A Gram-positive, rod-shaped, strictly aerobic, spore-forming, moderately halophilic bacterium, designated strain SSK2-2T, was isolated from fermented shrimp paste (ka-pi) produced in Thailand. It contained MK-7 as the predominant menaquinone and meso-diaminopimelic acid in the cell-wall peptidoglycan. The isolate grew at 8-43 °C, pH 6-9 and in 0.5-24% (w/v) NaCl (optimum, 6-14% NaCl). The major cellular fatty acids were anteiso-C15:0 and anteiso-C17:0. Phosphatidylglycerol and diphosphatidylglycerol were the major polar lipid components. The DNA G+C content was 39.7 mol%. Comparative 16S rRNA gene sequence analyses showed that strain SSK2-2T was most closely related to Oceanobacillus picturae KCTC 3821T with 98.7% sequence similarity. Based on phenotypic and molecular features combined with DNA-DNA hybridization results (≤24.9% with O. picturae KCTC 3821T), this strain represents a novel species of the genus Oceanobacillus for which the name Oceanobacillus kapialis sp. nov. is proposed; the type strain is SSK2-2T (=KCTC 13177T=PCU 300T=TISTR 1858T).
