Alkali-loving extremophile bacteria. Coloured scanning electron micrograph of Bacillus selenitireducens (bright orange rods) with crystals of tellurium (upper right). This species of bacteria is haloalkaliphilic (salt and alkali-loving) and was found in the bottom sediment of Mono Lake, USA. It can grow in oxygen deprived conditions with a pH range of It can grow on arsenate, which is water insoluble, reducing it to arsenite which is water soluble and highly toxic. B. selenitireducens may offer benefits to man as it grows nanometre-sized spheres of selenium on the outer membrane that could be used to develop new types of miniature semiconducting devices.
