title: [Effect of pH on the growth of Bacillus thuringiensis].
abstract: The effect of pH on the growth phase parameters was studied with Bacillus thuringiensis. The experimental data obtained were used to draw the regression equation describing the spore titre as a function of pH. As a result of analysing the equation coefficients and the effect of pH on the growth phase parameters, a pH profile has been proposed which favours an increase in the titre of spores. The profile decreases the rate of oxygen uptake at the exponential growth phase and increases the rate of accumulation of acetic acid in the growth medium with its subsequent accelerated utilization at the phase of deceleration of growth.
