Abstract:
Objective:To study the effect of extraneous sugar on rea ct ive oxygen species metabolism of Streptococcus mutans. Methods: Electron spin resonance (ESR) method was used to measure reactive oxygen spe cies of Streptococcus mutans incubated in the different sugar incubation con ditions. Results:With the increase of glucose at 0.0062~0.05 mo l/L, the quantities of reactive oxygen species produced by Streptococcus mutan s increased and increased to the maximum when Streptococcus mutans were in cubated in different sugar culture fluids within 2 h. All kinds of sugar promote d reactive oxygen species metabolism of Streptococcus mutans. Conclu sion:Extraneous sugar promotes reactive oxygen species metabolism of Streptococcus mutans.
