Three-step enzymatic hydrolysis method used for producing forage saccharomyces cerevisiae cells with broken-down walls

Abstract

The invention provides a forage symbiotics mild production method used for producing saccharomyces cerevisiae cells with broken-down walls, wherein a product of the forage symbiotics mild production method comprises yeast metabolites such as yeast protein, yeast steroid, yeast polysaccharide, and yeast nucleic acid. The saccharomyces cerevisiae cells with broken-down walls can be used a novel forage additive so as to solve problems of low protein utilization ratio, high diarrhea ratio, and high morbidity in the field of animal husbandry. According to the forage symbiotics mild production method, yeast bacteria are obtained via submerged liquid state fermentation, and then the saccharomyces cerevisiae cells with broken-down walls are obtained via three-step enzymatic hydrolysis method. Production cost is low, viable count is high, and the saccharomyces cerevisiae cells with broken-down walls is a green forage additive with stability and high efficiency. Process route is disclosed in a attached figure.

Description

technical field [0001] The invention relates to a preparation method of broken yeast cells for feeding. technical background [0002] Yeast can convert low-quality protein into high-quality protein and provide high-quality protein feed for animals. At the same time, yeast cell wall cells contain a large amount of yeast protein, yeast nucleic acid, yeast steroids and other nutrients, which can regulate immunity, improve animal disease resistance, reduce The use of antibiotics is an excellent green feed additive. The breakage of yeast cell wall is mainly through mechanical method, chemical method and enzymatic method, but the application of enzymatic method is seldom, because the cracking effect of single enzymatic method is poor. The mechanical method is noisy, and the chemical method produces a large amount of sewage, which easily leads to the residue of chemicals in the feed. [0003] The method is to use Saccharomyces cerevisiae approved by the Ministry of Agriculture to...
