从中国赤水河茅台段淡水中分离到一株半透明、白色、革兰氏阴性、厌氧、无鞭毛、微弯或弯曲的细菌菌株，命名为YT 8（T）。细胞呈过氧化氢酶阳性和氧化酶阳性。16 S rRNA基因序列的系统发育分析表明，菌株YT 8（T）属于Arenimonas属，与该属其它成员的相似性为93.7%~ 95.0%。主要的类异戊二烯醌是泛醌8（Q-8），主要的极性脂质是磷脂酰乙醇胺，一种未鉴定的氨基脂质，两种未鉴定的磷脂和两种未鉴定的极性脂质，而主要的脂肪酸是异-C15：0，异-C14：0和antiso-C15：0。菌株YT 8（T）的DNA G+C含量为66.6mol%。通过对菌株YT 8（T）的表型、系统发育和基因型特征的研究，认为菌株YT 8（T）是沙单胞菌属的一个新种，并将其命名为茅台沙单胞菌Arenimonasmaotaiensissp. nov.。模式菌株为YT 8（T）（= CGMCC 1.12726（T）= JCM 19710（T））。
A translucent, white, Gram-reaction-negative, facultatively anaerobic, non-flagellated, slightly curved or curved bacterial strain, designated YT8(T), was isolated from the fresh water of the Maotai section of Chishui River, China. Cells were catalase-positive and oxidase-positive. Phylogenetic analyses of 16S rRNA gene sequences revealed that strain YT8(T) is a member of the genus Arenimonas with similarity to other members of this genus ranging from 93.7 to 95.0 %. The major isoprenoid quinone was ubiquinone 8 (Q-8), major polar lipids were phosphatidylethanolamine, one unidentified aminolipid, two unidentified phospholipids and two unidentified polar lipids, while major fatty acids were iso-C15 : 0, iso-C14 : 0 and anteiso-C15 : 0. The DNA G+C content of strain YT8(T) was 66.6 mol%. On the basis of phenotypic, phylogenetic and genotypic features studied, strain YT8(T) is suggested to represent a novel species of the genus Arenimonas, for which the name Arenimonas maotaiensis sp. nov. is proposed. The type strain is YT8(T) ( = CGMCC 1.12726(T) = JCM 19710(T)).
