<![CDATA[Lactic acid bacteria (LAB) is a generic term for bacteria that ferment lactose and produce lactic acid as its main product. In general, lactic acid bacteria belonging to Gram positive bacteria, negative catalase, does not form spores, have no cytochrome, aerotolerant, anaerobic to microaerophilic, require complex nutrients such as amino acids, vitamins (B1, B6, B12 and biotin), purine, pyrimidine. This study aims to determine the species of lactic acid bacteria (LAB) from isolate SR13 isolated from rumen liquid of bali cattle. The identification was started by cultivation of isolate on de Man, Rogosa, Sharpe (MRS) medium with anaerobic condition, confirmation of isolates by Gram staining and catalase test, and finally identificion of species by using conventional test and 50CH API test kit. The results of study showed, the isolate of LAB SR 13 was detected asPediococcus/Enterococcus, moreover, identification by using 50CH Api test kit showed as Pediococcus pentosaceus 2]]>
