A Gram-negative-staining, rod-shaped bacterium, designated strain SY01T, was isolated from tidal flat sediment from Sacheon Bay, South Korea. Strain SY01T was characterized with respect to its phenotypic and phylogenetic characteristics. The novel strain was spore-forming, motile, catalase-negative and oxidase-positive. Optimal growth of the strain occurred at 30 °C and pH 7.0. The DNA G+C content was 56.1 mol%. The predominant menaquinone was MK-7. Diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and several unknown lipids were detected in the polar lipid profile. Anteiso-C15 : 0 (47.2 %), iso-C15 : 0 (18.9 %) and iso-C16 : 0 (10.5 %) were the major cellular fatty acids of strain SY01T. The highest 16S rRNA gene sequence similarities were found with Paenibacillus phyllosphaerae PALXIL04T (95.9 %), Paenibacillus tarimensis SA-7-6T (94.6 %) and Paenibacillus mendelii C/2T (94.4 %). Based on the phylogenetic, chemotaxonomic and physiological characteristics presented in this study, strain SY01T represents a novel species of the genus Paenibacillus, for which the name Paenibacillus sacheonensis sp. nov. is proposed. The type strain is SY01T ( = DSM 23054T = KACC 14895T).
