Diverse <i>Sulfuriferula</i> spp. from sulfide mineral weathering environments oxidize ferrous iron and reduced inorganic sulfur compounds.

ABSTRACT: Microorganisms are important catalysts for the oxidation of reduced inorganic sulfur compounds. One environmentally important source of reduced sulfur is metal sulfide minerals that occur in economic mineral deposits and mine waste. Previous research found that Sulfuriferula spp. were abundant and active in long-term weathering experiments with simulated waste rock and tailings from the Duluth Complex, Northern Minnesota. We, therefore, isolated several strains of Sulfuriferula spp. from these long-term experiments and characterized their metabolic and genomic properties to provide insight into microbe-mineral interactions and the microbial biogeochemistry in these and other moderately acidic to circumneutral environments. The Sulfuriferula strains are all obligate che
