Abstract

The invention relates to a production method capable of increasing yield of neomycin. According to the production method, one or several of additives which are lysine, ferrous lactate, tyrosine, methionine, hydrolysis casein, vitamin B12, fructose, glucosamine, folic acid, riboflavin and tryptophan are added to a conventional fermentation medium comprising peanut meal, corn starch, rice flour, yeast powder, glucose, peptone, ammonium sulfate, sodium chloride, light calcium carbonate and KH2PO4-containign streptomyces fradiae. The production method has the advantages that the yield of the neomycin is increased by above 5-20%, the cost is reduced, and the fermentation efficiency is high. The neomycin is used for treating human diseases, widely used in animal husbandries and used as antibiotics.

Description

Technical field [0001] The present invention provides a production method of neomycin, specifically, a production method for improving the production of neomycin. It is a preparation method that involves using microorganisms to ferment and increase the production of neomycin. Background technique [0002] Neomycin is an aminoglycoside antibiotic. Neomycin is the first 2-DOS (2-deoxystreptamine) aminoglycoside antibiotic to be discovered. It is an amino cyclic polysaccharide isolated from the metabolites of Streptomyces fradiae by Waksman et al. in 1949. The alcohol compound antibiotic mainly binds to the 30S subunit of the bacterial ribosome and inhibits the bacterial synthesis of protein. Streptomyces fradiae strains can be purchased commercially and are also strains used in the domestic neomycin microbial fermentation production process. Clinically commonly used neomycin sulfate (Neomycin Salfate), molecular formula: C23H46N6O13.3 (H2SO4). The product is white or slightly y...
