It was shown that lactic acid bacteria isolated from different sources produced along with lactic acid the bacteriocine substances. Strains producing bacteriocines were mainly isolated from digestive tract of people and calves. Bacteriogenic properties have been shown more frequently in the case of lactobacilli (7.8%) more rarely--in coccoid forms of lactic acid bacteria (4.5%). At the same time bacteriocine activity was higher in the case of Enterococcus and depended both on the strain type and cultivation conditions. Synthesis of bacteriocines started from the hours of phase of the culture growth and reached maximum at the beginning of stationary phase. The bacteriocine accumulation rate depended on composition of the growth medium.
