GORDONA HYDROPHOBICA SP-NOV, ISOLATED FROM BIOFILTERS FOR WASTE-GAS TREATMENT

The taxonomic position of Gordona sp, strain DSM 44015(T), 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 (H-2), 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 44015(T) represents a new species within the genus Gordona for which the name Gordona hydrophobica is proposed.
