Problems solved by technology

[0004] 1 Spectinomycin seeds and the composition of organic nitrogen sources in the fermentation medium are at least three, which increases the purchase cost of the enterprise
[0005] 2 The first-level seed inoculation amount is more
The inoculum volume of conventional primary seed culture is 5-10L / M 3 , increasing the work intensity of strain researchers
[0006] 3 The seed culture cycle of spectinomycin with conventional formula is longer, and the cycle of two seed cultures exceeds 50h
In addition, the price of purchasing pure fishmeal is relatively high, and it is easily affected by the fishing moratorium, which increases the purchase cost and production cost
[0008] 5 During the sterilization process of conventional medium, part of the glucose is easily carbonized at high temperature, which makes the color of seed liquid and fermentation liquid darker, reduces the total sugar content in the medium, and affects the effect of seed culture and fermentation culture

Abstract

The invention relates to a culture medium for fermentation production of spectinomycin through streptomyces spectabilis and a fermentation method. A primary seed culture medium, a secondary seed culture medium and a fermentation culture medium all contain corn oil, maltose, beer yeast dry residues and earthworm meal. According to the invention, maltose replaces glucose, beer yeast dry residues and earthworm meal replace fish meal, peptone, soybean cake meal and corn steep liquor, and the culture medium formula is optimized, so that the problem of high costs of raw materials is solved, the environmental effect on the source of the raw materials is reduced to the utmost extent, sufficient supply of the raw materials is guaranteed, and stable and efficient production of spectinomycin is realized. Meanwhile, the culture medium can improve the fermentation unit and shorten the fermentation period.

Description

technical field [0001] The invention belongs to the technical field of biological fermentation, and in particular relates to a culture medium and a fermentation method for producing spectinomycin by fermentation of Streptomyces spectiformis. Background technique [0002] Spectinomycin is a secondary metabolite produced by Streptomyces spectiosa through aerobic fermentation. It has the characteristics of broad bactericidal spectrum, no allergies, few side effects, and good safety. It is not only the first choice drug for treating gonorrhea, but also can be used for animal treatment, and can promote animal growth, and is a good animal feed additive. [0003] At present, the production method of spectinomycin in China is mainly the fermentation method, that is, Streptomyces spectiformis is used as the strain, and the carbon source in the medium is mainly starch and glucose; the organic nitrogen source is mainly corn steep liquor, yeast powder, soybean cake powder and Peptone. ...
