Project description:Investigation of whole genome gene expression level changes in a Escherichia coli MG1655 K-12 ∆fnr mutant, compared to the wild-type strain. The mutations engineered into this strain produce a strain lacking the FNR protein.
Project description:To investigate the regulatory targets of the RegR virulence regulon of rabbit specific enteropathogenic Escherichia coli strain E22
Project description:The purpose of this study is to determine whether the presence of pathogenic Escherichia coli in colon is associated with psychiatric disorders.
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:In this study, we carried out genome-scale CRISPRi modulation combining fluorescence-activated cell sorting (FACS) and next-generation sequencing (NGS) to identify genetic determinants for FFAs overproduction in Escherichia coli. The pcnBi (AP) strain that repressed the expression of pcnB produced 2992 mg l FFAs, which was 4.0-fold of the CF (A) strain. To analyze the underlying mechanism of FFAs overproduction, the engineered strain pcnBi and the control strain CF were applied to the transcriptomic and proteomic analyses.
Project description:Avian pathogenic Escherichia coli strains frequently cause extra-intestinal infections and are responsible for significant economic losses in the poultry industry worldwide. APEC isolates are closely related to human extraintestinal pathogenic E.coli strains and may also act as pathogens for humans. In this work, three type VI secretion systems were deleted to analyze which pathogenicity characteristics would change in the mutants, compared to wild type strain (SEPT 362).
Project description:Here, we treated Escherichia coli strain TO114 expressing a halotolerant cyanobacterium Halothece sp. PCC7418-derived NhaC Na+/H+ antiporter (H2569) with salt stress (0.4 M NaCl) and performed RNA sequencing analysis.
Project description:An experiment to identify the downstream targets of PatE, a prophage encoded AraC-like transcriptional regulator, in transcriptional activation of acid-resistance pathways of enterohemorrhagic Escherichia coli strain EDL933 using deletion and complementation strains (Delta3 and Delta3_1, respectively).
