A Gram-stain-positive, spore-forming, motile, strictly aerobic, rod-shaped bacterium, designated strain L5 T , was isolated from soil of Tenglong cave, China. 16S rRNA gene sequence analysis showed that strain L5 T was related most closely to Bacillus asahii MA001 T (96.5 %) (the highest 16S rRNA gene sequence similarity), Bacillus kribbensis BT080 T (96.4 %) and Bacillus deserti ZLD-8 T (96.2 %). The DNA G+C content of strain L5 T was 45.6 mol%. The major menaquinone was MK-7. The major fatty acids were iso-C 14 : 0 , anteiso-C 15 : 0 and iso-C 16 : 0 , and the major polar lipids were diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine. The diagnostic diamino acid in the cell-wall peptidoglycan was meso -diaminopimelic acid. In addition, strain L5 T had different characteristics compared with the other Bacillus strains such as pink colony colour, low growth temperature and low nutrient requirement. The results indicate that strain L5 T represents a novel species of the genus Bacillus , for which the name Bacillus cavernae sp. nov. is proposed. The type strain is L5 T ( = KCTC 33637 T = CCTCC AB 2015055 T ).
