A novel bacterium, PB3-7BT, was isolated on phenol-supplemented inorganic growth medium from a laboratory-scale wastewater purification system that treated coke plant effluent. 16S rRNA gene sequence analysis revealed that strain PB3-7BT belonged to the family Alcaligenaceae and showed the highest pairwise sequence similarity to Parapusillimonas granuli Ch07T (97.5 %), Candidimonas bauzanensis BZ59T (97.3 %) and Pusillimonas noertemannii BN9T(97.2 %). Strain PB3-7BT was rod-shaped, motile and oxidase- and catalase-positive. The predominant fatty acids were C16:0, C17:0 cyclo, C19:0 cyclo ω8cand C14:0 3-OH, and the major respiratory quinone was Q-8. The G+C content of the genomic DNA of strain PB3-7BT was 59.7 mol%. The novel bacterium can be distinguished from closely related type strains based on its urease activity and the capacity for assimilation of glycerol and amygdalin. On the basis of the phenotypic, chemotaxonomic and molecular data, strain PB3-7BTis considered to represent a new genus and species, for which the name Eoetvoesia caeni gen. nov., sp. nov. is proposed. The type strain of Eoetvoesia caeni is PB3-7BT (= DSM 25520T = NCAIM B 02512T).
