UT Arlington researchers focusing on the Amazon recently found that widespread conversion from rainforest to pastureland has significant effects on microorganism communities that may lead to a reduction in the region’s role as a reservoir for greenhouse gas. The Amazon rainforest is the largest terrestrial reservoir or “sink” for carbon dioxide, a gas that has been linked to climate change. Through photosynthesis, the Amazon absorbs 1.5 billion tons of carbon dioxide from the...

A benign crystal protein, produced naturally by bacteria and used as an organic pesticide, could be a safe, inexpensive treatment for parasitic worms in humans and provide effective relief to over a billion people around the world. Researchers from the University of California, San Diego, La Jolla, CA, report on this potentially promising solution in a study published ahead of print in the journal Applied and Environmental Microbiology. Hookworms, and other intestinal parasites known as...

According to the Centers for Disease Control, about one in six Americans gets food poisoning each year. Additionally, virus infection risks from consumption of raw oysters in the U.S. are estimated to cost around $200 million a year. To address the issue of health risk from eating raw oysters, Texas A&M University graduate student Chandni Praveen, along with Texas A&M AgriLife Research scientist Dr. Suresh Pillai and a team of researchers from other agencies and institutions,...

The microbial population in the air of the New York City subway system is nearly identical to that of ambient air on the city streets. This research, published ahead of print in the journal Applied and Environmental Microbiology, establishes an important baseline, should it become necessary to monitor the subway's air for dispersal of potentially dangerous microbes. Also, the combination of new methodologies in the study, including fast collection of aerosols and rapid sequencing technology,...

Washington University engineering researchers have created a new type of air-cleaning technology that could better protect human lungs from allergens, airborne viruses and ultrafine particles in the air. The device, known as the SXC ESP, was created by a team led by Pratim Biswas, PhD, the Lucy & Stanley Lopata Professor and chair of the Department of Energy, Environmental & Chemical Engineering in the School of Engineering & Applied Science. A recent study of the device,...

Sourdough bread resists mold, unlike conventionally leavened bread. Now Michael Gaenzle and colleagues of the University of Alberta, Edmonton, show why. During sourdough production, bacteria convert the linoleic acid in bread flour to a compound that has powerful antifungal activity. The research, which could improve the taste of bread, is published online ahead of print in the journal Applied and Environmental Microbiology. The major benefits from the research are twofold: better tasting...

JBEI Researchers Develop a New Candidate for a Cleaner, Greener and Renewable Diesel Fuel A class of chemical compounds best known today for fragrance and flavor may one day provide the clean, green and renewable fuel with which truck and auto drivers fill their tanks. Researchers at the U.S. Department of Energy´s Joint BioEnergy Institute (JBEI) have engineered Escherichia coli (E. coli) bacteria to generate significant quantities of methyl ketone compounds from glucose. In...

With salmonella-tainted ground turkey sickening more than 100 people and listeria-contaminated cantaloupes killing 15 this year, the ability to detect outbreaks of food-borne illness and determine their sources has become a top public health priority. A new approach, reported online Oct. 14 in the journal Applied and Environmental Microbiology by a collaborative team led by Cornell University scientists, will enable government agencies and food companies to pinpoint the exact nature and...

Scientists have tested a predatory bacterium "“ Bdellovibrio "“ against Salmonella in the guts of live chickens. They found that it significantly reduced the numbers of Salmonella bacteria and, importantly, showed that Bdellovibrio are safe when ingested. The research was funded by the Biotechnology and Biological Sciences Research Council, carried out by Professor Liz Sockett's team at The University of Nottingham, with Dr Robert Atterbury and Professor Paul Barrow at the...

Matt Shipman, North Carolina State University Researchers have long known that landfills produce methane, but had a hard time figuring out why "“ since landfills do not start out as a friendly environment for the organisms that produce methane. New research from North Carolina State University shows that one species of microbe is paving the way for other methane producers. Specifically, the researchers found that an anaerobic bacterium called Methanosarcina barkeri appears to be the key...
