Deterination of Some Properties of Lactobacillus Strains Isolated from Cecum

Abstract

T Some properties o antibacterial activit and proteolytic acti less lactic acid tha levels. It was foun Lactobacillus strai tal number of 36 Lactobacillus strains were isolated and identified from cecum in our previous study. those strains were determined, These properties were lactic acid production, proteolytic activity and against pathogens. It was determined that lactic acid productions ranged from 2.200 to 6,800 mg/ml, ity ranged between 0.013 and 8.600 mg tyrosine/5 ml. Strains with high proteolytic activity produced the others. Beyond that 25 strains inhibited E. coli K12 107 and S. typhimurium 60-62 at different that S. typhimurium 60-62 was inhibited more than was E. coli K12 107, and the most effective s were L. fermentum KY2002 and L. plantarum KY2402.
