Abstract
The buoyant densities of eight strains of Streptococcus mutans were determined by analytical ultracentrifugation in caesium chloride. The results were as follows (in g/cm3): K-1-R(1.7044); SL-1(1.7040); E-49(1.7010); BHT(1.7009); FA-1(1.7000); Ingbritt(1.6967); NCTC-10449(1.6964); GS-5(1.6962). These data add to the mounting evidence for genetic heterogeneity in Strept. mutans.
