ABSTRACT

Indigenous bacteria (natural bacteria) in the digestive tract of fish have more influence which helps digestion of nutrients and secrete digestive enzymes. This study aimed to isolate and selecting potentially probiotic bacteria in the digestive tract of African catfish. Selection of candidate probiotics include maksroskopik, microscopic, biochemical and pathogenicity test. The result showed 1 isolates potensif as probiotics with characteristic rounded shape of the colony, the colony edges average, average elevation, color white colonies, basil cell shape, a Gram-positive bacterium, motile, catalase negative, has an index of 2.8 and test degradative negative pathogens. From these tests grouped the isolates classified into Lactobacillus sp.
