Interpretive Summary: This manuscript reports on the characterization of a new species of bacteria, Paraliobacillus 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 Gram-strain-positive, facultatively anaerobic, motile, endospore-forming, moderately halophilic bacterium, designated strain 126C4**T, was isolated from sediment of the East China Sea. The strain was catalase-positive and oxidase-negative. Optimal growth occurred at 28–30 deg C, pH 7.0–7.5 and in the presence of 3–5% (w/v) NaCl. The DNA G+C content was 39.6 mol%. The strain contained MK-7 as the sole respiratory quinone; ai-C15:0, C16:0, i-C15:0, and i-C16:0 as the major cellular fatty acids; and its polar lipid pattern consisted of iphosphatidylglycerol, phosphatidylethanolamine, three glycolipids, and four unknown phospholipid. Phylogenetic analyses based on 16S rRNA gene sequence comparisons showed that strain 126C4**T was a member of the genus Paraliobacillus, with 16S rRNA gene sequence similarity to the type strains of the two described species of the genus, Paraliobacillus quinghaiensis DSM 15857**T (sequence similarity 96.2 %) and Paraliobacillus ryukyuensis DSM 15140**T (sequence similarity 95.3 %). On the basis of its phylogenetic position, phenotypic traits, and chemotaxonomic characteristics it is supported that strain 126C4**T represents a novel species of genus Paraliobacillus, for which the name Paraliobacillus sediminis sp. nov. is proposed. The type strain is 126C4**T (=KCTC 33762**T).
