Isolating Escherichia coli strains for recombinant protein production

Hydrogen production by recombinant Escherichia coli strains

The production of hydrogen via microbial biotechnology is an active field of research. Given its ease of manipulation, the best-studied bacterium Escherichia coli has become a workhorse for enhanced hydrogen production through metabolic engineering, heterologous gene expression, adaptive evolution, and protein engineering. Herein, the utility of E. coli strains to produce hydrogen, via native h...

Advances and challenges in recombinant protein expression in Escherichia coli

Production of specific IgY antibody to the recombinant FanC protein produced in Escherichia coli

Objective(s): Enterotoxigenic Escherichia coli (ETEC) strains are one of the primary causes of diarrhea in newborn calves and in humans, pigs, and sheep. IgY technology has been identified as a promising alternative to generating a mass amount of specific antibody for use in immunotherapy and immunodiagnostics. The purpose of this study was to produce specific antibody by egg yolk antibody (IgY...

Strategies for the production of recombinant protein in Escherichia coli.

In the recent past years, a large number of proteins have been expressed in Escherichia coli with high productivity due to rapid development of genetic engineering technologies. There are many hosts used for the production of recombinant protein but the preferred choice is E. coli due to its easier culture, short life cycle, well-known genetics, and easy genetic manipulation. We often face a pr...

Elevated Fis expression enhances recombinant protein production in Escherichia coli.

A genetic strategy to enhance recombinant protein production is discussed. A small DNA bending protein, Fis, which has been shown to activate rRNA synthesis upon a nutrient upshift, was overexpressed in E. coli strain W3110 carrying vector pUCR1. Overexpression of Fis during exponential growth was shown to activate rrn promoters to different extents. A 5-fold improvement in chloramphenicol acet...
