JF International Journal of Systematic and Evolutionary Microbiology, VO 67 IS 9 SP 3458 OP 3461 DO https://doi.org/10.1099/ijsem.0.002137 PB Microbiology Society, SN 1466-5034, AB A novel Gram-stain-negative, chemolithoautotrophic sulfur oxidizer, strain JG42T, was isolated from a hot spring microbial mat. As an electron donor for autotrophic growth, strain JG42T utilized sulfide, thiosulfate, tetrathionate and elemental sulfur. Cells of strain JG42T were oxidase-positive and catalase-negative. The G+C content of the genomic DNA was 65 mol%. The predominant cellular fatty acid was C16 : 0. Phylogenetic analysis of the 16S rRNA gene indicated that strain JG42T belonged to the order Chromatiales , but sequence similarities to the known species were less than 94 %. On the basis of its properties, strain JG42T (=DSM 104776T=NBRC 112696T) is proposed as the type strain of a novel species of a new genus, Sulfurivermis fontis gen. nov., sp. nov., which belongs to the family Thioalkalispiraceae. A new family, Thioprofundaceae fam. nov., is also proposed to accommodate the genus Thioprofundum , transferred from the family Thioalkalispiraceae ., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.002137
