New research suggests that infection with a probiotic strain of E. coli bacteria could help treat an reduce the negative effects of another E. coli infection that may be associated with Crohn's disease. Researchrs from the University of Auckland, New Zealand publish their results in the April 2011 issue of the journal Applied and Environmental Microbiology. Crohn's disease is a common chronic disorder that affects the gastrointestinal tract and is believed to develop as a result of an...

Altering microbe's metabolism leads to big jump in n-butanol production Researchers at UCLA's Henry Samueli School of Engineering and Applied Science have developed a way to produce normal butanol "” often proposed as a "greener" fuel alternative to diesel and gasoline "” from bacteria at rates significantly higher than those achieved using current production methods. The findings, reported online in the journal Applied and Environmental Microbiology, mark an important advance in...

In the quest for inexpensive biofuels, cellulose proved no match for a bioprocessing strategy and genetically engineered microbe developed by researchers at the Department of Energy's BioEnergy Science Center. Using consolidated bioprocessing, a team led by James Liao of the University of California at Los Angeles for the first time produced isobutanol directly from cellulose. The team's work, published online in Applied and Environmental Microbiology, represents across-the-board savings in...

Infants are more efficient at digesting and utilizing nutritional components of milk than adults due to a difference in the strains of bacteria that dominate their digestive tracts. Researchers from the University of California, Davis, and Utah State University report on genomic analysis of these strains in the November 2010 issue of the journal Applied and Environmental Microbiology identifying the genes that are most likely responsible for this difference. "Human milk oligosaccharides...

Some trees growing in nutrient-poor forest soil may get what they need by cultivating specific root microbes to create compounds they require. These microbes are exceptionally efficient at turning inorganic minerals into nutrients that the trees can use. Researchers from France report their findings in the July 2010 issue of the journal Applied and Environmental Microbiology. "In acidic forest soils, availability of inorganic nutrients is a tree-growth-limiting factor. A hypothesis to explain...

A research team at the DOE Great Lakes Bioenergy Research Center (GLBRC) has developed a powerful new tool that promises to unlock the secrets of biomass degradation, a critical step in the development of cost-effective cellulosic biofuels. The details of this method were published online on June 11 in the journal Applied and Environmental Microbiology. Fulfilling the promise of cellulosic biofuels requires developing efficient strategies to extract sugar molecules in biomass polymers like...

When the forces of evolution took over an experimental strain of bacteria, it derailed an experiment Duke and NC State researchers thought they were conducting, but led to something much more profound instead. The researchers used a colony of mice raised in a large plastic bubble, called an isolator, that was completely sterile, lacking even a single bacterium. They introduced a single type of bacteria into the mouse colony, but it mutated quickly into different types, making new bacteria...

Bacteria common to spacecraft may be able to survive the harsh environs of Mars long enough to inadvertently contaminate Mars with terrestrial life according to research published in the April 2010 issue of the journal Applied and Environmental Microbiology. The search for life on Mars remains a stated goal of NASA's Mars Exploration Program and Astrobiology Institutes. To preserve the pristine environments, the bioloads on spacecraft headed to Mars are subject to sterilization designed to...

Researchers from the University of Georgia College of Veterinary Medicine have made an "unexpected" dual discovery that could open new avenues for treating Ichthyophthirius multifiliis, or "Ich", a devastating single-celled protozoan parasite that commonly attacks freshwater fish. With the aid of whole-genome sequencing, researchers found that Ich harbors two apparently symbiotic intracellular bacteria: Bacteroides, which are usually found free-living, and Rickettsia, which are obligate...

With the introduction of a single bacterial gene into yeast, researchers from Delft University of Technology in the Netherlands achieved three improvements in bioethanol production from agricultural waste material: 'More ethanol, less acetate and elimination of the major by-product glycerol' This week the invention was published in the scientific journal Applied and Environmental Microbiology. Car fuel Bioethanol is made by the yeast Saccharomyces cerevisiae from sugars obtained from plant...
