A Gram-stain-negative, short rod-shaped and light-red-pigmented bacterium, designated XAAS-1T, was isolated from the soil of Aydingkol Lake near the Turpan City, Xinjiang, China. The isolate was positive for oxidase, catalase and hydrolysis of starch, casein, gelatin and aesculin. The sole respiratory quinone was MK-7 and the principal cellular fatty acids were iso-C15 : 0 and C15 : 0 3-OH. The major polar lipids were phosphatidylethanolamine, one unidentified phospholipid and two unidentified polar lipids. The polyamine pattern was found to contain mainly sym-homospermidine. 16S rRNA gene sequence analysis indicated that strain XAAS-1T belongs to the genus Pontibacter in the family Cytophagaceae, with sequence similarities ranging from 93.8 to 96.7 % with other type species of the genus Pontibacter. On the basis of phenotypic and genotypic data, strain XAAS-1T represents a novel species of the genus Pontibacter, for which the name Pontibacter aydingkolensis sp. nov. (type strain XAAS-1T=CCTCC AB 2016134T=JCM 31442T) is proposed.
从中国新疆吐鲁番市附近艾丁湖的土壤中分离出一株革兰氏阴性、短杆状且呈浅红色色素的细菌，命名为XAAS-1T。该分离株氧化酶、过氧化氢酶阳性，能水解淀粉、酪蛋白、明胶和七叶苷。唯一的呼吸醌为MK-7，主要的细胞脂肪酸为异C15 : 0和C15 : 0 3-OH。主要的极性脂为磷脂酰乙醇胺、一种未鉴定的磷脂和两种未鉴定的极性脂。发现多胺模式主要包含共生高亚精胺。16S rRNA基因序列分析表明，菌株XAAS-1T属于噬纤维菌科的Pontibacter属，与Pontibacter属的其他模式种的序列相似性为93.8%至96.7%。基于表型和基因型数据，菌株XAAS-1T代表Pontibacter属的一个新物种，为此提出Pontibacter aydingkolensis sp. nov.（模式菌株XAAS-1T = CCTCC AB 2016134T = JCM 31442T）这一名称。
