Abstract

XANES spectroscopy has been used to demonstrate that both the common soil bacterium Bacillus subtilis and an unidentified bacillus isolated from selenium-contaminated soil reduce selenite to the red allotrope of elemental selenium. The red and gray forms of selenium are distinguished by their XANES spectra, although EXAFS spectroscopy shows a single absorber-backscatterer distance in both cases.
