Abstract excerpt
The physiological and biochemical characterization of Streptococcus salivarius mutants isolated by positive selection for resistance to 0.5 mM 2-deoxyglucose in the presence of lactose are reported. We found 2 classes of mutants following a series of experiments that included: growth rate determinations, uptake studies, measurement of phosphotransferase system (PTS) activities and detection of the IIIman proteins...
