Why is it important?
All inorganic forms of arsenic are highly toxic. In solution, arsenic is available to the biota, but if it is in the solid phase provided by the secondary iron minerals, it is not available to the biota.
Perspectives
This work could inspire the development of systems for biological cleaning of arsenic-polluted water.
