Project description:The changes in protein composition of E. coli were studied in a global proteomic approach for aerobic growth without or with fumarate as carbon source (glycerol + O2, fumarate + O2, respectively) and anaerobic growth without or with fumarate as carbon source (glycerol + DMSO, glycerol + DMSO + fumarate, respectively). The experiments should unravel the changes in response to fumarate under aerobic (i) and anaerobic (ii) conditions, and more generally (iii) the fumarate proteome under aerobic versus anaerobic conditions. Fumarate was used as the C4DC due to its capability to support aerobic and anaerobic growth, and glycerol was used as the alternative carbon source that exerts no or only weak carbon catabolite repression.

Project description:M9 glucose minimum media were analyzed for RNA expression. We use this expression information to show that mRNA level correlate with codon efficiency (Boel et al., Nature 2015)
Project description:Transcriptional profiling of E. coli MG1655 to Trimethoprim in i) LB media, ii) M9 minimal media and iii) M9 minimal media with supplements to study the association of gene expression with corresponding lethal and non-lethal growth conditions. Supplementation conditions in M9 media included addition of 50 microgram/ml of adenine, methionine, glycine or thymine in various combinations.
