Fodinisporobacter ferrooxydans gen. nov., sp. nov.-A Spore-Forming Ferrous-Oxidizing Bacterium Isolated from a Polymetallic Mine.

ABSTRACT: A novel acidophilic, aerobic bacterium strain, MYW30-H2^T, was isolated from a heap of polymetallic mine. Cells of strain MYW30-H2^T were Gram-stain-positive, endospore-forming, motile, and rod-shaped. Strain MYW30-H2^T grew at a temperature range of 30-45 °C (optimum 40 °C) and a pH range of 3.5-6.0 (optimum 4.0) in the presence of 0-0.5% (w/v) NaCl. Strain MYW30-H2^T could grow heterotrophically on yeast extract and glucose, and grow mixotrophically using ferrous iron as an electron donor with yeast extract. Menaquinone-7 (MK-7) was the sole respiratory quinone of the strain. Iso-C_15:0 and anteiso-C_15:0 were the major cellular fatty acids. The 16S rRNA gene sequence analysis showed that MYW30-H2^T was p
