Thermodynamic data indicate that the oxidation of oxygenated organic species originating from biomass instead water at anode an electrolysis cell should allow decreasing voltage below 1.23 V. Biosourced alcohols, polyols, sugars, lignocellulosic compounds, and their derivatives are then electroreformed to produce clean hydrogen cathode compounds cells. The reported studies highlight main challe...
Backgrounds and Objectives: A great part of organic compounds cause more pollution in natural waters meet, are chemical dye material. Azo dyes have more usage in different industries. Azo dyes not only give undesirable dye to the water but also have mutation potential and carcinogenesis effects in human and cause the production of toxic substances in water environments.The purpose of this stud...
Hydrogen, the most abundant and lightest element in the universe, has much potential as a future energy source. Hydrogenases catalyse one of the simplest chemical reactions, 2H(+) + 2e(-) ↔ H(2), yet their structure is very complex. Biologically, hydrogen can be produced via photosynthetic or fermentative routes. This review provides an overview of microbial production of hydrogen by fermentati...
BACKGROUND Fermentative hydrogen production is an attractive means for the sustainable production of this future energy carrier but is hampered by low yields. One possible solution is to create, using metabolic engineering, strains which can bypass the normal metabolic limits to substrate conversion to hydrogen. Escherichia coli can degrade a variety of sugars to hydrogen but can only convert e...
