The cells were motile rods (1–5×0.5–0.6 μm) that stained Gram-negative and possessed polar flagella. Strain Red1T obtained energy from the reduction of Fe(III), Mn(IV), nitrate, elemental sulfur and trimethylamine N-oxide in the presence of a wide range of electron donors, including a variety of organic acids, alcohols, biological extracts and hydrogen. Strain Red1T was incapable of fermentative growth. The novel isolate grew optimally at 40 °C (temperature range for growth, 30–50 °C) and at pH 7 (pH range, 6–9) with 2 % (w/v) NaCl (NaCl range, 0.1–10 %, w/v). The DNA G+C content was 52.5 mol%. Phylogenetic analysis of the 16S rRNA gene sequence indicated that strain Red1T was a member of the order Desulfuromonadales within the class Deltaproteobacteria and most closely related to Geoalkalibacter ferrihydriticus Z-0531T (95.8 %), Desulfuromonas palmitatis SDBY1T (92.5 %) and ‘Desulfuromonas michiganensis’ BB1 (92.4 %). On the basis of phenotypic and phylogenetic differences, the novel strain is proposed to represent a novel species, Geoalkalibacter subterraneus sp. nov. (type strain Red1T=JCM 15104T=KCTC 5626T).", }
