| titleOfInvention | Method for producing epsilon-polylysine by using cassava residue hydrolysate as carbon source |
| abstract | The invention discloses a method for producing epsilon-polylysine by using cassava residue hydrolysate as a carbon source, belonging to the technical field of fermentation engineering. In the epsilon-polylysine fermentation, the cassava residue enzyme hydrolysate is used as a carbon source, and the epsilon-PL batch fermentation is carried out according to the initial glucose concentration of 10-70g/L, so that the epsilon-polylysine can be effectively produced. Under the same condition, the shaking flask and the tank are used for batch fermentation, and the highest yield of epsilon-polylysine by utilizing hydrolysate is respectively 17.9 percent and 24.6 percent higher than that of glucose. Meanwhile, the producing strain shows stronger acid tolerance in the fermentation of hydrolysate. Combined with fed-batch fermentation, concentrated hydrolysate and mixed nitrogen source are fed-batch at the same time, and the highest yield of epsilon-polylysine reaches 37.41 g/L. The cassava residue hydrolysate is applied to epsilon-polylysine fermentation, so that the efficient production of epsilon-polylysine is realized, and the problem of environmental pollution caused by cassava residue treatment can be reduced. The method has the advantages of feasible operation, obvious effect and easy realization of industrial production. |
