| titleOfInvention | Culture medium for producing erythromycin by fermenting streptomyces erythreus and fermentation method thereof |
| abstract | The invention relates to a culture medium for producing erythromycin by fermentation of streptomyces erythreus and a fermentation method thereof, wherein the culture medium comprises a seed culture medium consisting of starch, corn steep liquor, ammonium sulfate, light calcium carbonate, zinc sulfate, magnesium sulfate and a proper amount of defoaming agent, and a fermentation culture medium consisting of starch, corn steep liquor, ammonium sulfate, calcium carbonate, magnesium sulfate, zinc sulfate and a proper amount of defoaming agent. According to the invention, the metabolic pathway of thalli is changed by changing the formula structure of seeds and a fermentation medium, changing the formula structure of feed supplement and a control mode, and introducing a plurality of microelements, so that the three-stage fermentation is shortened to the two-stage fermentation, and the fermentation time is saved; meanwhile, the cost of fermentation raw materials is reduced, the fermentation culture medium is diluted, oxygen supply in the fermentation process is improved, and the energy consumption of oxygen supply is reduced. |
