Studies on Probiotic Analysis in the Gut Region of Fresh Water Fishes in Periyar Lake, Kerala

摘要

In the present study, we isolated lactic acid bacteria (LAB) from the intestinal gut of channa (channa straita) and Tilapia (Oreochromis mossambica). The isolates were identified as lactobacilli by standard biochemical characterization. The isolated lactobacilli were if subjected to preliminary screening for various probiotic traits such as antibacterial activity Antibiotic susceptibility and auto aggregation among the several isolates. Two lactobacilli strains LAB1 and LAB 2 had promising results with higher antibacterial activity and auto aggregation property when compared to other strains of lactobacilli the result suggest that the two lactobacilli strains could be a potential candidate for a successful biological enhancer probiotic which has antagonistic property against human pathogen.
