Coaggregation and autoaggregation properties in lactic acid bacteria

Lactic acid bacteria are the normal flora of the gastrointestinal system of the human organism. They can prevent pathogenic bacteria from settling in the intestinal epithelium by colonizing it. Lactic acid and acetic acid formed as a result of fermentation lower the pH of the environment and prevent the growth of pathogenic bacteria. Bacterial aggregation and autoaggregation properties of lactic acid bacteria strains isolated from colostrum were carried out. Autoaggregation values of lactobacillus strains were evaluated between 3-19%. Coaggregation values of lactobacillus strains with E.coli ATTC 35298 were determined between 34-88%. Coaggregation properties of lactobacillus strains with S.aureus ATCC 25923 were evaluated between 27-37%. Keywords: Lactic acid bacteria, probiotics, autoaggregation, coaggregation, normal flora
