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 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

Active fragments (bioactive peptides) from the chicken egg white proteins were expected to exert tyrosinase inhibitory activities in which skin hyperpigmentation could be prevented. Egg white was hydrolyzed by trypsin, chymotrypsin and the combination of both enzymes. The enzyme treatments

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)

The present study describes the kinetics of L-lysine-α-oxidase (LO) from Trichoderma viride immobilised by co-crosslinking onto the surface of a Pt electrode. The resulting amperometric biosensor was able to analyse L-lysine, thus permitting a simple but thorough study of the
