Project description:This Series involves two studies: 1) The gene expression of E. coli K-12 BW25113 ompA mutant strain vs. wild type strain glasswool biofilm cells and E. coli K-12 BW25113 ompA mutant vs. wild type polystyrene biofilm cells. 2) The gene expression of E. coli BW25113 ompA/pCA24N_ompA vs. ompA/pCA24N suspension cells.
Project description:Escherichia coli K-12 BW25113 were cultured in the LB and M63 media. Exponetially growing populations were collected for RNAseq. The culture medium-induced transcriptional changes were analyzed.

Strains: E. coli K-12 BW25113 wild type, ompA mutant Medium: LB Cell type: Biofilm cells grown on glasswool and polystyrene surfaces Time: 15 h Temperature: 37C Strains: BW25113 ompA/pCA24N_ompA and ompA/pCA24N Medium: LB Time: 7 h Temperature: 37C Cell type: suspension cells, induced by 0.1 mM IPTG
Project description:Transcripitonal profiling of Escherichia coli K-12 BW25113 comparing cells with isooctane treatment at time point of 0, 10, 30 and 60 min with two biological replicates
Project description:The stress effect of 100 uM sodium tetrachloropalladate (II) was evaluated in Escherichia coli K-12 BW25113 strain on the transcriptome level
Project description:Expression profile of E. coli BW25113 grown under standard laboratory atmosphere with a fine particulate matter (PM2.5) concentration of 17 mg m-3, under urban polluted atmosphere with a PM2.5 of 230 mg m-3 or under diesel exhaust atmosphere with a PM2.5 of 613 mg m-3. Expression profile of the diesel exhaust atmosphere-adapted E. coli strain T56-1 grown under diesel exhaust atmosphere.
Project description:RpoS, an alternative sigma factor, is critical for stress response in Escherichia coli.RpoS also acts as a global regulator for stress control of gene expression, and actually dose so in log stage and stationary stage. To further understand the effect of environmental stresses on in ethanologenic strains, DNA microarrys was used to analyze the expression profiles of E. coli and its rpoS mutant strain. BW25113（rpoS-）and BW25113 were selected at log stages and stationary stage of early development for RNA extraction and hybridization on Affymetrix microarrays. To that end, we hand-selected BW25113 and BW25113（rpoS-） according at different treatments: BW25113（rpoS-）at log stage (BW25113(rpoS-) log), BW25113 at log stage (BW25113 log),BW25113（rpoS-）atstationary stage ( BW25113(rpoS-) stationary), BW25113 at stationary stage ( BW25113 stationary)
