GEN reports on alternative feedstocks for ethanol production
June 22, 2009Scientists say they are forging ahead in developing replacements for petrochemical fuels that will be cost-competitive and renewable while having a minimal impact on the environment, reports Genetic Engineering & Biotechnology News (GEN). A consensus is emerging that no one technology will reign supreme and that a range of current and novel methodologies will contribute to meeting biofuel needs, according to the June 15 issue of GEN (http://www.genengnews.com/articles/chitem.aspx?aid=2942).
"It's been estimated that fossil fuels constitute more than eighty percent of the world's main energy supply," says John Sterling, Editor in Chief of GEN. "Both economics and the concern over global warming require that technologies be used to significantly lower this number."
Edenspace Systems is working on Energy Corn™, a feedstock designed to cut the cost of producing cellulosic biofuels from corn stover. The company's technology platform, based on identifying promising cellulose genes, transforming crop plants with candidate genes, and evaluating the effects on growth, yield, and cellulose hydrolysis, would be applicable to a variety of energy crops including switchgrass, sorghum, and sugar cane.
Officials at Coskata say the company relies on a hybrid approach based on its Flex Ethanol™ technology, which combines gasification and fermentation in a thermo-biological pathway to produce fuel-grade ethanol that it contends can be cost-competitive with gasoline. The process reportedly is able to yield more than 100 gallons of ethanol per ton of dry biomass.
Also discussed in the GEN article is biofuel research taking place at ICM, Qteros, Synthetic Genomics, Solazyme, and the United States Department of Agriculture.

Ethanol Production Current Events and Ethanol Production News RSSWet ethanol production process yields more ethanol and more co-products
Using a wet ethanol production method that begins by soaking corn kernels rather than grinding them, results in more gallons of ethanol and more usable co-products, giving ethanol producers a bigger bang for their buck - by about 20 percent.
UC Riverside Researchers Create First Synthetic Cellulosome in Yeast
A team of researchers led by University of California, Riverside (UCR) Professor of Chemical Engineering Wilfred Chen has constructed for the first time a synthetic cellulosome in yeast, which is much more ethanol-tolerant than the bacteria in which these structures are normally found.
Standards for a new genomic era
A team of geneticists at Los Alamos National Laboratory, together with a consortium of international researchers, has recently proposed a set of standards designed to elucidate the quality of publicly available genetic sequencing information.
Reject watermelons -- the newest renewable energy source
Watermelon juice can be a valuable source of biofuel. Researchers writing in BioMed Central's open access journal Biotechnology for Biofuels have shown that the juice of reject watermelons can be efficiently fermented into ethanol.
Study finds migratory birds not picky about their rest stops
If a lush, protected forest with a winding stream is considered luxury accommodation for a migratory bird, a Purdue University study shows that those birds would be just as happy with the equivalent of a cheap roadside motel.
Bioethanol's impact on water supply 3 times higher than once thought
At a time when water supplies are scarce in many areas of the United States, scientists in Minnesota are reporting that production of bioethanol - often regarded as the clean-burning energy source of the future - may consume up to three times more water than previously thought.
New method uses electrolyzed water for more efficient fuel production
Using electrolyzed water rather than harsh chemicals could be a more effective and environmentally friendly method in the pretreatment of ethanol waste products to produce an acetone-butanol-ethanol fuel mix, according to research conducted at the University of Illinois.
Ethanol Production Could Jeopardize Soil Productivity
There is growing interest in using crop residues as the feedstock of choice for the production of cellulosic-based ethanol because of the more favorable energy output relative to grain-based ethanol.
Midwestern ethanol plants use much less water than western plants, U of Minnesota study says
Ethanol production in Minnesota and Iowa uses far less water overall than similar processes in states where water is less plentiful, a new University of Minnesota study shows.
Tiny Super-Plant Can Clean Up Hog Farms and Be Used For Ethanol Production
Researchers at North Carolina State University have found that a tiny aquatic plant can be used to clean up animal waste at industrial hog farms and potentially be part of the answer for the global energy crisis.

Alcohol Can Be a Gas!: Fueling an Ethanol Revolution for the 21st Century by David Blume (Author), Michael Winks (Editor), R. Buckminster (FWS) Fuller (Editor) Alcohol Can Be a Gas! is the only comprehensive book ever written on alcohol fuel production and use for home and farm. Until now, it has been very difficult for farmers, contractors, alternative energy aficionados, those concerned about Peak Oil, and small-scale entrepreneurs to obtain good, accurate information on producing alcohol, or on converting vehicles to run on alcohol fuel. And with all the conflicting news stories about ethanol, the public finds it difficult to sort fact from fiction. This text, which has been reviewed by scientists around the world, is the definitive reference work on alcohol fuel. Alcohol Can Be A Gas! contains 640 8-1/2 by 11 pages, with 514 charts, photos, and illustrations to reinforce the information-dense text. The book is geared for the... |

![Use of post-harvest sugarcane residue for ethanol production [An article from: Bioresource Technology]](http://ecx.images-amazon.com/images/I/512SA5QAAFL._SL160_.jpg) |
Use of post-harvest sugarcane residue for ethanol production [An article from: Bioresource Technology] by L. Dawson (Author), R. Boopathy (Author) This digital document is a journal article from Bioresource Technology, published by Elsevier in 2007. The article is delivered in HTML format and is available in your Amazon.com Media Library immediately after purchase. You can view it with any web browser. Description: Agricultural residues are produced in large quantities throughout the world. Approximately, 1kg of residue is produced for each kilogram of grains harvested. This ratio of grain/residue translates into an excess of 40 billion ton of crop residue produced each year in the USA. These residues are renewable resources that could be used to produce ethanol and many other value added products. In this study, we demonstrate that the post-harvest sugar cane residue could be used to produce fuel grade ethanol. A... |
