【Abstract】A yellow-coloured, rod-shaped, Gram-reaction- and Gram-staining-negative, non-motile and aerobic bacterium, designated strain ZS1-8(T), was isolated from a sample of sandy intertidal sediment collected from the Antarctic coast. Flexirubin-type pigments were absent. In phylogenetic analyses based on 16S rRNA gene sequences, strain ZS1-8(T) formed a distinct phyletic line and the results indicated that the novel strain should be placed in a new genus within the family Flavobacteriaceae. In pairwise comparisons between strain ZS1-8(T) and recognized species, the levels of 16S rRNA gene sequence similarity were all <93.3 %. The strain required Ca(2+) and K(+) ions as well as NaCl for growth. Optimal growth was observed at pH 7.5-8.0, 17-19 °C and with 2-3 % (w/v) NaCl. The major fatty acids were iso-C(15 : 1) G, iso-C(15 : 0), summed feature 3 (iso-C(15 : 0) 2-OH and/or C(16 : 1)ω7c), an unknown acid with an equivalent chain-length of 13.565 and iso-C(17 : 0) 3-OH. The major respiratory quinone was MK-6. The predominant polar lipid was phosphatidylethanolamine. The genomic DNA G+C content was 43.9 mol%. Based on the phylogenetic, phenotypic and chemotaxonomic data, strain ZS1-8(T) represents a novel species in a new genus in the family Flavobacteriaceae for which the name Pricia antarctica gen. nov., sp. nov. is proposed. The type strain of the type species is ZS1-8(T) (= JCM 17291(T) = DSM 23421(T)).
