Abstract

The invention relates to a method for producing acid xylanase from whey powder. The method comprises the following steps of: culturing a strain in a shaking flask by taking trichoderma reesei as an original strain; performing primary seed culturing; performing secondary seed culturing; fermenting; performing primary filtration; performing secondary filtration; performing ultrafiltration and condensation; testing and blending; performing fine filtration and filling so as to obtain food grade liquid enzyme; drying and smashing a food grade liquid acid xylanase product by taking starch or bulked starch as an absorptive carrier so as to obtain a food grade solid acid xylanase preparation product; and spray-drying and smashing the food grade liquid acid xylanase product so as to obtain the food grade solid acid xylanase preparation product. The acid xylanase production process is simple, fast in strain reproduction, high in contaminated microbe resistance, and has short period, high equipment utilization ratio and low cost; and the obtained xylanase product has high activity. The xylanase, cellulose and beta-glucanase in the product have coordinated component content proportion and the product is most suitable for feed industry and beer industry.

Description

[0001] Field technology

[0002] The invention relates to a production method of xylanase, in particular to a method for producing acid xylanase by using whey powder. Background technique

[0003] Xylanase refers to the general term for a group of enzymes that can degrade xylan into oligosaccharides and xylose, mainly including β-1,4 xylanase and β-xylosidase, which can degrade xylanase in plants Degrade xylan into monosaccharides. Xylanase is a new type of enzyme preparation, which is currently mainly used in feed, beer, and other industries.

[0004] As a feed additive, xylanase can effectively hydrolyze anti-nutritional factors such as non-starch polysaccharides and crack plant cell walls, reduce viscosity, promote the release of plant effective substances and the absorption of nutrients, enhance animal production capacity and disease resistance, and reduce livestock , Poultry morbidity, reduce pollution caused by animal excrement. Improve feed utilization and reduce feed...
