Application of oleaginous yeast in biological feed product

Abstract

The invention relates to the field of biological feeds, in particular to application of oleaginous yeast in a biological feed product, the main components of the application of the oleaginous yeast in the biological feed product comprise an oleaginous yeast culture solution and a catalytic enzyme solution, the oleaginous yeast culture solution is obtained by inoculating oleaginous yeast into a culture solution with the pH value of 3.4-3.9 for culture, the initial concentration of the oleaginous saccharomycetes in the culture solution is (1.2-1.5) * 100 cells / mL, the catalytic enzyme solution is composed of a protease solution and distilled water, the protease solution is acid protease, the PH value is 2-4, and the protease solution is bacillus subtilis secreted gelatinase and casein and can hydrolyze gelatin and casein. The microbial oil is prepared in the culture solution through the oleaginous saccharomycetes, synchronous purification and oil production of the feed by the oleaginous saccharomycetes can be realized, sterile conditions are not required to be created at high temperature and high pressure, and the method has the advantages of low equipment requirement, simplicity in operation and short fermentation reaction time.

Description

technical field [0001] The invention relates to the technical field of biological feed, in particular to the application of an oil-producing yeast in biological feed products. Background technique [0002] The rapid development of livestock and poultry breeding industry has put forward dual requirements of quality and quantity for the feed industry. In this process, the feed industry has also experienced a tortuous development road of encountering problems, solving problems and emerging new problems. Since the 1950s, the addition and application of antibiotics in feed has made great contributions to the development of intensive and large-scale livestock and poultry breeding. However, with the passage of time, the large and irregular use of antibiotics has led to the reduction of animal disease resistance, the increase of drug resistance of pathogenic bacteria, the emergence of drug residues in products, food safety and other problems, which seriously restricted the developm...
