Advenella mandrilli sp. nov., a bacterium isolated from the faeces of Mandrillus sphinx

A novel Gram-negative strain WQ 585 T , isolated from the faeces of mandrills ( Mandrillus sphinx ) collected at Yunnan Wild Animal Park, Yunnan province, China, was subjected to a polyphasic taxonomic study. Phylogenetic analysis based on 16S rRNA gene sequences showed that the isolate belongs to the genus Advenella , sharing 98.5% and 98.2% sequence similarity with the type strain Advenella alkanexedens LAM0050 T and Advenella faeciporci M-07 T , respectively. The predominant ubiquinone was Q-8. The major cellular fatty acids (> 10%) were C 16:0, C 17:0 cyclo and Summed Feature 2. The G + C content of the genomic DNA of strain WQ 585 T was 49.0%. The whole genome average nucleotide identity (gANI) values of strain WQ 585 T with strain A. alkanexedens LAM0050 T and A. faeciporci M-07 T were 86.7% and 86.7%, and the digital DNA–DNA hybridization values of strain WQ 585 T with strain A. alkanexedens LAM0050 T and A. faeciporci M-07 T were 64.5% and 62.5%, respectively. Growth occurred at 10–45 °C (optimally at 20–30 °C), pH 6.0–9.0 (optimally at pH 7.0), and 0–5% (w/v) NaCl (optimally at 0.5–2.0%). On the basis of the taxonomic evidence, a novel species, Advenella mandrilli sp. nov., is proposed. The type strain is WQ 585 T (= KCTC 82396 T = CCTCC AA 2020028 T ).
