A new genus of beta-Proteobacteria has been isolated from bioreactors treating oxalate wastes that are produced by Bayer refining of bauxite into alumina. The bacteria are indigenous to the alumina refinery environment and are capable of removing up to 40 tonnes of oxalate wastes produced on sit... Read More

When I first saw this photomicrograph of Haemophilus influenzae via immunofluorescence, I thought of the opening days of the first Gulf War, when CNN showed wall to wall images of the bombing of Baghdad.

Virus-bacterium associations were examined in the natural environment of a termite's hindgut. Three general scenarios were seen. In the first (1) there was a one-to-one association: one type of virus matched one type of bacterium host. In the second (2) the host bacterium was associated wi... Read More
