Method for coculturing fine algae and photosynthetic bacteria

Abstract

The invention provides a co-culture method of micro-algae and photosynthetic bacteria, and the co-culture method belongs to the field of biotechnology. The co-culture method is characterized in that: the co-culture method adopts a translucent glass or plastic container as the container and adopts tap water for preparing a liquid culture medium, the liquid culture medium is composed of 0.2 to 1.0g / L of MgSO47H2O, 1.0 to 3.0g / L of NaHCO3, 0.01 to 0.02g / L of CaCl2, 1.0 to 3.0g / L of NH4Cl, 1.0 to 2.0g / L of KH2PO4, 1.0 to 5.0g / L of NaCl, 0.2 to 1.0g / L of yeast extract, 2.0 to 5.0g / L of sodium acetate and 1.0ml / L of trace element liquid. The micro-algae and the photosynthetic bacteria are co-cultured at the average temperature of larger than 20 DEG C and under the solar radiation after the inoculation, the micro-algae and the photosynthetic bacteria with the high cell concentration can be obtained after 5 days, the obtained biomass of the micro-algae or the biomass of the photosynthetic bacteria can be respectively improved by 65 percent or 100 percent compared with the single culture, thereby realizing the purpose of high efficient co-culture of the micro-algae and the photosynthetic bacteria, and an algae bacteria culture which is obtained by culture can be applied as a water quality purifier and a feed additive for the aquaculture.

Description

technical field [0001] The invention belongs to the field of biotechnology, and in particular provides a method for co-cultivating microalgae and photosynthetic bacteria. Background technique [0002] Microalgae belong to lower plants and are simple photosynthetic organisms. Chlorella is a single-celled green alga of the genus Chlorella of Chlorphyta. There are about 10 species. Common Chlorella species in my country include Chlorella ellipsoides, Chlorella vulgaris and pyrenoids algae etc. Chlorella is rich in protein, unsaturated fatty acids, carotenoids, lutein, astaxanthin and multivitamins, and has extremely high nutritional value and the function of improving immunity. In addition, the Chlorella Growth Factor in Chlorella not only induces interferon to activate immune cells, but also promotes the body's detoxification and excretion of harmful substances, and can promote the growth of brewer's yeast. At present, Chlorella is not only a good model organism in the study...
