General description

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.

Other Notes

A mutant which is rich in alkaline phosphatase.

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

Design and development of scale-down approaches, such as microbioreactor (μBR) technologies with integrated sensors, are an adequate solution for rapid, high-throughput and cost-effective screening of valuable reactions and/or production strains, with considerably reduced use of reagents and generation of waste.

We develop a low-background electrochemical biosensor for one-step detection of uracil DNA glycosylase (UDG) based on the host-guest interaction and iron-embedded nitrogen-rich carbon nanotube (Fe-N-C) that mimics enzyme-mediated electrocatalysis to achieve signal amplification. In this work, Fe-N-C is initially immobilized

Owing to their high surface area, stability, and functional groups on the surface, iron oxide hydroxide nanoparticles have attracted attention as enzymatic support. In this work, a chemometric approach was performed, aiming at the optimization of the horseradish peroxidase (HRP)
