Abstract:
Objective To investigate the bacteriostatic effect of starch-based alkyl poly glycoside(APG).Methods The nutrient broth dilution method was used to investigate the inhibiting effect of C8-10,C12 and pilot product C12 APG to the E.coli and Staphylococcus aureus.Results Determination of antibacterial fluid absorption was performed after 24 h-reaction.The MIC of C12,pilot product C12 and C8-10 were 0.03125,0.25 and 0.0156 g/ml for the E.coli;and were 0.062 5,0.25 and 0.062 5 g/ml for Staphylococcus aureus.Based on bacterial culture counts,at the APG concentration of MIC or higher than the MIC,the inhibitory rate of bacteria was more than 99%,the bacteriostatic effect was accorded with the absorbance.Conclusion Starch-based APG may have some antibacterial effects.
