Abstract
Selenium reducing microorganisms produce elemental selenium nanoparticles with particular physico-chemical properties being due to an associated organic fraction. This study identified high affinity proteins being associated with such bionanominerals and with non-biogenic elemental selenium. Proteins with an anticipated functional role in selenium reduction, such as a metalloid reductase, were found associated with nanoparticles formed by one selenium respirer, Sulfurospirillum barnesii.
