Bacillus arsenicoselenatis

Blum J, AB Bindi, J Buzzelli, JF Stolz, RS Oremland (1998) Bacillus arsenicoselenatis sp. nov., and Bacillus selenitrificans sp. nov. two haloalkaliphiles from Mono Lake, California that respire oxyanions of selnium and dixstmc. Arch Microbiol 171 19-30. 

Blum et al. (1998) isolated a bacterial strain Bacillus arsenicoselenatis from muds of Mono Lake, ahypersaline alkaline lake in northern California (see Section 24.2). Under anaerobic conditions in saline water, over an optimum pH range of 8.5-10, the strain can respire using As(V), or arsenate, as the electron acceptor, reducing it to As(III), arsenite. 

Fig. 33.1. Results of a batch experiment (symbols) by Blum et al. (1998) in which Bacillus arsenicoselenatis grows on lactate, using arsenate [As(V)] as an electron acceptor. Solid lines show results of integrating a kinetic rate model describing microbial respiration and growth.

Herbel et al. (2000) reduced Se(VI) to Se(TV) with growing, anaerobic batch cultures of a haloalkaliphile. Bacillus arsenicoselenatis strain EIH, and a batch cultures of a haloalkaliphile. Bacillus arsenicoselenatis strain EIH, and a freshwater bacterium.
