sp. nov., isolated from sediment.

A novel yellow-pigmented bacterial strain, designated YZ-48, was isolated from the sediment of the Yangtze River, PR China. Cells were Gram-stain-negative, non-motile, rod-shaped, strictly aerobic, catalase-positive and oxidase-positive. The strain grew optimally on R2A medium at 37 °C, pH 7.0 and with 1.0 % (w/v) NaCl. Strain YZ-48 showed the closest 16S rRNA gene sequence similarity to SE-s27 (96.4 %) and DSM 25687 (96.2 %). The phylogenetic trees based on 16S rRNA gene sequences showed that strain YZ-48 belonged to the genus but formed a distinct phylogenetic lineage. The obtained average nucleotide identity and digital DNA-DNA hybridization values between YZ-48 and the two closest strains were 75.0 and 74.5 % and 19.6 and 19.0 %, respectively. The sole respiratory quinone was MK-6. The major polar lipids were phosphatidylethanolamine, two unidentified aminolipids and three unidentified polar lipids. The major cellular fatty acids were iso-C, iso-C, iso-C G, iso-C 3-OH, iso-C 3-OH and iso-C 3-OH. The DNA G+C content was 40.2 mol%. Based on the phenotypic, chemotaxonomic, phylogenetic and genomic data, strain YZ-48 represents a novel species of the genus , for which the name sp. nov. is proposed, with strain YZ-48 (=KCTC 82329=CCTC AB 2023061=MCCC 1K08804) as the type strain.
