EVALUATION OF PROBIOTIC POTENTIAL OF LACTOBACILLUS FERMENTUM STRAIN Research Article

In present study, milk samples were collected from different regions of Jodhpur. Lactobacillus strains were isolated on MRS agar medium. Several biochemical and physiological tests were performed for identification of these isolates. The isolates were screened for their antimicrobial activity against some human pathogenic bacteria by using agar well diffusion method. One of the isolates with significant antagonistic property against some Gram positive and Gram negative human pathogens was found to be Lactobacillus fermentum. The 16s rRNA sequence of this isolate was done and the sequence was submitted in the NCBI Genbank database. From all the results it is concluded that the isolate was L. fermentum with significant probiotic potential.
