Biofuel costs, benefits are focus of public forum, Nov. 14

The profitability of corn ethanol processing, the costs and benefits of ethanol as a fuel source, the impact of the ethanol boom on rural America and the future of the biofuel industry will be among topics explored at a free public forum on the economics of ethanol to be held on campus from 8:30 a.m. to 4:30 p.m. Nov. 14.

New technique makes corn ethanol process more efficient

Researchers at Washington University in St. Louis are proposing to borrow a process used in breweries and wastewater treatment facilities to make corn ethanol more energy efficient. They are exploring the use of oxygen-less vats of microorganisms that naturally feed on organic waste produced from the ethanol fermentation process.

New techniques create butanol

Business school students work out plan for biofuels in undeveloped countries

Henning and D1 Oils; www.jatropha.orgJatropha plantsDuring a practicum for the World Agricultural Forum, Washington University M.B.A. students realized that using ethanol as an alternative fuel in developing countries isn’t cost effective. Instead, they stumbled upon the jatropha plant, a hardy shrub with seeds that can easily produce oil to power basic generators. The students’ work demonstrated the potential for economic stability that jatropha could offer small villages. More…

Biologist finds cell wall construction pathway

Photo courtesy USDAA WUSTL biologist has advanced the understanding of plant cell walls, which are crucial to plants such as cotton, which needs the cell wall to impart elasticity in cotton fibers.Wood with altered properties and cheaper ethanol through more efficient production are two possibilities as a result of a find by a biologist at Washington University in St. Louis. Erik Nielsen, Ph.D., Washington University biologist , has made a discovery published in a recent edition of The Journal of Cell Biology that sheds new light on how some types of complex sugars in plants are directed to the construction of cell walls.

Department of Energy Funds cyanobacteria sequencing project

That’s a lot of power potential from microscopic cyanobacteria (blue-green algae) that capture sunlight and then do a variety of biochemical processes. One potential process, the clean production of ethanol, is a high priority for DOE. Himadri Pakrasi, Ph.D., Washington University Professor of Biology in Arts & Sciences, and Professor of Energy in the School of Engineering and Applied Science, will head a team of biologists at Washington University and elsewhere in the analysis of the genomes of six related strains of Cyanothece bacteria.

Sensitivity to alcohol affected by genes active in neurons

In these brain sections of neonatal mice exposed to ethanol, mice deficient in certain enzymes (right) exhibit much more neurodegeneration as indicated by the black material in the dying neurons.Can you blame your genes if you can’t handle your liquor? A new study conducted at the School of Medicine may pave the way to finding out. Researchers found that the brain’s response to alcohol is partially under the influence of two genes. The genes, studied in both adult and newborn mice, were found to affect sensitivity to alcohol intoxication, interest in alcohol consumption and risk of developmental brain damage from alcohol.
