Description
Summary:The aim of this study was to identify the genetic diversity of lactic acid bacteria (LAB) isolated from the local goat's milk. A total of 100 raw milk samples were collected from the different Basrah local markets. All the samples were cultured in the De man, Rogosa, and Sharpe <strong>(</strong>MRS) medium which enhances the growth of lactic acid bacteria. The result of the study showed that the only 64 lactic acid bacteria isolated gave the Gram-positive and catalase-negative were 64 (64%). All the suspected isolates were detected and identified by using polymerase chain reaction (PCR) targeting the 16S rRNA gene and DNA sequencing. The sequencing results showed that 9 strains belong to <em>Lactococcus</em> spp. and 6 strainsbelongto<em> Lactobacillus</em> spp. and all tested isolates had similarity over 99% with those recorded in the GenBank of The National Centre for Biotechnology.
