Abstract A novel psychrotolerant bacterium, strain ISLP-3T, was isolated from a sample of naturally formed ice sculpture on the shore of Lake Podprudnoye in Antarctica. Cells were motile, stained Gram-positive, non-spore-forming, straight or slightly curved rods with the shape of a baseball bat. The new isolate was facultatively anaerobic and catalase-positive. Growth occurred at 3-35 °C with an optimum at 22-24 °C, 0-2 % (w/v) NaCl with an optimum at 0.3 % and pH 6.2-9.5 with an optimum at pH 7.5. Strain ISLP-3T grew on several carbon sources, with the best growth on cellobiose. The isolate possessed ureolytic activity but growth was inhibited by urea. The strain was sensitive to: ampicillin, gentamycin, kanamycin rifampicin, tetracycline and chloramphenicol. Major fatty acids were: anteiso-C15 : 0, iso-C16 : 0, C16 : 0, C14 : 0 and iso-C15 : 0. The predominant menaquinone was MK-9(H4). The genomic G+C content was 69.5 mol%. The 16S rRNA gene showed 99 % sequence similarity to that of Sanguibacter suarezii ST-26T, but their recA genes shared ≤91 % sequence similarity, suggesting that this new isolate represents a novel species within the genus Sanguibacter. This conclusion was supported by average nucleotide identity, which was ≤91 % to the most closely related strain. The name Sanguibacter gelidistatuariae sp. nov. is proposed for the novel species with the type strain ISLP-3T=ATCC TSD-17T=DSM 100501T=JCM 30887T). The complete genome draft sequence of ISLP-3T was deposited under IMG OID 2657245272. Emendments to the descriptions of related taxa have been made based on experimental data from our comparative analysis.
