Method for biodegradation of wheat bran araboxylan

Abstract

The invention provides a method for biodegrading wheat bran araboxylan. The method adopts edible Agaricus blazei Murill which can be used as medicine and food as biodegradable probiotic bacteria, and a liquid culturing technique and a culture medium particularly selected are adopted to induce an extracellular compound fiber degeneration enzyme system of the biodegraded fungus to degrade the wheat bran araboxylan and to improve the transformation utilization efficiency, therefore, the nutrition converting utilization efficiency of the wheat bran when being adopted as the feed resource is enhanced.

Description

technical field [0001] The invention belongs to the field of biotechnology, and more specifically relates to a method for biodegrading wheat bran arabinoxylan. Background technique [0002] Bran is the main by-product of wheat processing, accounting for 20% of the total processing. In livestock and poultry production, because wheat bran contains a large amount of anti-nutritional components, its degradation efficiency is low, which limits its effective utilization as animal feed resources. Feeding practice shows that if the content of wheat bran in the diet of monogastric animals is too much, the production performance of livestock and poultry will be reduced, and the quality of carcass will be reduced. On the one hand, it is directly related to the content of soluble arabinoxylan, the main component of wheat bran non-starch polysaccharide; on the other hand, it is also affected by the insoluble non-starch polysaccharide (including insoluble arabinoxylan) in wheat bran, inh...

Problems solved by technology

However, in the prior art, NSP enzyme-derived microorganisms for the degradation of wheat bran arabinoxylan generally have defects such as low enzyme activity, heat resistance, and poor acid resistance, and the enzyme production efficiency is low, and the research on β-glucanase Most of them focus on Bacillus, while the degradation of arabinoxylan mainly uses fungal species such as Aspergillus niger and brown root enzymes, and there are few reports on the degradation and utilization of edible fungi.
