Cocktail reception: Biohydrogen is produced in high yield from cellulosic materials and water in a one-pot process catalyzed by up to 14 enzymes and one coenzyme. This assembly of enzymes results in non-natural catabolic pathways. These spontaneous reactions are conducted under modest reaction conditions (32 degrees C and atmospheric pressure).

Recently, issues concerning the sustainable and harmless disposal of organic solid waste have generated interest in microbial biotechnologies aimed at converting waste materials into bioenergy and biomaterials, thus contributing to a reduction in economic dependence on fossil fuels. To valorize biomass, waste materials derived from agriculture, food processing factories, and municipal organic w...

Abstract Biohydrogen production in agricultural enterprises is an urgent matter. It appropriate to utilize two methods of biohydrogen production: a thermochemical method – from crop-based biomass and anaerobic digestion (fermentation) animal-based biomass.. use gasifiers for the biore-actors fermentation method. The theoretical potential was established with due regard amount which necessary ut...

Biomethanol is a significant chemical in biochemicals and biofuels. Molasses interested producing biogas biohydrogen for biomethanol. Biohydrogen, Enterobacter aerogenes digested molasses obtaining value organic chemicals appropriate ratios of H2/CO2 then transforming to H2/CO by RWGS. Biogas was converted syngas methanol synthesis. The pathway 4 steps it sailing single product as 3 obtained in...

Photoinduced biohydrogen production systems, coupling saccharaides biomass such as sucrose, maltose, cellobiose, cellulose, or saccharides mixture hydrolysis by enzymes and glucose dehydrogenase (GDH), and hydrogen production with platinum colloid as a catalyst using the visible light-induced photosensitization of Mg chlorophyll-a (Mg Chl-a) from higher green plant or artificial chlorophyll ana...

Sustainable production and utilization of biofuels has an enormous potential for the world’s energy supply. Most research studies usually focus on individual conversion processes and specific end-products. To gain full benefits however, it is important to investigate production and utilization cycles in an integrated way and to consider all important aspects involved: e.g. crop production, resi...

Low-temperature bacteria have potential to produce biohydrogen and are often considered a renewable energy generator for the future. However, presented poor hydrogen yield due slow metabolic rate prolonged lag phase caused by their restricted growth temperature limit. The ineffective search new biocatalysts from cold environments application of modification techniques almost jeopardize economic...
