Strain R2A43-10T was isolated from a greenhouse soil in Korea. Cells were Gram-negative rods, motile by means of a single flagellum. Growth occurred at 10–40 °C and at pH 5–8. Ubiquinone-8 (Q-8) was the only respiratory lipoquinone. Major fatty acids were summed feature 3 (C16 : 1ω7c and/or iso-C15 : 0 2-OH) and C16 : 0. 16S rRNA gene sequence analysis revealed that strain R2A43-10T was closely related to Chitinimonas taiwanensis cfT (sequence similarity of 94.8 %), but it exhibited low sequence similarities (<92 %) to other members of the Betaproteobacteria. The G+C content of the genomic DNA of strain R2A43-10T was 65.0 mol%. The novel isolate could be differentiated from C. taiwanensis cfT by several physiological properties. On the basis of genomic and phenotypic data, it is concluded that R2A43-10T (=KACC 11467T=DSM 17726T) is the type strain of a novel species of the genus Chitinimonas, for which the name Chitinimonas koreensis sp. nov. is proposed.
