Abstract
Growth pattern of Vibrio parahaemolyticus, V. vulnificus, V. alginolyticus, V. mimicus and V. harveyi, isolated from fish from the Arabian sea off Cochin was studied at 4, 15, 28+/-2 (room temperature), 37 and 42degree celcius in Trypticase Soy Broth with 3% NaCl. Optimal temperature for the growth of all species was 37degree celcius V. parahaemolyticus and V. alginolyticus exhibited growth at 42degree celcius also. All the species studied grew slowly at 15degree celcius , but failed to grow at 4degree celcius. Twenty important biochemical reactions were also studied at the above temperatures. Observations of the biochemical activity where in accordance with the growth except at 15degree celcius where, although there was growth, most of the biochemical reactions gave negative results.
