Article Description

A Gram-reaction-negative, rod-shaped marine bacterium, designated MEBiC08158, was isolated from sediments collected from Taean County, Korea, near the Hebei Spirit tanker oil spill accident. 16S rRNA gene sequence analysis revealed that strain MEBiC08158 was closely related to Alcanivorax marinus R8-12 (99.5% similarity) but was distinguishable from other members of the genus Alcanivorax (93.7–97.1%). The DNA–DNA hybridization value between strain MEBiC08158 and A. marinus R8-12 was 58.4%. Growth of strain MEBiC08158 was observed at 15–43°C (optimum 37–40°C), at pH6.0–9.5 (optimum pH7.0–8.0) and with 0.5–16% NaCl (optimum 1.5–3.0%). The dominant fatty acids were C:, C: cyclo ω8c, C:, C:ω7c, C: 3-OH and summed feature 3 (comprising C: 2-OH and/or C:ω7c). Several phenotypic characteristics differentiate strain MEBiC08158 from phylogenetically close members of the genus Alcanivorax. Therefore, strain MEBiC08158 should be classified as representing a novel species of the genus Alcanivorax, for which the name Alcanivorax gelatiniphagus sp. nov. is proposed. The type strain is MEBiC08158 (=KCCM 42990=JCM 18425).
