Temporal gene-expression in Escherichia coli K-12 biofilms.

Domka Joanna J Lee Jintae J Bansal Tarun T Wood Thomas K TK

Environmental microbiology 20070201 2

Analysis of the temporal development of Escherichia coli K-12 biofilms in complex medium indicates the greatest differential gene expression between biofilm and suspension cells occurred in young biofilms at 4 and 7 h (versus 15 and 24 h). The main classes of genes differentially expressed (biofilm versus biofilm and biofilm versus suspension cells) include 42 related to stress response (e.g. cspABFGI), 66 related to quorum sensing (e.g. ydgG, gadABC, hdeABD), 20 related to motility (e.g. flgBCE ...[more]

Project description:For the microarray experiments, 10 g glass wool (Corning Glass Works, Corning, N.Y.) were used to form biofilms (30) in 250 mL in 1 L Erlenmeyer shake flasks which were inoculated with overnight cultures diluted that were 1:167. The cells were shaken at 250 rpm and 37°C for 24 hours to form biofilms on the glass wool, and RNA was isolated from the suspension cells and the biofilm. Keywords: E. coli biofilm
