Abstract
- A novel acidophilic, aerobic bacterium strain, MYW30-H2<superscript>T</superscript>, was isolated from a heap of polymetallic mine. Cells of strain MYW30-H2<superscript>T</superscript> were Gram-stain-positive, endospore-forming, motile, and rod-shaped. Strain MYW30-H2<superscript>T</superscript> 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<superscript>T</superscript> 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<subscript>15:0</subscript> and anteiso-C<subscript>15:0</subscript> were the major cellular fatty acids. The 16S rRNA gene sequence analysis showed that MYW30-H2<superscript>T</superscript> was phylogenetically affiliated with the family Alicyclobacillaceae, and the sequence similarity with other Alicyclobacillaceae genera species was below 91.51%. The average amino acid identity value of the strain with its phylogenetically related species was 52.3–62.1%, which fell into the genus boundary range. The DNA G+C content of the strain was 44.2%. Based on physiological and phylogenetic analyses, strain MYW30-H2<superscript>T</superscript> represents a novel species of a new genus of the family Alicyclobacillaceae, for which the name Fodinisporobacter ferrooxydans gen. nov., sp. nov. is proposed. The type strain is MYW30-H2<superscript>T</superscript> (=CGMCC 1.17422<superscript>T</superscript> = KCTC 43278<superscript>T</superscript>). [ABSTRACT FROM AUTHOR]
