A novel strain, YIM 100770(T), was isolated from Rhinoceros unicornis faeces collected from Yunnan Wild Animal Park, China. The taxonomic status was determined based on the physiological, biochemical and phylogenetic characteristics. Strain YIM 100770(T) was observed to be rod-shaped, nonmotile, Gram-stain negative and aerobic. The G+C content of the genomic DNA was determined to be 68.5 mol%. The cells of strain YIM 100770(T) contain ubiquinone Q-10 as the respiratory quinone. The major fatty acids (>1%) were identified as Summed feature 8 (C-18:1 omega 7c and/or C-18:1 omega 6c; 78.1%), Summed feature 4 (iso-C1(7:1)-I and/or anteiso-C-17:1-B; 12.9%), C-19:0 cyclo omega 8c (2.8%), C-16:0 (2.2%) and C-18:0 (2.2%). Comparison of 16S rRNA gene sequences revealed the strain show high similarities with the members of the genera Psychroglaciecola (94.5%), Methylobacterium (90.5-94.1%) and Microvirga (92.0-93.3%) in the family Methylobacteriaceae. In addition, the strain also showed high similarities with the members of the genera Chelatococcus (93.7-94.0%) and Pseudochelatococcus (93.1-93.7%) in the family Beijerinckiacea, and the genus Bosea (93.1-93.8%) in the family Bradyrhizobiaceae. The phylogenetic analysis, combined with the chemical characteristics, suggest that the strain represents a novel genus in the order Rhizobiales of the class Alphaproteobacteria, for which the name Enterovirga rhinocerotis gen. nov., sp. nov. is proposed. The type strain of E. rhinocerotis is YIM 100770(T) (=DSM 25903(T) = CCTCC AB 2012048(T)).
