A Gram-negative, aerobic, mesophilic, non-spore-forming, chemotrophic, chlorophyll-lacking, nitrogen-fixing bacterium, designated strain USBA 355T, was isolated from the saline spring 'Salado de Consot᧠situated in the Colombian Andes. The non-flagellated cells of strain USBA 355T were straight to slightly curved rods (0.6-0.7 x 3.0-3.5 孩. Growth occurred optimally at 30 à(growth temperature range between 20 and 40 é, at pH 6.5-6.7 (pH growth range between 5.0 and 8.0) and at 0.5 % NaCl (w/v) (range between 0 and 4 %). The major quinone present was Q-10 and the predominant fatty acids identified were C19 : 0 cyclo 8c, C18 : ...

The major quinone present was Q-10 and the predominant fatty acids identified were C19 : 0 cyclo 8c, C18 : 17c and C18 : 0. The G+C content of the chromosomal DNA was 71ᱠmol%. 16S rRNA gene sequence analysis indicated that strain USBA 355T formed a distant phylogenetic line of descent with members of the genus Thalassobaculum, family Rhodospirillaceae, class Alphaproteobacteria (90 % gene sequence similarity). Comparison of the phylogenetic, chemotaxonomic and physiological features of strain USBA 355T with all other members of the family Rhodospirillaceae suggested that it represents a novel genus and species for which the name Tistlia consotensis gen. nov., sp. nov. is proposed. The type strain of the type species is USBA 355T (=JCM 15529T=KCTC 22406T).
