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.

[0027] 1. Application examples

example 1

[0028] Example 1: Taking the content of water-soluble arabinoxylan in wheat bran that has not been degraded and fermented by Agaricus blazei as a control, using Agaricus blazei liquid fermentation to degrade and metabolize the water-soluble arabinoxylan in the wheat bran medium, and significantly reduce its content.

[0030] control

example 2

[0031] Example 2: Taking the total sugar content in the wheat bran liquid culture medium without degradation and fermentation of Agaricus blazei as a control, comparing the insoluble non-starch polysaccharides in wheat bran degraded by Agaricus blazei liquid fermentation, significantly increasing the available soluble polysaccharides .

Abstract

The invention provides a method about biodegrading wheat bran araboxylan, The method adopts edible Agaricus blazei Murill which can be used as medicine and food as biodegradable probiotic bacteria, through adopting a liquid culture technology and culture medium in a particular screened way, to induce the extracellular compound fiber degeneration enzyme system of the biodegraded fungus is induced to degrade the wheat bran araboxylan is degraded and the utilization efficiency, therefore, the nutrition converting utilization efficiency by adopting the wheat bran 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...
