Kn. Majeed et Ic. Macrae, EFFECT OF PH LEVEL ON THE GROWTH AND EXOTOXIN PRODUCTION BY AEROMONASAT REFRIGERATION TEMPERATURE, Microbios, 73(297), 1993, pp. 281-288
The effect of the starting pH of two media (a sterile meat extract and
tryptone soy broth yeast extract) on the growth and production of exo
toxins and exoenzymes by an Aeromonas hydrophila strain at low tempera
ture was investigated. The results showed that the strain grew readily
in the two media within a wide range of starting pHs at 5-degrees-C.
Optimal growth as well as optimal production of exotoxins and exoenzym
es were found to require slightly alkaline initial pH of the medium. T
he range of known biological properties of Aeromonas exotoxins and exo
enzymes has been extended.
