Celerinatantimonas yamalensis sp. nov., a cold-adapted diazotrophic bacterium from a cold permafrost brine Shcherbakova, Viktoria and Chuvilskaya, Nataliya and Rivkina, Elizaveta and Demidov, Nikita and Uchaeva, Victoria and Suetin, Stanislav and Suzina, Nataliya and Gilichinsky, David,, 63, 4421-4427 (2013), doi = https://doi.org/10.1099/ijs.0.045997-0, publicationName = Microbiology Society, issn = 1466-5026, abstract= A facultatively anaerobic nitrogen-fixing bacterium, strain C7T, was isolated from a permafrost cryopeg on the Yamal Peninsula, Russia. Comparative analysis of 16S rRNA gene sequences revealed that this bacterium was closely related to Celerinatantimonas diazotrophica S-G2-2T with a similarity of 95.5 %. Strain C7T differed from Celerinatantimonas diazotrophica in its ability to hydrolyse gelatin and inability to use d-mannose, melibiose, l-rhamnose, myo-inositol, lactose, lactulose, d-mannitol, trehalose, dl-lactate, glycogen or l-proline as sole carbon sources. In addition, strain C7T grew over a temperature range of 0–34 °C with optimum growth at 18–22 °C. The whole-cell fatty acid profile included C16 : 0, C16 : 1ω7, C18 : 1ω7, C17 cyclo and summed feature 2 [comprising C12 : 0 aldehyde and/or unknown fatty acid 10.913 (MIDI designation) and/or iso-C16 : 1/C14 : 0 3-OH]. The DNA G+C content was 44.7 mol%. Strain C7T is thus considered to represent a novel species, for which the name Celerinatantimonas yamalensis sp. nov. is proposed. The type strain is C7T ( = VKM B-2511T = DSM 21888T)., language=, type=
