Gordonia rhizosphera sp. nov. isolated from the mangrove rhizosphere

The taxonomic position of bacterial strain 141T, isolated from the mangrove rhizosphere, has been clarified by phenotypic, chemotaxonomic and phylogenetic studies. The strain possesses wall chemotype IV, MK-9(H2) as the predominant menaquinone, relatively long-chain mycolic acids (56–64 carbon atoms) and straight-chain saturated and monounsaturated fatty acids with a small amount of tuberculostearic acid. The G+C content of the DNA is 66.8 mol%. Similarity values for genes encoding 16S rRNA indicated that strain 141Trepresents a new species within the genus Gordonia for which the name Gordonia rhizosphera sp. nov. is proposed. The type strain of G. rhizosphera is 141T(= IFO 16068T).
