Induction of L-asparaginase synthesis in Vibrio proteus.
Studies on L-asparaginase synthesis in V. proteus showed increased synthesis in cultures grown under conditions of moderate aeration (P less than 0.005) after oxygen had been used up from the medium. Addition of sodium lactate to the medium at a concentration of 80 mu mole/ml, stimulated L-asparaginase synthesis (2.2 times over control) in moderately-aerated cultures (P less than 0.001). The substrate L-asparagine induced enzyme synthesis when growth conditions were made anaerobic or lactate was incorporated into the medium (3.8 times increased enzyme synthesis over control).
