| titleOfInvention | A method for fermenting and producing erythromycin |
| abstract | The invention belongs to the field of biological fermentation production and provides a method for fermenting and producing erythromycin. The method uses Saccharopolyspora erythraea as the starting bacterium, and mainly includes four steps: preparation of slant strains, preparation of shake flask seed liquid, seed liquid cultivation and fermenter process control. The present invention uses refined cottonseed oil instead of soybean oil in seed tanks, fermenter culture medium and fermentation process feeding materials, which reduces the fermentation cost, and makes the fermentation titer of erythromycin and the content of erythromycin A equal on the basis of optimizing the fermentation process. It has been greatly improved and is suitable for industrialized large-scale production. |
