Abstract
Pyrite is a key mineral in the global biogeochemical cyclesof sulfur and iron, yet its anaerobic microbial oxidation has eludedgeochemists and microbiologists for decades. Recent reports indicated thatanaerobic oxidation of pyrite is occurring, but the mechanism remainsunclear. Here, we provide evidence for the capability of Thiobacillusdenitrif icans to anaerobically oxidize a putatively nanosized pyrite particlefraction with nitrate as electron acceptor. Nanosized pyrite was readilyoxidized to ferric iron and sulfate with a rate of 10.1 μM h−1. The massbalance of pyrite oxidation and nitrate reduction revealed a closedrecovery of the electrons. This substantiates a further “missinglithotrophy” in the global cycles of sulfur and iron and emphasizes thehigh reactivity of nanominerals in the environment.
