چکیده

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).

In vitro metabolic engineering of hydrogen production at theoretical yield from sucrose.

Hydrogen is one of the most important industrial chemicals and will be arguably the best fuel in the future. Hydrogen production from less costly renewable sugars can provide affordable hydrogen, decrease reliance on fossil fuels, and achieve nearly zero net greenhouse gas emissions, but current chemical and biological means suffer from low hydrogen yields and/or severe reaction conditions. An ...

Production of Hydrogen and Synthesis gas via Cu-Ni/Al2O3 catalyzed gasification of bagasse in supercritical water media

Bagasse as a real biomass was converted to hydrogen rich gas via catalytic supercritical water gasification process. To find the effect of Cu on selectivity of products, Cu promoted Ni-γAl2O3 catalysts were prepared with 1 to 20wt% Ni and 0.5 to 10wt% Cu loadings via impregnation method. Catalysts were characterized by ICP, BET, XRD, H2 chemisorption and TEM technique as well CHNS analysis was ...

Key Pretreatment Technologies on Cellulosic Ethanol Production

Conversion of lignocellulosic biomass to fuel ethanol involves pretreatments followed by enzyme-catalyzed hydrolysis to generate fermentable sugars. Efficient pretreatment method can significantly enhance hydrolysis of biomass and thus reduce ethanol production cost. Cellulosic plant materials are mainly composed of cellulose, hemicellulose and lignin, the cheapest source of fermentable sugars....

Purification and biochemical properties of a thermostable, haloalkaline cellulase from Bacillus licheniformis AMF-07 and its application for hydrolysis of different cellulosic substrates to bioethanol production

A thermophilic strain AMF-07, hydrolyzing carboxymethylcellulose (CMC) was isolated from Kerman hot spring and was identified as Bacillus licheniformis based on 16S rRNA sequence homology. The carboxymethylcellulase (CMCase) enzyme produced by the B. licheniformis was purified by (NH4)2SO4 precipitation, ion exchange and gel filtration chromatography. The purified enzyme gave a single band on S...

Simultaneous saccharification and cofermentation of lignocellulosic residues from commercial furfural production and corn kernels using different nutrient media

BACKGROUND As the supply of starch grain and sugar cane, currently the main feedstocks for bioethanol production, become limited, lignocelluloses will be sought as alternative materials for bioethanol production. Production of cellulosic ethanol is still cost-inefficient because of the low final ethanol concentration and the addition of nutrients. We report the use of simultaneous saccharificat...
