.... The understanding of the influence of Fe-oxidizing bacteria in mineral exploration has been limited to acidic, near surface environments, where oxygen is in abundance and acidophilic organisms can exist. However, microorganisms capable of Fe-oxidation at neutral pH and anoxic (or near-anoxic) conditions have been...

The data presented here reveal that these filaments represent remains of colorless, vacuolated sulfide-oxidizing bacteria. This interpretation...

... and Felder, 1987 ; Fallick et al. , 2001 ). Lead is, nevertheless, a toxic metal that is capable of inhibiting sulphate-reducing activity (e.g. Capone et al. , 1983 ; Loka Bharathi et al. , 1990 ). The existence of Pb in BSR pyrite suggests that bacteria were tolerant to Pb in diagenetic fluids. Lead...
