Abstract

The invention relates to the technical field of enzymes, in particular to a complex enzyme composition for efficiently degrading corn xylan. The active ingredients of the complex enzyme composition for efficiently degrading corn xylan include xylanase a, xylan b, α-L-arabinofuranosidase and / or feruloesterase. The compound enzyme composition for efficiently degrading corn xylan can effectively degrade corn xylan specifically, and has high degradation efficiency and high feed utilization rate.

Description

technical field [0001] The invention relates to the technical field of enzymes, in particular to a composite enzyme composition for degrading corn xylan. Background technique [0002] With the rapid development of my country's animal husbandry, the demand for feed raw materials has also increased, and corn is the largest amount of feed raw materials in my country. According to the China Industry Information Network, in 2017-2018, my country's corn production was 210 million tons, and the import volume was 1.5 million tons, of which 140 million tons were consumed for feed (the xylan content was about 5.6 million tons), and the xylem in feed corn was 140 million tons. The sugar content is 3.7 times that of corn imports. Among the anti-nutritional factors of most feed materials, the content of xylan is the highest; although the content of xylan in different feed materials is basically the lowest, the amount of corn is the largest. There is no enzyme that degrades xylan in mono...
