Lysine and cellulase fermented and coated feed

Abstract

The invention relates to lysine and cellulase fermented and a coated feed, and provides a method for preparing an L-lysine product by fermentation. The method comprises the steps: fermenting to produce an L-lysine fermented liquor, mixing the L-lysine fermented liquor with high-temperature-resisting dewatered cellulase obtained through the fermentation, and coating by using fat after high temperature drying. In addition, the invention also provides a product produced by using the method, the high-temperature-resisting dewatered cellulase and the like.

Description

technical field

[0001] The invention belongs to the field of fermentation of amino acids. Specifically, the invention relates to a method for fermenting and preparing L-lysine products, which includes fermenting and producing L-lysine fermentation broth, which can be dehydrated with fermentable high-temperature resistant The cellulase is mixed, dried at high temperature and coated with fat. In addition, the invention also provides the product produced by the method, the high temperature dehydration resistant cellulase and the like. Background technique

[0002] Cellulase can effectively degrade cellulose-containing substances (such as feed), so adding cellulase to feed can enhance the absorption and utilization of feed, thereby saving feeding costs. For example, Chinese patent 96196760.9 discloses an enzyme supplement for ruminant feed, which contains cellulase.

[0003] L-lysine is an important amino acid raw material, which can be used as condiment, food, feed additive,...
