An aerobic, Gram-negative, motile bacterium, strain C02, was isolated from seawater obtained from Semarang Port in Indonesia. Cells of strain C02 were peritrichously flagellated and rod-shaped. Strain C02 was able to degrade naphthalene, alkylnaphthalenes and phenanthrene. 16S rRNA gene sequence analysis revealed that this strain was affiliated with the family in the class and was related most closely to FF3 (95.7 % similarity) and JC2049 (95.2 %). The DNA G+C content of strain C02 was 64.6 mol%. The major cellular fatty acids were C 7 (50.9 % of the total), C (17.9 %), 11 methyl C 7 (14.7 %), C 9 (2.9 %) and C cyclo 8 (2.4 %), and the predominant respiratory lipoquinone was ubiquinone-10. Based on physiological, chemotaxonomic and phylogenetic data, strain C02 is suggested to represent a novel species of a new genus, for which the name gen. nov., sp. nov. is proposed. The type strain of is C02 (=JCM 14838=DSM 19561).
