Inhibition Effect of Extract from Auricularia auricular on Quorum Sensing and Biofilm Formation of Bacteria

doi:10.7506/spkx1002-6630-201009033

Abstract

Abstract:

Methanol-soluble compounds were extracted from Auricularia auricular to investigate the inhibition effect on quorum sensing through agar plate assays. The inhibition effect of extract from Auricularia auricular on biofilm formation of Escherichia coli 8099 was evaluated through ninety-six-well plate biofilm assay and disk reactor biofilm experiments. Approximately 72.16% inhibition rate on biofilm formation was observed in Auricularia auricular extract at the concentration of 0.3 g/mL.

Key words: quorum sensing, Auricularia auricular, biofilm, inhibition

CLC Number:

TS201.3
