Cells of strain Jyi-02T were aerobic, Gram-stain-negative, rod-shaped, non-motile and formed yellowish orange coloured colonies. Growth occurred at 10–40 °C (optimum, 20 °C) and pH 5.0–9.0 (optimum, pH 7.0) and in the presence of 0–1.0 % NaCl (optimum, 0 %, w/v). The major fatty acids (>10 %) of strain Jyi-02T were C18 : 1ω7c, summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c) and C14 : 0 2-OH. The polar lipid profile consisted of a mixture of phosphatidylethanolamine, phosphatidylglycerol, phosphatidylcholine, diphosphatidylglycerol, phosphatidyldimethylethanolamine, sphingoglycolipid, an uncharacterized phospholipid and an uncharacterized lipid. The major polyamine was spermidine. The major isoprenoid quinone was Q-10. The DNA G+C content was 64.8 mol%. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain Jyi-02T belonged to the genus Novosphingobium and had closest phylogenetic similarity to Novosphingobium soli CC-TPE-1T (97.8 %). The DNA–DNA relatedness of strain Jyi-02T with respect to valid published species of the genus Novosphingobium was less than 35 %. Phenotypic characteristics of the novel strain also differed from those of the closest related species of the genus Novosphingobium . On the basis of the genotypic, chemotaxonomic and phenotypic data, strain Jyi-02T represents a novel species in the genus Novosphingobium , for which the name Novosphingobium arvoryzae sp. nov. is proposed. The type strain is Jyi-02T (=BCRC 80537T=KCTC 32422T). %U https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.002756
