the effect of replacing the multiple bundles of oyster shells that were previously suspended from a rod by using a nori filament cultivation film upright inside the nori filament cultivation housing.

[0112] In this case, compared to multiple bundles of oyster shells suspended from a single rod, the nori filamentous culture film reduces weight to approximately 1 / 13, costs to approximately 1 / 5, and increases area utilization efficiency by approximately 15% or more.

[0113] Furthermore, since the seaweed filament culture apparatus of the present invention does not require the suspension of the film, it does not require the use of rods, and the spacing between seaweed filament culture films can be made even narrower than the spacing between conventional oyster shell bundles, making it possible to provide a uniform culture environment including uniform lighting, and thereby increasing the productivity of seaweed filament culture.

[0114] Furthermore, the seaweed filament culture apparatus of the present invention is designed to allow users to easily adjust the culture environment while visually observing it in real time, and to facilitate the fixing and replacement of the seaweed filament culture film, thereby improving the convenience of cultivation.
