Problems solved by technology

At present, there are big problems in the extraction of omega-7 fatty acids by using these raw materials: 1) the content is low, and the preparation cost is high
Studies have shown that the content of omega-7 in deep-sea fish oil is only about 7%, which indirectly increases the production cost of omega-7 related products
The distribution and resources of deep-sea fish and nuts in my country are very limited, especially deep-sea fish, because overfishing can easily cause environmental problems and it is difficult to obtain them
The cultivation of seabuckthorn and nuts requires a lot of land, manpower and material resources, and there is seasonality, which is far from meeting the needs of the market
3) The product is unstable and contains high saturated fatty acids, which is not conducive to human health
However, in this invention, the palmitoleic acid in the seabuckthorn fruit oil is purified by a two-step method. Although it is quite effective, the collection of fruit oil and the purification and refining process are complicated, the operation cost is high, and industrial chemicals and high-temperature treatment are used to pollute the environment. The problem
[0009] 2) A method for preparing palmitoleic acid from macadamia nut oil and the application of palmitoleic acid (CN201910536726.X): This invention provides a method for preparing palmitoleic acid from macadamia nut oil, and the palm oil obtained by the method of the present invention Its palmitoleic acid is 1.5-5 times (16.85%) of the palmitoleic acid content of crude oil, and the preparation effect is not good enough, which is not conducive to industrial development and utilization. In addition, the oleic acid extracted from nut oil also exists in extraction and refining. and other complex process issues
At present, due to various limitations such as sources, palmitoleic acid content and quality, these raw materials do not yet have perfect industrialization value

Embodiment Construction

[0036] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0037] 1. Isolation and identification of high-quality Vischeria sp. LQ-1984 strain

[0038] The samples were taken from the seawater aquatic product (prawn) breeding pond in Maoming, Guangdong. After being brought back to the laboratory, they were placed in sterile seawater medium at a ratio of 1:5. -2 the s -1 , and the temperature is 20±1°C for enrichment culture for 3-5 days. After the water sample has a color visible to the naked eye, under sterile conditions, use the dilution coating method or the streaking method to separate and purify the pre-cultured culture on a solid plate, and place the plate on a light culture rack under the above conditions for 7- After 15 days, the above separation steps were repeated sev...

Abstract

The present invention discloses Veisseria sp. cultured by sea water, namely a Veisseria sp. LQ-1984 strain. The Veisseria sp. LQ-1984 strain has a number of LQ-1984, has a Latin name of Vischeia sp.,has an accession number of CCTCC M 20191120, and is named as Vischeia sp. LQ-1984. Mature cells of the Veisseria sp. LQ-1984 has a smooth surface, has no protrusion in the cell wall, has a diameter of10-15 microns, is of a spherical shape or a nearly spherical shape, has chlorophyll with a lobate shape, and contains a protein nucleus. Compared with other omega-7 fatty acid production raw materials, the Veisseria sp. LQ-1984 strain is not limited by environments, regions, seasons and the like, and can meet huge raw material gaps. The Veisseria sp. LQ-1984 strain contains high-content of omega-7 fatty acid, and high-quality algae powder of the Veisseria sp. LQ-1984 strain can be used for producing omega-7 related health care products, foods, cosmetics and the like.

Description

technical field [0001] The invention relates to microalgae, in particular to a strain of Welshmannii cultivated by seawater. Simultaneously, the present invention also relates to the application of the wilsoni algae. Background technique [0002] The currently reported microalgae used to produce omega-7 fatty acids are mostly freshwater microalgae. With the increasing shortage of freshwater resources in the world, the cultivation of freshwater microalgae is greatly restricted. In addition, there are many problems in the cultivation of freshwater microalgae. , such as algae pollution, protozoan predation, microcystin residues and heavy metal enrichment, etc. In response to this problem, this patent provides a strain of Vischeria sp. LQ-1984, which can grow in seawater with different salinities, and only needs to add carbon, nitrogen, phosphorus, iron, etc. on the basis of natural seawater. Elements can meet its growth needs, not only can greatly save fresh water resources, ...
