Problems solved by technology

[0004] According to the above patent documents, solid-state fermentation is mostly used in the preparation of fermented feed. Although the solid-state fermentation overcomes the high cost, high environmental pollution, difficult post-processing, and cumbersome operation of machinery and equipment, etc. However, due to the addition of probiotics to mixed fermentation at the same time, if the strains are not properly selected, it is easy to cause competitive exclusion between strains, affect the complete decomposition of beneficial ingredients in fermented products, reduce the utilization rate of feed, and increase costs. And it is not conducive to the absorption of the body

Abstract

The invention discloses a probiotic agent containing Lactobacillus plantarum and Bifidobacterium lactis, and its preparing method, and belongs to the technical field of feed microbes. The probiotic agent having the advantages of special sour fragrance, high number of contained live bacteria and improved degradation rate of proteins in the soybean meal, wheat bran and corn flour is prepared through the solid-state fermentation of soybean meal, wheat bran and corn flour by adopting Lactobacillus plantarum HM-10 and Bifidobacterium lactis V9; and the method has the characteristics of low production cost and simple operation. The adoption of mixed bacterium segment solid state fermentation can utilize the mutualism synergism of strains, and can improve the yield and the thallus concentration; and the probiotic agent utilizing the growth, propagation and metabolism of the Lactobacillus plantarum HM-10 in the early stage of fermentation can provide abundant nutrients and necessary anaerobic environment for the propagation of the Bifidobacterium lactis V9, so it is helpful for the growth of the Bifidobacterium lactis V9, and the number of Lactobacillus plantarum HM-10 live bacteria is increased.

Description

technical field [0001] The invention belongs to the technical field of feed microorganisms, and relates to a probiotic agent containing plant lactobacillus and lactobacillus lactis prepared by solid-state fermentation technology using soybean meal, bran and corn flour as substrates. Background technique [0002] At present, probiotic products mostly use probiotics to directly ferment with liquid milk and soy milk to obtain functional yogurt or soy milk, and the rest are fermented in liquid state to directly collect probiotic cells and make probiotic powder, tablets or capsules. The use of liquid fermentation will produce a large amount of waste water, which will cause great environmental pollution, difficult post-treatment, and cumbersome operation of machinery and equipment. Since probiotics can improve the micro-ecological balance of the host, improve the health level of the host and live bacterial preparations and metabolites of the healthy state, the research on probioti...
