ABSTRACT
A novel Gram-stain-positive, strictly aerobic, endospore-forming, rod-shaped bacterial strain 7578-24T was isolated from ripened Pu'er tea. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain 7578-24T clustered with species of the genus Pullulanibacillus in the family Sporolactobacillaceae with 97.8-95.2 % sequence similarities, and was most closely related to Pullulanibacillus pueri YN3T with 97.8 % 16S rRNA gene sequence similarity. The DNA-DNA relatedness value between strain 7578-24T and P. pueri YN3T was 35 %. Strain 7578-24T had a cell-wall type A1γ peptidoglycan with meso-diaminopimelic acid as the diagnostic diamino acid. The major menaquinone was menaquinone 7 (MK-7). C18 1ω7c (45.4 %), anteiso-C17 0 (30.6 %) and anteiso-C15 0 (10.1 %) were the predominant fatty acids, and diphosphatidylglycerol, phosphatidylglycerol, five unknown phospholipids and one unknown aminolipid were the major polar lipids. The DNA G+C content of strain 7578-24T was 45.2 mol%. Strain 7578-24T could be differentiated from other related species of the genus Pullulanibacillus based on phenotypic characteristics, chemotaxonomic differences, phylogenetic analysis and DNA-DNA hybridization data. On the basis of polyphasic evidence from this study, a novel species of the genus Pullulanibacillus named Pullulanibacillus camelliae sp. nov. is proposed, with strain 7578-24T (=CGMCC 1.15371T=JCM 31236T) as the type strain.
