Abstract
A novel hydrocarbon-degrading, Gram-negative, obligately aerobic, non-motile, non-sporulating, rod-shaped bacterium, designated strain TBF2/20.2T, was isolated from a biofilter clean-up facility set up on a hydrocarbon-contaminated site in Hungary. It was characterized by using a polyphasic approach to determine its taxonomic position. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the isolate is affiliated with the genus Olivibacter in the family SPHINGOBACTERIACEAE: It was found to be related most closely to Olivibacter ginsengisoli Gsoil 060T (93.3 % 16S rRNA gene sequence similarity). Strain TBF2/20.2T grew at pH 6–9 (optimally at pH 6.5–7.0) and at 15–42 °C (optimally at 30–37 °C). The major fatty acids were iso-C15 : 0 (39.4 %), summed feature 3 (iso-C15 : 0 2-OH and/or C16 : 1ω7c; 26.0 %), iso-C17 : 0 3-OH (14.5 %) and C16 : 0 (4.5 %). The major menaquinone was MK-7 and the predominant polar lipid was phosphatidylethanolamine. The DNA G+C content of strain TBF2/20.2T was 41.2 mol%. Physiological and chemotaxonomic data further confirmed the distinctiveness of strain TBF2/20.2T from recognized members of the genus OLIVIBACTER: Thus, strain TBF2/20.2T is considered to represent a novel species of the genus Olivibacter, for which the name Olivibacter oleidegradans sp. nov. is proposed. The type strain is TBF2/20.2T ( = NCAIM B 02393T = CCM 7765T).
