A year ago, biofuel was a buzzword, a reasonable technical solution to many of our environmental problems. Politicians across the European Union and in North America were busy setting targets, deciding what percentage of transport fuels should be replaced by biofuels by what time. The corn-ethanol industry in the US went into overdrive, and many governments in the developing world set up fuel c...

Uncovering genetic control of variation in ethanol tolerance in natural populations of yeast Saccharomyces cerevisiae is essential for understanding the evolution of fermentation, the dominant lifestyle of the species, and for improving efficiency of selection for strains with high ethanol tolerance, a character of great economic value for the brewing and biofuel industries. To date, as many as...

This is an overview of the emerging technologies that have been developed recently or are in the process of development for ethanol (biofuel) production from agricultural residues. )n this direction numerous advances have been made. Problems associated with inhibitor generation and detoxification, fermentation of both hexoses and pentoses to ethanol, and development of efficient microbial strai...

Biofuel production processes at high gravity are currently under development. Most of these processes however use sugars or first generation feedstocks as substrate. This paper presents the results of a life cycle assessment (LCA) of the production of bio-ethanol at high gravity conditions from a second generation feedstock, namely, wheat straw. The LCA used lab results of a set of 36 process c...

Ethanol is a biofuel produced from renewable resources, which potentially plays an important role in solving future fuel problems. This study aimed to select the highest ethanol-producing isolate candidates obtained previously isolated ragi and cassava tapai. The selection process was conducted 2 stages, namely: 1) Selection of seven using PYG media containing peptone, yeast extract, glucose at...

Total biofuel demand in areas like transport and energy is set to grow by almost 30% annually reach 50 billion gallons 2026. Biofuels' association with sustainable development has been a subject of discussion among researchers policymakers. Even the most robust studies on this topic examine only small number indicators across limited countries. This study analyzes whether production could advan...

Recently the support of biofuel production has been a politically sensitive topic. Politicians have pushed for support for fuel ethanol production as an environmentally friendly alternative to imported oil, as well as a way to boost farm profits and improve rural livelihoods. Several government policies actively promote ethanol production via tax incentives and mandates, and these policies are ...
