The Growth of Streptococcus mutans and Streptococcus sanguis in Binary Continuous Culture

Abstract

This investigation has provided evidence supporting the existence of bilateral antagonism between Streptococcus mutans, strain 6715-15 and Streptococcus sanguis, strain 10558. The antagonistic effect is a function of the growth rate of the organisms and can not be demonstrated in culture filtrates. The original model of simple competition for a growth-limiting substrate proposed in this thesis does not apply to S. mutans and S. sanguis under the conditions used.
