Strain SSH13T was oxidase-negative, catalase-positive and grew at 2–37 °C (optimum, 30 °C), in the presence of 0.5–6% NaCl and within a pH range of pH 6–10 (optimum, pH 8). The novel isolate required NaCl for growth and grew optimally with approximately 2 % NaCl. Chemotaxonomic and morphological characteristics were consistent with members of the genus Lewinella . Furthermore, phylogenetic analysis based on 16S rRNA gene sequencing revealed that strain SSH13T was most closely related to the type strains of the genus Lewinella . Strain SSH13T had highest 16S rRNA gene sequence similarities to Lewinella persica DSM 23188T (95.3 %) and Lewinella agarilytica KCTC 12774T (95.0 %). The major fatty acids of SSH13T were summed feature 3 (C16 : 1  ω7c and/or C16 : 1  ω6c) and iso-C15 : 0. Strain SSH13T contained phosphatidylethanolamine as a major polar lipid. Menaquinone-7 was the predominant respiratory quinone. The average nucleotide identity values between strain SSH13T and L. persica T-3T and L. agarilytica SST-19T were 72.9 and 72.6 %, respectively. The DNA G+C content of the genomic DNA was 52.8 mol%. The present study aimed to determine the multiple-antibiotic resistance ofthe novel bacterium. Based on phylogenetic and phenotypic analyses, strain SSH13T is considered to represent a novel species of the genus Lewinella , for which the name Lewinella aurantiaca sp. nov. (type strain SSH13T=KACC 21167T=NBRC 113866T) is proposed., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.004515
