A microbial culture method for enhancing the ability of planktonic microorganisms to feed on blue-green algae

Abstract

The invention discloses a microorganism culture method for enhancing blue-green algae ingestion capacity of planktonic microorganisms. The microorganism culture method includes the following specific steps that culture pools are built, fertilizer is applied to the culture pools, and then eutrophic pool water is obtained; composite algae culture solution is added to the eutrophic pool water; the temperature of the pool water of all the culture pools reaches 8-20 DEG C, and the planktonic microorganisms are transferred in the first culture pool; the planktonic microorganisms cultured in the first culture pool are transferred to the second culture pool, and the planktonic microorganisms cultured in the second culture pool are transferred to the next culture pool in the same way until the planktonic microorganisms high in blue-green algae ingestion capacity are obtained. The planktonic microorganisms high in blue-green algae ingestion capacity are domesticated through the similarly polluted eutrophic pool water and the special composite algae culture solution, and the planktonic microorganisms further have the advantages of being high in fertility and good in adaptability to the freshwater environment.

Description

technical field [0001] The invention relates to the field of microbes, in particular to a microbial culture method for enhancing the ability of planktonic microbes to feed on blue-green algae. Background technique [0002] The reason for the outbreak of blue-green algae is that various production activities of human beings discharge nitrogen and phosphorus nutrients into rivers, lakes and other water bodies. When the ecological self-purification ability of lakes is destroyed, nitrogen, phosphorus and other nutrients continue to accumulate in water bodies. A large number of single-celled algae, especially cyanobacteria (mainly Microcystis aeruginosa), are inundated and seriously polluted the water quality. [0003] Most of the cyanobacteria cells have a well-developed alginate layer, and the outside of the cell is surrounded by a thick layer of polysaccharides. These alginates and polysaccharides can hardly be decomposed by the digestive enzymes of any higher animals. Theref...

Problems solved by technology

However, the mesh required to salvage algae is too small and the water content is too high. From a commercial point of view, the cost of salvage is higher than the value of organic fertilizers

[0008] As we all know, water plants (such as water hyacinth, water peanut, water floating lotus, water vegetables, water flowers, etc.) can indeed absorb nutrients in the water body, but they block the water surface and cover the sunlight, causing some underwater organisms and mud bottom organisms. In particular, the death of submerged plants will cause a large amount of dissolution of nutrients in the sediment, and their disadvantages far outweigh their benefits
