The LAB isolates were analyzed for their genomic fingerprint profile using repetitive-element based PCR (rep-PCR) technique. A primer targeted for the tri-nucleotide repeat (GTG)5 (5' GTGGTGGTGGTGGTG 3') was used (2). The amplification reactions were carried out in 25 μl reaction volume, using Takara Ex Taq DNA polymerase and buffer system (Takara Bio Inc., Japan). The final PCR mixture comprised of 1x Ex Taq buffer, 200 μM of each deoxynucleoside triphosphate, 800 nM
primer, 1.25 units of Ex Taq DNA polymerase, and 2 μl of the
