[Autostabilization of the pH in a batch culture of Pseudomonas]

Ranges within which the pH of the environment can be self-regulated have been determined for microorganisms belonging to the Pseudomonas genus. The ability of these microorganisms to self-regulate the pH was detected both at an increase and a decrease in the pH of the environment as compared to its optimal value. The rate of self-regulation appears to be proportional to the concentration of viable cells in a suspension. The results may be used for creating an economical system for maintaining the pH of the environment in industrial fermentation.
