A bacterial strain designated YY287, isolated from food waste compost, was investigated by polyphasic taxonomic approach. The cells were rod-shaped, Gram-negative, non-pigmented, non-spore-forming and non-fermentative. Phylogenetic analyses using the 16S rRNA gene sequence showed that the strain formed a monophyletic branch towards the periphery of the evolutionary radiation occupied by the genus ; its closest neighbours were the type strains DSM 50244 (96.5 %), DSM 7099 (95.4 %), Dant 3-8 (95.2 %) and KCTC 12005 (94.6 %). Strain YY287 was clearly distinguished from all of these strains using phylogenetic analysis, DNA–DNA hybridization, fatty acid composition data and a range of physiological and biochemical characteristics. The major fatty acids were 16 : 0 (33 %), 18 : 17 (13 %) and summed feature 3 (16 : 17 and/or 15 : 0 iso 2-OH; 41 %). The DNA G+C content of the genomic DNA was 62.8 mol%. It is evident from the genotypic and phenotypic data that strain YY287 represents a novel species in the genus , for which the name sp. nov. is proposed. The type strain is YY287 (=BCRC 17659=LMG 24008).
