Interpretive Summary: ARS researchers from Peoria, IL collaborated with scientists from Shandong University in Weihai, China to characterize a novel bacterium found in marine environment. This manuscript reports on the characterization of a new species of bacteria Wenzhouxiangella sediminis, that grows in high salt concentrations. This species possesses novel and unusual biochemical characteristics, which makes it attractive for various agricultural and biotechnological purposes. As such, this strain was accessioned into the Crop Bioprotection Research Unit’s culture collection where its potential for biological control applications can be assessed in future studies.

Technical Abstract: A novel Gram-stain-negative, non-spore-forming, no flagellum, facultatively anaerobic, oxidase-negative, catalase- positive, rod-shaped strain, designated XDB06**T, was isolated from coastal sediment of Xiaoshi Island, Weihai, China. Optimal growth occurred at 37 °C, pH 7.5 and with 4.0% (w/v) NaCl. Q-8 was the sole respiratory quinone. The major cellular fatty acids in strain XDB06**T were iso-C15:0 and iso-C16:0. The polar lipids of strain XDB06**T were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, two unidentified glycolipids and four unidentified phospholipids. The genomic DNA G+C content of the strain was 65.0 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain XDB06**T can be considered as a species within the genus Wenzhouxiangella, being most closely related to Wenzhouxiangella marina MCCC 1K00261**T, with a 16S rRNA gene sequence similarity of 96.50%. Based on data from the current polyphasic study, XDB06**T represents a novel species within the genus Wenzhouxiangella, for which the name Wenzhouxiangella sediminis sp. nov. is proposed. The type strain is XDB06**T (=KCTC 52041**T= MCCC 1K02285**T).
