Role of D‐alanylation of <i>Streptococcus mutans</i> lipoteichoic acid in interspecies competitiveness

Abstract

D-Alanylation is involved in interspecies competitiveness of S. mutans within oral biofilm by regulating mutacins and lactic acid production, which may modulate the profiles of dental biofilms. Results provide new insights into dental caries prevention and treatment.
