Abstract

A yellow-pigmented, Gram-negative and aerobic bacterial strain, designated AT1026, was isolated from a terrestrial sample from the Antarctic. Results of 16S rRNA gene sequence analysis indicated that the Antarctic isolate belonged to the genus , with the highest sequence similarity to (96·4 %). Cells were non-motile, non-gliding and psychrotolerant, with optimum and maximum temperatures of about 20 and 25 °C. Flexirubins were absent. The major isoprenoid quinone (MK-6), predominant cellular fatty acids (iso-C G, iso-C and a mixture of C 7 and/or iso-C 2-OH) and DNA G+C content (38 mol%) of the Antarctic isolate were consistent with those of the genus . In contrast, several phenotypic characters can be used to differentiate this isolate from other flavobacteria. The polyphasic data presented in this study indicated that this isolate should be classified as a novel species in the genus . The name sp. nov. is therefore proposed for the Antarctic isolate; the type strain is AT1026 (=IMSNU 14042=KCTC 12222=JCM 12383).
