Abstract

Abstract:

The inhibition effect of Auricularia auricula extract on the biofilm formation of Escherichia coli 8099 was investigated using Calgary biofilm device and colony count method. Meanwhile, the morphology and structure of E. coli biofilm were also examined using optical microscope and confocal laser scanning microscope after treatment of Auricularia auricula extract. The results indicated 0.3 g/mL of Auricularia auricula extract obviously inhibited the biofilm formation of E. coli and the inhibition rate reached up to 73.0%.

Key words: Auricularia auricula, Escherichia coli, biofilm, inhibition

CLC Number:

TS201.3
