Phenotype and genotype of  lactic acid bacteria (LAB) isolated from the tiger grouper Epinephelus fuscoguttatus alimentary tract.

ABSTRACT: Lactic acid bacteria (LAB) have been isolated successfully from the tiger grouper Epinephelusfuscoguttatus intestine. However, their genus or species have not been identified. Therefore, the objective of the present study was to characterize the three isolated LAB (KSBU-12C, KSBU-5Da, and KSBU-9) based on their phenotype and genotype. The LAB phenotype was examined by observing morphological features including cell morphology, spore production and motility. The physiological tests were performed in 6.5% NaCl at the  temperatures of 10 ^oC and 45 ^oC, and the biochemical tests were evaluated based on the production of enzymes catalase, oxidase and arginine dehydrolase, following  the Standard Analytical Profile Index, API 50 CH kit.  The genotype was examin
