Escherichia coliis both a harmless commensal in the intestines of many mammals, as well as a dangerous pathogen. The evolutionary paths taken by strains of this species in the commensal-to-pathogen transition are complex and can involve changes both in the core genome, as well in the pan-geno...
Escherichia coli is a Gram-negative rod that is a member of the family Enterobacteriaceae. It is oxidase-negative and grows using simple carbon sources, including glucose and acetate. The hexose is fermented to a mixture of acids (lactate, acetate, and formate) as well as carbon dioxide. ...

Flow cytometry revealed that DH5α and EHEC OMVs increased aneuploidy in p53 mutant Caco-2 cells, but not in p53 wild type LoVo cells. Conclusion We conclude that E. coli derived OMVs, whether from avirulent or pathogenic strains are potentially genotoxic....
Cultivation of Escherichia coli harbouring heterologous genes of oligosaccharide synthesis is presented as a new method for preparing large quantities of high-value oligosaccharides. To test the feasibility of this method, we successfully produced in high yield (up to 2.5 g/L) penta-N-acetyl-chitop...
Successful metabolic engineering efforts for the generation ofE. colistrains that can overproduce AAA include: (i) increasing the availability of the direct precursors phosphoenolpyruvate (PEP) and erythrose-4-phosphate (E4P); (ii) enhancement of the first enzymatic reaction in the SHK pathway to ...
