Higher similarity (96.6 %) was shared with ‘Desulfobacterium corrodens’ IS4, but this name has not been validly published. The affiliation of strain JS_SRB250LacT to the genus Desulfopila was further supported by analysis of aprBA gene sequences and shared physiological characteristics, in particular the broad range of organic electron donors used for sulfate reduction. Compared with Desulfopila aestuarii MSL86T, strain JS_SRB250LacT additionally utilized butyrate and succinate and grew chemolithoautotrophically with hydrogen as an electron donor. CO dehydrogenase activity was demonstrated, indicating that the reductive acetyl-CoA pathway (Wood–Ljungdahl pathway) was used for CO2 fixation. Results of cellular fatty acid analysis allowed chemotaxonomic differentiation of strain JS_SRB250LacT from Desulfopila aestuarii MSL86T by the presence of C17 : 0 cyclo and the absence of hydroxy and unsaturated branched-chain fatty acids. Based on phylogenetic, physiological and chemotaxonomic characteristics, strain JS_SRB250LacT represents a novel species of the genus Desulfopila, for which the name Desulfopila inferna sp. nov. is proposed. The type strain is JS_SRB250LacT (=DSM 19738T =NBRC 103921T)., language=, type=
