abstract= A novel bacterial strain, YC7001T, was isolated from the rhizosphere soil of rice collected at Jinju, Korea, and was characterized using a polyphasic approach. Cells of strain YC7001T were Gram-negative-staining, yellow-pigmented, rod-shaped, aerobic, heterotrophic and non-motile. Strain YC7001T grew optimally at 25–30 °C, pH 5.0–8.0 and degraded gelatin, cellulose and chitin. Phylogenetic analyses based on 16S rRNA gene sequences indicated that strain YC7001T belonged to the genus Chitinophaga in the family Chitinophagaceae . The most closely related species were Chitinophaga sancti NBRC 15057T (96.9 %), Chitinophaga ginsengisoli Gsoil 052T (95.9 %), Chitinophaga pinensis DSM 2588T (95.7 %), Chitinophaga filiformis IFO 15056T (95.7 %) and Chitinophaga niabensis JS13-10T (95.0 %). The DNA–DNA relatedness value of strain YC7001T with C. sancti NBRC 15057T was 15.2±0.6 %. Strain YC7001T contained MK-7 as the major menaquinone and homospermidine as the major polyamine. The major fatty acids of strain YC7001T were C15 : 0 iso, C16 : 1ω5c and C17 : 0 iso 3-OH. The polar lipids were phosphatidylethanolamine, unknown aminolipids and unknown lipids. The total genomic DNA G+C content was 41.3 mol%. On the basis of phenotypic, chemotaxonomic and phylogenetic analyses, strain YC7001T represents a novel species of the genus Chitinophaga , in the family Chitinophagaceae , for which the name Chitinophaga oryziterrae sp. nov. is proposed. The type strain is YC7001T ( = KACC 14533T = JCM 16595T).,
