Effect of variation in growth conditions on the activity of dextranase inhibitor in continuous cultures of Streptococcus sobrinus.
The activity of free extracellular dextranase inhibitor was determined in strains of Streptococcus sobrinus which were grown in a chemostat under a variety of defined conditions. Maximum release of dextranase inhibitor occurred at low growth rate in glucose-limited medium at pH 6.5. Free inhibitor could not be detected when the strains were grown at high growth rate or in batch culture.
