Triclosan inhibition of membrane enzymes and glycolysis of Streptococcus mutans in suspensions and biofilms.

Triclosan was found to be a potent inhibitor of the F(H+)-ATPase of the oral pathogen Streptococcus mutans and to increase proton permeabilities of intact cells. Moreover, it acted additively with weak-acid transmembrane proton carriers, such as fluoride or sorbate, to sensitize glycolysis to acid inhibition. Even at neutral pH, triclosan could inhibit glycolysis more directly as an irreversible inhibitor of the glycolytic enzymes pyruvate kinase, lactic dehydro genase, aldolase, and the phosphoenolpyruvate:sugar phosphotransferase system (PTS).
