摘要：Bekasam is well known in Indonesia as one of fermented fish product. Several fermented products generate lactic acid bacteria (LAB) which h as probiotic potential with beneficial effect s on human health . However, In Indonesia, the research on LAB isolated from fermented fish product , including bekasam , is still rarely conducted . The aim of this study was to evaluate the probiotic potential of LAB isolated from bekasam . Two LAB isolat e s namely NS ( 5 ) and NS ( 6 ) were selected based on the ir resistance to gastric pH ( pH 2.0 ), intestinal pH ( pH 7.2 ) and bile salt s ( 0.5% oxga l). P athogenic test , antimicrobial activity test , characterization and identification of the isolats were also performed respectively. The result showed that NS(5) isolat e survived at pH 2 .0, pH 7 . 2 and bile salts (oxgal ). It was obtained that NS(5) isolat e was non pathogenic bacteria which exhibited antimicrobial activity against Salmonella Typhimurium ATCC 14028 and Escherichia coli. The characterization result showed that NS(5) isolat e was Gram-positive bacteria, rod-shaped , non-endospore producer, negative catalase, homofermentative, non motile, having an amilolitik as well as lipolitik activity and able to grow at 30 - 37°C, NaCl 2-7% dan pH 4.4-9.6. Isolate NS(5) isolate was then identified as Lactobacillus plantarum 1 strain with 99.9% of similarity. Meanwhile , NS(6) isolate was not able to survive in the medium containing bile salts (oxgal), therefore it was not categorized as a probiotic candidate.
