antimicrobial substances produced by lactic acid bacteria are mostly

Lactic acid bacteria produce antimicrobial substances are peptides or proteins, called bacteriocins. They can be two types of bacteria secrete hormone, a class is only the inhibition of the related bacteria, antibacterial spectrum is narrow, can hinder contact with pathogenic microorganisms intestinal cells; another with broad-spectrum antimicrobial activity against pathogens such as they are: Salmonella, congratulations coli and Pseudomonas has good inhibition. Therefore, the long-term lactic acid in the diet can reduce the breeding animals add enteritis and other diseases.
Lactic acid bacteria, bacteria growth and lactic acid powder animals produce beneficial nutrients, such as lactic acid, amino acids, vitamins, enzymes and antibacterial substances. In the feed additive, both antiseptic effect, increased feed flavor, promote aquaculture animal appetite.
