dc.description.abstractThe influence of environmental factors on the growth of Aeromonas hydrophila was investigated Four isolates (AH 37, AH 79, AH 86 and AH 100) were exposed to various environmental factors such as pH, salt concentration and temperature in laboratory condition. All the four isolates showed more or less similar growth at pH 7.0, 8.0 and 9.0 at 30 degrees C and 5 degrees C. At pH 5.0, 6.0 and 10.0, the log number of cells was found to be lesser than that of pH 7.0, 8.0 and 9.0 at both 30 degrees C and 5 degrees C. The results of the influence of salt concentration on the growth of Aeromonas hydrophila revealed that NaCl concentration of 0.5%, 1.0% and 2.0% favored the growth of this organism at both 30 degrees C and 5 degrees C. Increase in the salt concentration resulted in the growth of the decrease of this organism. Three percentages and 4% salt concentration moderately supported the growth of the organisms in the medium whereas at 5.0% NaCl concentration, there was no growth. Moderate growth of A. hydrophila at 5 degrees C is an interesting observation. The ability to grow at salt concentration between 0.5%, 4.0% under acidic and alkaline conditions pose a problem in the preservation of seafoods. These criteria may account for modified preservation techniques.en_US
