Abstract

The invention belongs to the technical field of microorganisms and discloses a method for fermenting and producing streptomycin from compound coat blood replenishing oral liquid dregs. The method comprises the steps as follows: inoculating a streptomyces culture medium prepared from the compound coat blood replenishing oral liquid dregs with a streptomyces griseus seed culture solution in the inoculum size of 10%, and performing fermentation at 32-35 DEG C for 72 h or longer at 200-300 rpm and the ventilation amount of 0.3-0.4 vvm; during fermentation, supplementing glucose to control the concentration of glucose in a fermentation liquid not lower than 0.5%. The method uses the dregs and changes waste into wealth.

Description

technical field [0001] The invention belongs to the technical field of microbes, and in particular relates to a method for producing streptomycin by fermenting medicinal dregs of compound Hongyi Buxue oral liquid. Background technique [0002] Streptomyces is the main strain producing streptomycin. Streptomycin is an antibiotic extracted from the culture solution of Streptomyces griseus, which belongs to the aminoglycoside basic compound and is the main drug for the treatment of Mycobacterium tuberculosis. Because the pain response of intramuscular injection of streptomycin is relatively small, it is suitable for clinical use. As long as the application target is selected properly and the dose is relatively appropriate, most patients can be injected for a long time. During the preparation of streptomycin by Streptomyces fermentation, culture medium is needed, and the culture medium generally uses components such as yeast extract and glucose, which are expensive; with the in...
