Preparation method for fermenting and producing bacteriocin rice feed rich in taurine

Abstract

The present invention discloses a preparation method of a taurine enriched microorganism peptide rice feed produced by a fermentation and relates to the technical field of agriculture and animal husbandry. The preparation method is as follows: a potato culture medium is prepared and microorganism strains are activated and cultured; rice, bran, soybean meal, cysteine and methionine are weighed, the weighed materials are stirred and mixed evenly, the mixture is subjected to a high temperature steam sterilization, the sterilized mixture is cooled to obtain solid fermentation products, a seed microorganism suspension is inoculated into the sterilized solid fermentation products, then water is added, the materials are stirred evenly, and then the stirred materials are cultured in a solid state fermentation tank to obtain the taurine enriched microorganism peptide rice feed. Yeast S-78 converts starch into monosaccharide to provide carbon sources for the fermentation. Aspergillus niger PL-39 produces protease, amylase, pectinase, and organic acids such as citric acids and gluconic acids. The three microorganisms react together to produce various enzymes, degrade rice, soybean meal and bran in the fermentation and produces the taurine enriched microorganism peptide rice feed by combing the cysteine and methionine.

Description

Technical field: [0001] The invention relates to a preparation method for fermenting and producing bacteriocin rice feed rich in taurine, and belongs to the technical field of agriculture and animal husbandry. Background technique: [0002] With the rapid development of my country's feed industry, the prices of conventional protein raw materials such as soybean meal and fish meal continue to rise, the cost of feed increases sharply, and the income of breeding continues to decrease. How to reasonably and effectively use unconventional protein feed resources to replace conventional protein feeds such as soybean meal or fish meal to reduce feed costs has become a market concern. As a major rice producing province, our province produced 11.9845 million tons of rice in 2013, a year-on-year increase of 1.37%. In addition to supplying people's daily dietary needs, these rices still have a large proportion of rice used as raw materials for industrial fermentation and starch sugar p...
