Escherichia coli and its application to biohydrogen production
"Hydrogen is an attractive energy carrier because of its high energy density, and used as a raw material in various chemical processes. Nowadays, hydrogen demand is supplied from non-renewable sources, and alternative sources are becoming mandatory. Hydrogen production by biological methods use...

| Sumario: | "Hydrogen is an attractive energy carrier because of its high energy density, and used as a raw material in various chemical processes. Nowadays, hydrogen demand is supplied from non-renewable sources, and alternative sources are becoming mandatory. Hydrogen production by biological methods uses renewable resources as substrate and its production occurs at ambient temperature and atmospheric pressure. Thus, it is less energy intensive than the chemical and thermochemical methods used to produce hydrogen. This review is focused on fermentative hydrogen production by Escherichia coli. The hydrogen production pathway, the genetic manipulations, and expression of non-native pathways into this microorganism are reviewed. The hydrogen production using alternative substrates is a critical point to develop sustainable process by this reason the principal substrates for hydrogen production using E. coli are revised. Other strategies like two stages processes and immobilized cells are also discussed." |
