Abstract

gen. nov. is proposed for two aerobic, chemo-organotrophic, cyst-producing soil bacterial strains. These bacteria are Gram-negative, non-flagellated rods or cysts, isolated from subdesert soil in Tataouine, Tunisia. Phylogenetic analyses of the sequences of the two strains showed that they do not constitute a robust clade at the genus level with any previously described bacteria and that they are a deep branch of a clade also grouping the genera and within the -. They belong to two different species, as verified by DNA–DNA hybridization (23·5 % reassociation). The type species of the genus is sp. nov., with the type strain TTB310 (=DSM 14655 =ATCC BAA-407 =LMG 21543). The second species is sp. nov., with the type strain TMB834 (=DSM 14656 =ATCC BAA-408 =LMG 21542). The G+C contents of and are 69·6 and 66·6 mol%, respectively.
