• 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, non-motile, 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 ω 7 c and/or C 18:1 ω 6 c ; 78.1%), Summed feature 4 (iso-C 17:1 -I and/or anteiso-C 17:1 -B; 12.9%), C 19:0 cyclo ω 8 c (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 ).
