Antimicrobial Activities of Lactic Acid Bacteria Strains Isolated from Nile Tilapia Intestine (Oreochromis niloticus)

Ana A Zapata, Maurilio Lara-Flores

Abstract


The intestinal microflora of Nile tilapia (Oreochromis niloticus) fish was studied to isolate and identify lactic acid bacteria as new probiotic. A total of five lactic acid bacteria were isolated from intestine to evaluate with antibacterial properties. These strains were identified by conventional and molecular techniques as: Enterococcus faecium, Leuconostocmesenteroides, Lactobacillus fermentum, Lactobacillus plantarum, Enterococcus durans. Leuc.mesenteroides present more ability to inhibit growth of fish pathogens bacteria and selected as possible probiotic bacteria to use in aquaculture.
