从柽柳叶片中分离到一株革兰氏阴性杆菌F01 T。该分离物在30 °C、pH 7.0和5.0%（w/v）NaCl下生长最佳，并且显示出对锰、铅、镍、亚铁离子和铜离子的高耐受性。 主要脂肪酸为C18：1ω 7 c和C16：0，主要呼吸醌为Q-9。 极性脂质主要为二磷脂酰甘油、磷脂酰乙醇胺、磷脂酰甘油、未鉴定的氨基糖脂和磷脂。DNA G+C含量为65.8%。 多位点系统发育分析表明，F01 T菌株属于盐生菌属，与周边毛盐生菌（Salinicola peritrichatus）的16 S rRNA基因序列相似性最高（97.7%）。 F01 T菌株与盐生菌近缘菌株的DNA-DNA杂交率远低于70%。 根据表型、遗传学和化学分类学数据，菌株F01 T被认为是盐生菌属中的一个新种，并建议将其命名为Salinicola tamararisp. nov.。模式菌株为F01 T（=CCTCC AB 2015304 T =KCTC 42855 T）。
A Gram-stain-negative, rod-shaped bacterium, strain F01T, was isolated from leaves of Tamarix chinensis Lour. The isolate grew optimally at 30 °C, at pH 7.0 and with 5.0 % (w/v) NaCl, and showed a high tolerance to manganese, lead, nickel, ferrous ions and copper ions. The major fatty acids were C18 : 1ω7c and C16 : 0, and the predominant respiratory quinone was Q-9. Polar lipids were dominated by diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, unidentified aminoglycolipids and phospholipids. The DNA G+C content was 65.8 %. Based on multilocus phylogenetic analysis, strain F01T belonged to the genus Salinicola, with highest 16S rRNA gene sequence similarity to Salinicola peritrichatus CGMCC 1.12381T (97.7 %). The level of DNA-DNA hybridization between strain F01T and closely related Salinicola strains was well below 70 %. According to the phenotypic, genetic and chemotaxonomic data, strain F01T is considered to represent a novel species in the genus Salinicola, for which the name Salinicola tamaricis sp. nov. is proposed. The type strain is F01T (=CCTCC AB 2015304T=KCTC 42855T).
