Enhanced fermentation bed composite strain

Abstract

The invention discloses an enhanced fermentation bed composite strain. The enhanced fermentation bed composite strain comprises, by weight, 5-20% of lactic acid bacteria, 10-50% of Bacillus subtilis, 30-70% of Candida utilis and 5-15% of an assistant. A dry strain is produced through seed selection, breeding, spawn preparation and dehydration drying, and is used in fermentation bed culture. A general EM bacterial liquid fermentation strain in the market undergoes formula improvement, and freeze drying and vacuum packaging preservation are carried out, so the problems of low strain activity, easy bed dyeing, long operation time and poor meat in the fermentation bed culture process are effectively solved, and a fermentation bed produced by using the strain disclosed in the invention has high living bacterium rate and is convenient to manage.

Description

【Technical field】 [0001] The invention relates to the field of microbial fermentation, in particular to a composite bacterial strain of a microbial fermentation bed. . 【Background technique】 [0002] In the large-scale breeding industry, how to deal with the pollution of the ecological environment caused by the large amount of feces excreted by livestock, and effectively prevent various infectious diseases caused by the growth of bacteria are the problems that the breeding industry needs to solve urgently. [0003] The main components of animal manure are 3 / 4 water and 1 / 4 solid, 30% of the solid is dead bacteria, 10% to 20% is fat, 2% to 3% is protein, and 10% to 20% is inorganic salt , 30% are undigested residual food and solid components in digestive juice such as exfoliated epithelial cells. The main components of fecal odor are: ammonia, volatile fatty acids (mainly acetic acid, propionic acid, butyric acid, formic acid), volatile sulfur compounds such as hydrogen sul...

AI Technical Summary

Problems solved by technology

Therefore, when using EM bacteria liquid strains, it is necessary to frequently maintain and replace the cushion layer, which is complicated and requires a lot of work.

[0009] At present, most of the fermentation bed strains are Bacillus subtilis and Saccharomyces cerevisiae. For example, Chinese patent CN101948754 A discloses microbial fermentation bed strains and a production method thereof, but the Saccharomyces cerevisiae vitamin content is not high, and The corresponding nutrient solution, growth factors and trace elements are not added to the strain, so the survival rate of the strain cannot be guaranteed, and the fecal excrement can still be effectively decomposed after being inoculated into the fermentation bed

Chinese patent CN105385612 A discloses a beneficial bacterial component for adding to feed: composed of Candida utilis, Bacillus licheniformis, and Lactobacillus plantarum, but the Bacillus licheniformis that it adopts is not as resistant to high temperature as Bacillus subtilis. When the fermentation bed is abnormal, the reproduction cannot be resumed quickly, which provides a more suitable anaerobic environment for the growth of microorganisms, especially lactic acid bacteria bifidobacteria, thereby affecting the growth of beneficial bacteria
