A bacterial strain, designated $GR24-5^T$, was isolated from soil cultivated with Korean ginseng. Cells were Gram-negative, strictly aerobic, catalase- and oxidase-positive, non-spore-forming motile rods. Based on the 16S rRNA gene sequence, strain $GR24-5^T$ could be assigned to the family Alcaligenaceae. Strain $GR24-5^T$ showed the highest sequence similarities with Parapusillimonas granuli $Ch07^T$ (97.1%), Pusillimonas noertemannii $BN9^T$ (96.9%), Pigmentiphaga kullae DSM $13608^T$ (96.5%), and Castellaniella defragrans $54Pin^T$ (96.3%). Strain $GR24-5^T$ demonstrated a low DNA-DNA relatedness (23%) with P. granuli $Ch07^T$. The major respiratory quinone is ubiquinone 8 (Q-8) and the major fatty acids are $C_{16:0}$, $C_{17:0}$ cyclo, and summed feature 1 ($C_{14:0}$ 3-OH/iso-$C_{16:1}$ I/$C_{12:0}$ alde). Putrescine, spermidine, and 2-hydroxyputrescine are the major polyamines. The major polar lipids are phosphatidylmethylethanolamine, phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, and an unknown aminophospholipid. Polar lipid patterns of strain $GR24-5^T$ were unique in having a large amount of phosphatidylmethylethanolamine. Based on phylogenetic analysis and physiological and biochemical characteristics, strain $GR245^T$ represents a novel genus and species, for which the name Paralcaligenes ureilyticus gen. nov., sp. nov. is proposed. The type strain of P. aralcaligenes ureilyticus is $GR24-5^T$ (=KACC $13888^T$ =DSM $24591^T$).
