title: D-lactate production and [14C]succinic acid uptake by adherent and nonadherent Escherichia coli.
abstract: Escherichia coli isolates of different adherence phenotypes produced different amounts of D-lactate. Alterations of culture conditions did not influence the amount of D-lactate produced. The observed pH decreases in tissue culture medium corresponded with increases in D-lactate concentration. Very little [14C]succinic acid was incorporated into cells during the in vitro incubation of adherent and nonadherent E. coli with HeLa cells, but the amounts of tracer removed from the culture medium by adherent and nonadherent strains differed. The results are further evidence of a difference in the metabolic behavior of adherent and nonadherent E. coli.
