ABSTRACT
Four mesophilic and Gram-stain-positive strains (zg-686T/zg-691 and HY186T/HY189) isolated from Tibetan Plateau wildlife (PR China) belong to the genus Gordonia according to 16S rRNA gene and genomic sequence-based phylogenetic/genomic results. They have a DNA G+C content range of 67.4-68.3 mol% and low DNA relatedness (19.2-27.6â%) with all available genomes in the genus Gordonia. Strains zg-686T/zg-691 and HY186T/HY189 had C18ââ1ω9c, C18ââ0 10-methyl, C16ââ1 ω7c/C16ââ1ω6c and C16ââ0 as major cellular fatty acids. The polar lipids detected in strains zg-686T and HY186T included diphosphatidylglycerol, phosphatidylethanolamine, phosphatidyl inositol mannoside and phosphatidylinositol. The respiratory quinones comprised MK8(H2) (10.8â%) and MK9(H2) (89.2â%) for strain zg-686T, and MK6 (7.7â%), MK8(H2) (8.4â%), MK8(H4) (3.1â%) and MK9(H2) (80.8â%) for strain HY186T. Optimal growth conditions were pH 7.0, 35-37 °C and 0.5-1.5â% NaCl (w/v) for strains pair zg-686T/zg-691, and pH 7.0, 28 °C and 1.5â% (w/v) NaCl for strains pair HY186T/HY189. Based on these genotypic and phenotypic results, these four strains could be classified as two different novel species in the genus Gordonia, for which the names Gordonia jinghuaiqii sp. nov. and Gordonia zhaorongruii sp. nov. are proposed. The type strains are zg-686T (=GDMCC 1.1715T =JCM 33890T) and HY186T (=CGMCC 4.7607T =JCM 33466T), respectively.
