Abstract:
Objective:To investigate the inhibition of Streptococcus oligofermentans(So)on Streptococcus mutans(Sm)and the hydro-gen peroxide(H2 O2 )producibility by So under different sucrose concentration environment.Methods:The inhibition of So on Sm was observed by plating method under different sucrose concentration environment.The initial synthesis rates and production of H2 O2 by So were determined by 4-aminoantipyine-horseradish peroxidase method.Results:Under 500 mmol/L of H2 O2 ,the inhibition of So on Sm was not observed.Under the other sucrose concentration environment,the inhibition of So on Sm was as following:50 mmol/L >0 mmol/L and 1 mmol/L(P <0.05);the initial synthesis rates of H2 O2 by So under different sucrose concentrations were as following:50 mmol/L >0 mmol/L and 1 mmol/L >500 mmol/L(P <0.05);the total production of H2 O2 by So:0 mmol/L and 1 mmol/L >50 mmol/L >500 mmol/L(P <0.05).When So was inoculated before Sm,the inhibition of So on Sm was stronger than that when the two species were inoculated at the same time.Conclusion:The capability of the inhibition of So on Sm and the production of H2 O2 by So are influenced by sucrose concentration.
