Cells were straight rods, motile by a subpolar flagellum. Spores were formed in old cultures. Inner gas vacuoles swelled the cells when exposed to air. The optimum growth conditions were 55 °C, pH 7·5 and 1 % NaCl. Yeast extract was required for growth. Strain MET79T fermented several sugars, some organic acids and Casamino acids. Glucose was fermented into lactate, acetate, butyrate, H2 and CO2. Strain MET79T reduced thiosulfate to hydrogen sulfide and nitrate to ammonium. The DNA G+C content was 30·9 mol%. The closest phylogenetic relative of strain MET79T was Caloranaerobacter azorensis (88·7 % 16S rDNA sequence similarity). As strain MET79T (=DSM 15102T=CIP 107615T) was physiologically and phylogenetically different from its closest relatives, it is assigned as the type strain of a novel species of a new genus, Garciella nitratireducens gen. nov., sp. nov., language=, type=
