Microbial fermentation bed strain and manufacturing method thereof

Abstract

The invention discloses a microbial fermentation bed strain and a manufacturing method thereof. The microbial fermentation bed strain comprises the following components in percentage by weight: 50 to 70 percent of bacillus subtilis strain and 30 to 50 percent of saccharomyces cerevisiae. The strain adopted by the invention is safe and reliable; the production is low in cost, energy-saving and environmentally-friendly and adopts simple and controllable process; the pathogenic bacteria, parasite ova, grass seed and the like in packing can be killed; the strain can decompose livestock and poultry manure quickly, optimize breeding environment and convert the livestock and poultry manure into probiotic bacterium mycoproteins used for feeding the livestock and poultry, so the material to meat (egg) ratio is lowered effectively and breeding economic benefit is improved; and in a packing fermentation process, these kinds of bacteria have a mutually beneficial and symbiotic effect on the dynamic change of the pH value and the oxygen content, so a high constant stability is ensured in the long-term operation of the fermentation bed, and the requirement on the packing is low.

Description

technical field [0001] The invention relates to the field of microbial fermentation, in particular to a microbial fermentation bed strain and a preparation method thereof. Background technique [0002] With the development of the pig industry and the continuous expansion of the size of the pig herd, how to deal with the pollution of the environment and ecology caused by the large amount of feces and urine discharged from large-scale pig farms has become a problem that must be solved in the process of industrialization of the new countryside. [0003] Japan, South Korea and other countries have accumulated nearly 20 years of experience in the research and application of new micro-ecological active litter zero-emission healthy pig raising technology. European and American countries are actively carrying out industrialized centralized breeding production methods, and promoting new energy-saving, environmental protection and healthy pig raising technologies. [0004] By adding ...

AI Technical Summary

Problems solved by technology

However, because it is imported from Japan and requires continuous supplementation of bacteria in the feed (the vitality of the bacteria declines quickly), the price is high (up to 200 yuan / kg), farmers are unwilling to use it due to cost reasons, and the promotion of fermentation beds is slow.
