Felföldi, T., Vengring, A., Kéki, Zs., Márialigeti, K., Schumann, P., Tóth, E.M. 2014. Eoetvoesia caeni gen. nov., sp. nov., isolated from an activated sludge system treating coke plant effluent. International Journal of Systematic and Evolutionary Microbiology, 64, 1920-1925.
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 v8c and 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 PB3-7BT is 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 (5DSM 25520T5NCAIM B 02512T).
