Living sensor can warn of arsenic pollution

EurekAlert! - Chemistry, Physics and Materials Sciences  Sat, 09/06/2008 - 23:00

(Society for General Microbiology) Scientists studying arsenic pollution have discovered a living sensor that can spot contamination.

They have also discovered new bacteria that can clean up arsenic spills even in previously untreatable cold areas, microbiologists heard today (Monday Sept. 8, 2008) at the Society for General Microbiology's Autumn meeting being held this week at Trinity College, Dublin.


 

Energy-saving bacteria resist antibiotics

EurekAlert! - Chemistry, Physics and Materials Sciences  Mon, 09/01/2008 - 23:00

(Society for General Microbiology) Bacteria save energy by producing proteins that moonlight, having different roles at different times, which may also protect the microbes from being killed.

The moonlighting activity of one enzyme from the tuberculosis bacterium makes it partially resistant to a family of broad-spectrum antibiotics, according to a paper published in the September issue of the journal Microbiology.

(Society for General Microbiology) Big pharma gave up on soil bacteria as a source of antibiotics too soon, according to research published in the June issue of Microbiology.

Scientists have been mining microbial genomes for new natural products that may have applications in the treatment of MRSA and cancer and have made some exciting discoveries.


 

Scientists discover why plague is so lethal

EurekAlert! - Chemistry, Physics and Materials Sciences  Sat, 05/03/2008 - 23:00

(Society for General Microbiology) Bacteria that cause the bubonic plague may be more virulent than their close relatives because of a single genetic mutation, according to research published in the May issue of the journal Microbiology.
