Biofilm Morphology and Effects of Bacterial Cell-to-Cell Communication on Biofilm Formation by Escherichia coli K-12

摘要

The study describes the morphology of biofilms formed by two E. coli K-12 strains as shown by reflected light microscopy and the dynamics of the bacteria-substrate contact during cultivation in liquid medium as registered by plasmon microscopy. The effects of quorum sensing on E. coli K-12 biofilm formation is also examined. Quorum sensing influences biofilm growth but has no apparent effects on initial attachment of bacteria.
