Microbes at work cleaning up the environment

...aggregation in sulfate-reducing bacteria dominated biofilms collected from the Piquette Mine, a flooded system in southwestern Wisconsin. The team found that organic nitrogen was highly concentrated in all of the zinc-sulfide aggregates, indicating a high protein or polypeptide content relative to inorgani...

Search on for treatment of slow-healing wounds

...hase equipment for its investigation into the role biofilms play in chronic wounds. The money will be distribu...eating up to 100 patients daily, Wolcott suspected biofilms might play a role in his patients' persistent wounds. Tissue samples analyzed by the CBE from Wol...

Research highlights how bacteria produce energy

...ng the bacteria in microbial fuel cells to grow on biofilms on the electrodes of a fuel cell. This week, Gemm...acteria are able to transfer electrons through the biofilms to the electrodes. "Cells at a distance from the anode remained viable with no decrease in the effi...

First human trial of antibacterial contact lens

.... The US Centers for Disease Control estimate that biofilms account for at least two-thirds of all chronic bacterial infections. Biosignal and the Institute for Eye Research have tested antibiofilm compounds and generated proof of concept data in a broad range of product categories in the medical, industri...

Anthrax spores may survive water treatment

...pes, 95 percent attached to the iron pipes. When biofilms were present on the interior of copper pipes attac...n tolerate water treatment, can attach to pipes or biofilms within the pipes, and could pass through pipe systems to reach the consumer tap," says Calomiris. ...

Proteomics brings researchers closer to understanding microbes that produce acid mine drainage

...es of the Richmond Mine biofilm and acid producing biofilms elsewhere, which includes work with the Joint Genome Institute to obtain more genomes of community members. "We really want to know how the environment drives the community, how the environment selects for the membership of the community, and then w...

Understanding how bacteria communicate may help scientists prevent disease

...ant to antibiotics, so preventing the formation of biofilms or short-circuiting bacteria's ability to become virulent by disturbing their communication network so they remain harmless, is an alternative strategy to controlling disease," he said. Kulkarni will continue his collaboration with the Princeton Uni...

To control germs, scientists deploy tiny agents provocateurs

...hulls. If a single cell were analogous to one man, biofilms would be the "bacterial equivalent of mob mentality," says Blackwell. In the realm of health, biofilms are at the root of growing numbers of tenacious, and sometimes fatal, hospital infections, says Blac...

Robot-based system developed at Carnegie Mellon detects life in Chile's Atacama desert

...anisms and visualizing high levels incorporated as biofilms or colonies," said Gregory Fisher, project imaging scientist. "Our fluorescent imager is the first such system to work in the daylight while in the shade of the rover. The rover uses solar energy to operate so it needs to travel during daylight hour...

Substance protects resilient staph bacteria

...Dr. Otto's research of how Staphylococcal bacteria biofilms contribute to evading human immune defenses. Biofilms are protective cell-surface structures. Biofilm formation does not depend on PGA, but other research in Dr. Otto's laboratory has indicated that PGA production is greater when a biofilm is present...
