Abstract
The invention provides a formula of an anabaena culture medium, comprising 200-250 mg / L NH4NO3, 500-550 mg / L NaNO3, 400-500 mg / L K2SO4, 150-200 mg / L of CaC12.2H2O, 100-150 mg / L MgSO4.7H2O, 400-500 mg / L K2HPO4, 15-20 mg / L Na2S2O3.5H2O, 20-25 mg / L H3BO3, 2-4 mg / L CuSO4.5H2O, 0.2-0.4 mg / L ammoniumferric citrate, 0.1-0.2 mg / L nicotinic acid, 0.2-0.3 mg / L vitamin B, 0.2-0.3 mg / L vitamin B1, 0.05-0.1 mg / L NNA and 0.03-0.05 mg / L IBA. The culture medium provided by the invention has the advantages of high survival rate and high growth rate while cultivating the anabaena, and are less prone to being polluted by other bacteria.
Description
technical field [0001] The invention relates to an algae culture medium, in particular to a culture medium formula of Anabaena. Background technique [0002] Anabaena blooms can fix free nitrogen in the atmosphere and are a type of nitrogen-fixing cyanobacteria. It grows and reproduces rapidly, and its nitrogen fixation capacity reaches 10-51kg / ha. After its algae sink into the soil, it can be absorbed by the roots of crops. A good organic fertilizer. The production and application of agricultural chemical fertilizers and pesticides will bring a large amount of greenhousegas emissions. Therefore, the development of agricultural biological nitrogen fixation technology and the reduction of chemical fertilizer application are important ways to develop low-carbon agriculture. The uses of Anabaena blooms mainly include: extraction of natural pigments, phycobiliproteins and polysaccharides, research and utilization of algal toxins, biological nitrogen fixation and other aspects...
