Abstract

An aerobic, Gram-negative, non-fermentative, rod-shaped, motile, orange-pigmented bacterium, UST20020801, was isolated from sea-water samples collected from Port Shelter, Hong Kong, S.A.R., China, in August 2002. The full 16S rRNA gene sequence of this strain shared only 87·5 % similarity with its nearest relative, , a species of the family . However, strain UST20020801 possessed menaquinone-6, a major respiratory quinone of members of the family . This strain contains unique fatty acids such as i15 : 1G, i17 : 19, 2-OH 15 : 0, 15 : 16 and three unknown fatty acids of equivalent chain-length of 11·543, 13·565 and 16·582. Further analysis of its ecophysiology and biochemistry suggests that this strain represents a new genus in the phylum ‘’. The name gen. nov., sp. nov. is proposed. The type strain is UST20020801 (=NRRL B-23963=JCM 12287).
