| titleOfInvention | Method for stably and rapidly producing epsilon-polylysine |
| abstract | The invention relates to a method for stably and rapidly producing epsilon-polylysine, belonging to the technical field of fermentation engineering. The method for producing the epsilon-polylysine comprises the following steps: the strain streptomyces diastatochromogenes is adopted to carry out fermentation culture in a culture medium containing proper carbon sources and nitrogen sources. The invention takes the spore suspension for direct inoculation, takes the pH end point as the index of seed transfer, adopts the one-step method pH reduction strategy to carry out stable and rapid fermentation production of epsilon-polylysine, improves the yield by 80-130 percent compared with the conventional process, and shortens the period by 28-45 percent. The invention changes the existing production process steps, thereby simplifying the existing fermentation production method, obviously improving the production strength of the epsilon-polylysine, shortening the fermentation period, saving the cost, reducing the discharge of fermentation waste liquid and waste gas, and lightening the environmental pollution. |
