Abstract
The distribution of total hectrotrophic bacteria (THB) and lipolytic bacteria in
various regions (body surface, gill, intestine and flesh) of fish Etroplus suratensis (Bloch)
during storage at 28 + 2°C and 4 °C was studied. Pseudomonas dominated at reduced
temperature whereas at 28 + 2°C and in fresh condition Vibrio, Aeromonas, and
Acinetobacter dominated. Lipolytic activity was elaborated by the members of
various genera and their activity varied in different lipid compounds (t~ib~tyrin, tw~en
80, tween 60, tween 40 and tween 20). Tributyrin was utilized by maJonty of the is~lates.
AH the selected isolates preferred a temperature of 35°C and pH 6.0 for their
maximum growth. Aeromonas and Vibrio showed maximum growth at 0.5 % Na CJ
concentration while 3 % NaCl was found to be optimum for Pseudomonas
