Abstract

The invention provides a culture medium for culture expanding and concentration of oocystis species, wherein the culture medium comprises a nutrient solution A and a nutrient solution B. The nutrientsolution A comprises the following components: NaNO3, sodium dihydrogen phosphate dihydrate, disodium EDTA and ferric chloride hexahydrate. The nutrient solution B comprises the following components:citric acid, ferric ammonium citrate, calcium chloride dihydrate, boric acid, manganese chloride, zinc sulfate, sodium molybdate, copper sulfate, cobalt nitrate, vitamin B1, vitamin B12 and biotin. The invention provides a culture medium for culture expanding and concentration of oocystis species rapid in growth of oocystis species, strong in growth vigor and low in death rate.

Description

technical field [0001] The invention relates to the technical field of aquaculture microorganism cultivation, in particular to a culture medium for expanding and concentrating oocyst algae species. Background technique [0002] Oocysts are common planktonic green algae that exist in various waters in China, belonging to Chlorophyta, Chlorophyceae, Chlorococcuses, Oocystaceae, and can be distributed in fresh water. The plant body is a spherical or elliptical spherical group, and the group is usually composed of 2, 4 or 8 cells, and there is a gelatinous coating composed of pectin outside the group. The algae cells are oval or oval, with a length of 10 μm-19 μm and a width of 9.0 μm-13 μm. Generally, 2, 4, 8 or 16 spore-like spores can be produced. [0003] In the prior art, the medium for oocyst algae species only contains the nutrients required by conventional oocysts, and the production activity of oocysts is not enough, and the growth rate is not fast enough, and the mort...
