The taxonomic position of Gordona sp. strain DSM 44015T, isolated from the packing material of a biofilter used for biological odor abatement of animal rendering emissions, has been clarified by a polyphasic study comprising chemotaxonomic, sequencing, and phenotypic results. The strain possesses a wall chemotype IV, MK-9 (H2), as the predominant menaquinone; relatively long-chain mycolic acids (54 to 62 carbon atoms); and straight-chain, saturated, and monounsaturated fatty acids with considerable amounts of tuberculostearic acid. The polar lipids include phosphatidylethanolamine, and the G+C content of the DNA is 69 mol%. Similarity values for genes encoding 16S rRNA indicate that Gordona sp. strain DSM 44015T represents a new species within the genus Gordona for which the name Gordona hydrophobica is proposed.
