Abstract:
A new member of the family Flavobacteriaceae was isolated from the biofilm of a stone at Nordstrand, a peninsula at the German North Sea shore. Phylogenetic analysis of the 16S rRNA gene sequence showed that strain ANORD1 T was most closely related to the validly described type strains Polaribacter porphyrae LNM-20 T (97.0 %) and Polaribacter reichenbachii KMM 6386 T (96.9 % 16S rRNA gene sequence similarity) and clustered with Polaribacter gangjinensis K17-16 T (96.0 %). Strain ANORD1 T was determined to be mesophilic, Gram-negative, non-motile and strictly aerobic. Optimal growth was observed at 20–30 °C, within a salinity range of 2–7 % sea salt and from pH 7–10. Like other type strains of the genus Polaribacter , ANORD1 T was tested negative for flexirubin-type pigments, while carotenoid-type pigments were detected. The DNA G+C content of strain ANORD1 T was 30.6 mol%. The sole respiratory quinone detected was menaquinone 6 (MK-6). The major fatty acids identified were C 15 : 0 , iso-C 15 : 0 , C 15 : 1 ω6 c and iso-C 15 : 0 3-OH. Based on the polyphasic approach, strain ANORD1 T represents a novel species in the genus Polaribacter , with the name Polaribacter septentrionalilitoris sp. nov. being proposed. The type strain is ANORD1 T (=DSM 110039 T =NCIMB 15081 T =MTCC 12685 T ).
