The cells were short rods, Gram-stain-negative, catalase- and oxidase-positive. Growth was observed with 0–12 % (w/v) NaCl, with optimal growth at 0.5–2 %, and at pH 6.0–9.0, with optimum of pH 7.0, and a growth temperature of 10–45 °C, with an optimum of 28–37 °C. Phylogenetic analysis based on the 16S rRNA gene placed N-1-3-6T in the genus Sinomicrobium with the closest relative being Sinomicrobium pectinilyticum 5DNS001T, exhibiting 95.3 % 16S rRNA pairwise similarity. A polyphasic taxonomic study, including phenotypic, chemotaxonomic and molecular analyses, was performed to clarify its taxonomic position. N-1-3-6T contained MK-6 as the predominant menaquinone. Polar lipids consisted of phosphatidylethanolamine and several unidentified aminolipids, phospholipids and lipids. The principal fatty acids (>10 %) were iso-C15 : 0 (26.9 %), summed feature 3 [C16 : ω7c/ω6c (17.2 %)] and iso-C17 : 0 3-OH (14.7 %). The DNA G+C content of N-1-3-6T was 47.7 mol%. On the basis of its phenotypic and genotypic properties, strain N-1-3-6T should be classified as representing a novel species of the genus Sinomicrobium , for which the name Sinomicrobium soli sp. nov. is proposed, with the type strain N-1-3-6T (=MCCC 1A06047T=KCTC 52339T)., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.003273
