Abstract

Aerotolerance in the growth of Streptococcus mutans and related streptococci was examined under glucose-limited conditions. The growth rate of all strains tested was more or less retarded when they were transferred from anaerobic to aerobic conditions. As for growth yield, however, some strains (group 1) showed reduced values for the increment of cellular dry weight change (in grams per mole of glucose), whereas others showed either unaltered (group 2) or increased (group 3) yields. The characteristic feature of strains in groups 2 and 3 was their high activity of both glucose- and pyruvate-dependent oxygen uptake when strains were grown under aerobic conditions. By contrast, the activity of pyruvate-dependent oxygen uptake by group 1 strains was negligibly low, whether grown under aerobic or anaerobic conditions. Some strains (group 1a) consumed oxygen in the presence of glucose at a much faster rate than others did (group 1b). There seems to be a good correspondence of these aerotolerance groupings to those based on serotypes of S. mutans. Thus, the groups 1a, 1b, 2, and 3 correspond to serotypes g, a+d, c+f, and b, respectively.
