It grew at the temperature range 10–37 °C (optimum, 28 °C) and pH range 6.0–9.0 (optimum, pH 7.0), and tolerated up to 2 % (w/v) NaCl. According to 16S rRNA gene sequence analysis, strain T16R-86T shared the highest similarity with Chitinophaga barathri YLT18T (96.8 %) and C. pinensis DSM 2588T (96.7 %), forming a subcluster with C. barathri YLT18T, C. cymbidii R156-2T and C. niabensis JS13-10T in the phylogenetic tree. The major fatty acids were iso-C15 : 0, C16 : 1ω5c and iso-C17 : 0 3-OH. The predominant respiratory quinone was menaquinone MK-7. Polar lipids were phosphatidylethanolamine, five unknown aminolipids, an unknown aminophospholipid, one unknown phospholipid and two unknown lipids. The DNA G+C content was 53.6 mol%. The phenotypic, chemotaxonomic and phylogenetic data showed that strain T16R-86T represents a novel species of the genus Chitinophaga , for which the name Chitinophaga rhizosphaerae sp. nov. is proposed. The type strain is T16R-86T (=KACC 18790T=JCM 31600T)., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.002134
