A novel bacterium, strain blls-2(T) was isolated from Pu'er tea. The isolate was Gram-positive, endospore-forming motile rod that grew at 15 approximately 42 degrees C and pH 6.0 approximately 10.2. The DNA G+C content was 48.3 mol%, the predominant isoprenoid quinone was MK-7, and the predominant cellular fatty acid was anteiso-C15:0 (54.2%) followed by C16:0 (15.5%) and iso-C16:0 (8.2%). The polar lipid pattern of blls-2(T) was characterized by the presence of diphosphatidylglycerol, phosphatidylethanolamine, and phosphatidylglycerol. Phy-logenetic analysis based on 16S rRNA gene sequence showed that the strain was affiliated within the Paenibacillaceae. The strain was most closely related to Paenibacillus granivorans A30(T), with a similarity of 97.1%. Based on the phylogenetic and phenotypic characteristics of strain blls-2(T), the isolate is thought to represent a novel taxon in the genus Paenibacillus. The name Paenibacillus camelliae sp. nov. is proposed for the fermented tea isolate; the type strain is blls-2(T) (= KCTC 13220(T)= CECT 7361(T)).
从普洱茶中分离出一种新型细菌,菌株blls-2(T)。该分离株为革兰氏阳性、形成芽孢的运动杆菌,在15至42摄氏度和pH值6.0至10.2的条件下生长。DNA G+C含量为48.3 mol%,主要类异戊二烯醌为MK-7,主要细胞脂肪酸为anteiso-C15:0(54.2%),其次是C16:0(15.5%)和iso-C16:0(8.2%)。blls-2(T)的极性脂质模式的特征是存在二磷脂酰甘油、磷脂酰乙醇胺和磷脂酰甘油。基于16S rRNA基因序列的系统发育分析表明,该菌株隶属于芽孢杆菌科。该菌株与食谷芽孢杆菌A30(T)关系最为密切,相似度为97.1%。基于菌株blls-2(T)的系统发育和表型特征,该分离株被认为代表芽孢杆菌属中的一个新分类单元。提议将从发酵茶中分离出的菌株命名为茶芽孢杆菌(Paenibacillus camelliae sp. nov.);模式菌株为blls-2(T)(=KCTC 13220(T)=CECT 7361(T))。
