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 xylanase is mixed, dried at high temperature and coated with fat. In addition, the present invention also provides the product produced by the method and the high-temperature-resistant dehydration xylanase and the like. Background technique

[0002] Xylanase can effectively degrade lignin-containing substances (such as feed), so adding xylanase 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 xylanase.

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