A farm-scale process for converting wheat straw to ethanol was modelled to assess its energy performance. The process … incorporates the on-site production of crude unprocessed liquid cellulase produced via solid-state fermentation, and the anaerobic …–90 % in the energy required to produce and transport the cellulase compared to commercial preparations, and a net surplus of …

This study investigates ethanol production from simultaneous fermentation and saccharification (SFS) and separated … products: rice byproduct (composed of AFEX-treated rice rust and rice bran), whey and sugarcane bagasse. The ethanol was …/wt) and CaCl2 (2.0% wt/wt). The best result for ethanol fermentation (11.7 g/L of ethanol) was obtained after 12 h of SFS at …

Ethanol production from cellulosic sources such as switchgrass (Panicum virgatum L.) requires the use of natural … amount of environmental, fossil fuel, and human-derived energy required to produce ethanol from switchgrass. Emergy is the … directly or embodied in purchased goods, and 25% came from human-derived services indirectly. Ethanol production per petroleum …

cellulose (Avicel® PH-101) to ethanol. In the first step, cellulose was selectively converted to glucose. Cellulose hydrolysis …, irradiation time, and power consumption – were optimized. A yield of 0.67 g glucose/g cellulose was achieved under modest reaction … converted to ethanol by fermention with yeast (Saccharomyces cerevisiae). The speed, selective nature of the process and the …

A newly isolated soil fungus, Penicillium sp. TG2, had cellulase activities that were comparable to those of … Trichoderma reesei RUT-C30, a common commercial strain used for cellulase production. The maximal and specific activities were 1 …-glucosidase, and 0.45 U/mL and 0.81 U/mg for filter paper cellulase (FPase), respectively. Optimal FPase activity was at pH 5.0 and 50 …

the development of 2G biofuels? We find that ethanol made from cellulose using the biochemical conversion process is far … ethanol might induce a switch from 1G to 2G biofuels. However, we find little evidence that production and use of 1G biofuels …

Cellulose reactivity in ethanol at elevated temperature (170–210 °C) was investigated in this study. Water and acid … catalyst can improve the solubilization and the conversion of cellulose in ethanol. In ethanol/water medium, more humic solids … will be formed, but the amounts of diethyl ether decreased greatly. In ethanol medium, the ethanolysis reaction of …

-glucosidase activity was observed. This study shows that cellulase secretion in S. cerevisiae could be greatly improved with strain …

A major constraint in the enzymatic saccharification of biomass for ethanol production is the cost of cellulase enzymes … on wheat bran as substrate. Crude cellulase and a relatively glucose tolerant BGL were produced using fungi Trichoderma … cellulase and 10U of β-glucosidase per gram of pretreated biomass. Highest yield of reducing sugars (26.3g/L) was obtained from …
