Description générale

Escherichia coli (E.coli) is a non-spore forming, Gram-negative, rod-shaped facultative anerobe, which is found in the human gastrointestinal tract. It belongs to the family of Enterobacteriaceae. E.coli is chemoorganotrophic and grows at 37°C. Pathogenic E.coli strains is associated with diarrhea, septicemia, meningitis and urinary tract infections. It inhibits the colonization of the gut by harmful bacteria. E.coli acts as an indicator of fecal contamination.

Autres remarques

A mutant which is rich in alkaline phosphatase.

We report the development of a dual-enzyme electrochemical biosensor based on microfabricated gold band array electrodes which were first modified by gold foam (Au-foam) in order to dramatically increase the active surface area. The resulting nanostructured Au-foam deposits then served

We have analyzed protein expression and enzyme activity of the sarcoplasmic reticulum Ca2+-transporting ATPase (SERCA) in horse gluteal muscle. Horses exhibit a high incidence of recurrent exertional rhabdomyolysis, with myosolic Ca2+ proposed, but yet to be established, as the underlying
