Problems solved by technology

However, this type of PBR is usually expensive, high operating cost, difficult to maintain, difficult to scale up, and the yield is 5-30g/m 2 /d, far lower than the theoretical prediction value of 100-200g/m 2 /d, the theoretical calculation target of industrialization cannot be reached, and the light energy utilization rate is low, which is the most important direct constraint factor for the large-scale cultivation of microalgae to realize industrialization, which still needs to be improved
[0004] In recent years, a kind of semi-dry culture system has appeared, and there have been patent reports, all of which use one or more of filter paper, filter cloth, sponge, foam plastic, fiber fabric (such as canvas) as the matrix material, but this type Soft materials have the following disadvantages: 1) low mechanical strength, requiring complex supports, not suitable for large size and space height enlargement,

Abstract

The invention discloses a surface growth type photosynthetic microorganism culture plate having a core-shell structure, which comprises a shell plate arranged outside and a core part arranged in the shell plate, wherein the shell plate is of a porous plate-shaped structure made from a rigid water seepage material; the filling core is made from a water retention and water seepage material; and the filling core is arranged in the shell plate. According to the core-shell type composite culture plate disclosed by the invention, photosynthetic microorganisms are attached to the surface, a nutrient solution for supporting growth of the photosynthetic microorganisms is retained in the filling core, and the nutrient solution gradually permeates to the surface of the shell plate from the filling core and then is supplied for sustainable reproduction of the photosynthetic microorganisms. In addition, the invention further discloses a culture unit comprising the core-shell type composite culture plate, a culture system, a culture method and application thereof.

Description

technical field [0001] The invention relates to a surface growth type photosynthetic microorganism culture plate with a core-shell structure, a culture unit comprising the culture plate, a surface growth type culture system, a method and an application thereof. Background technique [0002] Photosynthetic microorganisms are a kind of microorganisms that use light as the only or main source of energy to grow and reproduce, including microalgae, cyanobacteria and other microorganisms that contain chlorophyll and can perform photosynthesis. Microorganisms have important biological utilization value. According to current literature reports, algae are rich in protein and can be used as aquatic bait or feed for livestock and poultry (such as spirulina); more importantly, some microalgae can synthesize a large amount of secondary metabolites under specific conditions, such as oil, carotenoid, Polysaccharides, etc. These substances are often biologically active substances with extre...
