Abstract:
To investigate the effect of casein phosphopeptide-amorphic calcium phosphate(CPP-ACP) on the growth of Lactobacillus fermentum and to evaluate the possibility of CPP-ACP as a biological anticariogenic agent. Lactobacillus fermentum was inoculated in BHI with different concentrations of CPP-ACP and grew in anaerobic condition at 37 ℃ for 48 h. Used MTT method to evaluate the effects of CPP-ACP on the growth of Lactobacillus fermentum. CPP-ACP inhibited the growth of Lactobacillus fermentum effectively. With the concentration of CPP-ACP increasing, the values of A(550 nm) decreased. It was found that CPP-ACP had inhibitory effect on the growth of Lactobacillus fermentum, the inhibitory effect increased with CPP-ACP concentration.
