Glucose repression of pigment production in atypical isolates of Aeromonas salmonicida responsible for goldfish ulcer disease.
The effect of glucose and other carbohydrates on the pigmentation of three atypical isolates of Aeromonas salmonicida indicated that the addition of D-glucose at a concentration of 0.1% (w/v) or more, inhibited pigment production and caused a reduction in the size of colonies. The addition of cAMP reversed the inhibitory effects of D-glucose on pigment production.
