Abstract
One of core relationships between microorganisms in nature are antagonistic relationships, i.e. one type of bacteria inhibit the living ability of another species. There are various forms of specific and nonspecific antagonism associated with competition for nutrients, release of constructive and energy metabolism substances, bacteriocins, antibiotics, etc., which is widely used in medical practice, agriculture, and food industry. The food industry and especially the cheese-making, is constantly exposed by risks from pathogenic, opportunistic, and harmful microorganisms. The careful selection of industrial strains of microorganisms which can be used in bacterial starter cultures and drugs will significantly reduce these risks. It is well known that lactic acid bacteria have pronounced antagonistic activity to extraneous microflora. These bacteria include the mesophilic lactic acid bacillus called Lactobacillus plantarum.
The article presents our results on the research of antagonistic activity of mesophilic lactic acid bacilli Lactobacillus plantarum to identify strains with maximum antagonizing activity towards strains of colibacillus bacteria, for their further use in bacterial concentrates for special purposes.
Key words: Antagonistic activities, Lactobacillus plantarum , Culture test, Escherichia coli.
