title: Effect of variation in growth conditions on the activity of dextranase inhibitor in continuous cultures of Streptococcus sobrinus.
abstract: 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.
