WUSTL researchers demonstrate solar-panel-powered microbial electrosynthesis to produce n-butanol from light, CO2 and power

Green Car Congress

Researchers at Washington University in St. Louis have discovered a new way to train microbes to make n -butanol. Here we have harnessed the power of microbes to convert carbon dioxide into value-added multi-carbon compounds in a usable biofuel. We hope that it can be a steppingstone for future sustainable solar fuel production.

Study links PM2.5 pollution to increased risk of diabetes; even low levels pose risk

Green Car Congress

A study by a team from Washington University School of Medicine in St. Louis and the Veterans Affairs (VA) St. Louis Health Care System links PM 2.5 pollution—even at levels deemed safe—to an increased risk of diabetes globally. Our research shows a significant link between air pollution and diabetes globally.

Inorganic mercury converted to more toxic and bio-accumulative monomethylmercury in ocean waters, possibly by microbes

Green Car Congress

Those high levels could also account for a significant amount of the mercury found in Arctic marine organisms. Lehnherr found that the relatively harmless inorganic mercury was converted, through methylation, into the neurotoxin monomethylmercury.

$12+M awarded to 4 projects seeking to design crops with ability to fix their own nitrogen; no artificial fertilizers

Green Car Congress

it needs to be converted into a form that plants can use. While some organisms can fix nitrogen, they have to have special adaptations to limit oxygen. These bacteria are held in root nodules and convert the nitrogen gas found abundantly in the air into nitrogen fertilizer that plants need for growth. Louis biologist Himadri B.

Biofuel cells could power electrical gadgets

Green Cars News

Scientists are developing a way to use nature’s own power stations, mitochondria, to convert organic matter into energy. According to the BBC, scientists at St Louis University in Missouri, US have developed a prototype cell, similar to the ones our own bodies, which can convert almost anything into energy.

New JBEI Methodology Speeds Search for Cellulosic Biofuel Microbes

Green Car Congress

Working with Keasling on this study were Rajat Sapra, a biochemist with Sandia National Laboratories who directs the enzyme optimization program at JBEI, and Yinjie Tang, a chemical engineer now with Washington University in St. Their results were reported in a paper in the 1 April 2009 issue of the journal Biotechnology and Bioengineering.
