Compound microbial preparation and culture method and application thereof

Abstract

The invention relates to the technical field of microbial culture, and in particular to a compound microbial preparation and a culture method and application thereof. The culture method includes: adopting a mixed culture technology, respectively subjecting Lactobacillus acidophilus, Lactobacillus plantarum, Bifidobacterium bifidum, Bacillus subtilis, Bacillus licheniformis, Rhodopseudomonas palustris, Saccharomyces cerevisiae and Candida utilis strains to activation, liquid strain cultivation, composite strain cultivation and finished product cultivation to obtain the compound microbial preparation. The preparation can be used for pig breeding, and has effects of promoting growth, helping digestion, resisting diseases, increasing animal body weight and reducing feed consumption. The methodimproves biomass and physiological metabolic function of microorganisms, makes up for shortcomings of independent culture, uses symbiosis, partial symbiosis, etc. to promote growth of compound microorganisms, and has many obvious advantages compared with a traditional pure culture technology.

Description

technical field [0001] The invention relates to the technical field of microorganism cultivation, in particular to a compound microorganism preparation and its cultivation method and application. Background technique [0002] Mixed culture refers to the culture of two or more microorganisms, which is a new development of pure culture technology and a new culture technology that does not require complicated DNA recombination in vitro but can achieve similar effects. The use of microorganisms by humans has gone through two stages: natural mixed culture and pure culture. Pure culture enables researchers to get rid of the complicated situation of coexistence of multiple microorganisms, and can study single-purpose strains without interference, thus enriching our understanding of microorganisms. Knowledge of morphological structure, physiological and genetic traits. However, in the long-term experiment and production practice, people have found that many important biochemical pr...

Problems solved by technology

However, in long-term experiments and production practices, people have found that many important biochemical processes cannot be completed by a single microorganism or can only be carried out weakly, and must be completed by co-cultivation of two or more microorganisms.
