Abstract

The invention provides Fe2+ ion for promoting the proliferation of paenibacillus polymyxa and the application method thereof. An adopted culture medium is formed by adding Fe2+ into a PDB culture medium till the concentration is 50mg / L, and is equal to FeSO4.7H2O with the final concentration of 248.21mg / L. The Fe2+ ion can improve the proliferation biomass of paenibacillus polymyxa, shorten the proliferation lag phase of paenibacillus polymyxa, and ensure that the log phase of proliferation is in advance. The Fe2+ ion has an important theoretical significance on high efficient culture of paenibacillus polymyxa, and has a wide promotion value for the application of relevant biological bacterium agents.

Description

technical field [0001] The present invention relates to a kind of Fe 2+ The ion promotes the proliferation of Paenibacillus polymyxa and its application method, belonging to the technical field of biopesticides and biomedicine. Background technique [0002] Paenibacillus polymyxa in ginseng has a variety of physiological and pharmacological activities. It can produce a series of biologically active substances, such as nitrogenase, plant hormones, polysaccharides, hydrolytic enzymes, antibiotics, etc., which have great application value in biological nitrogen fixation, promotion of plant growth, development of new antibiotics, and inhibition of plant diseases. With the increase of environmental pressure and the improvement of people's health and food safety requirements, microbial pesticides have received more and more attention. The present invention adopts the ginseng endogenous Paenibacillus polymyxa strain isolated from ginseng plants, and the fermentation liquid of the...
