additional information in an enzyme disruption mutant, the highest concentration of H2O2 attained in the medium is found to be approximately 1 mM, about one-fifth the level for the parental strain. Although cell growth continuous until glucose in the medium becomes undetectable even in the absence of added catalase, the maximum cell mass attained is considerably higher in the presence of catalase than in its absence. The maximum cell mass achieved in the presence of added catalase is reproducibly lower by 0.2 to 0.3 turbidity units than that of the parent Streptococcus pneumoniae

additional information Streptococcus pneumoniae energy-yielding metabolism can be described as follows: as long as glucose is available, approximatelyone-fourth of the pyruvate formed is converted to acetate by the sequential action of pyruvate oxidase and acetate kinase with acquisition of additional ATP. The rest of the pyruvate is reduced by lactate dehydrogenase to form lactate, with partial achievement of redox balance. The lactate is oxidized by lactate oxidase back to pyruvate, which is converted to acetate as described above; and the sequential reactions mentioned above continue to occur as long as lactate is present ?
