从新疆维吾尔自治区中国的污水水样中分离到一株好氧、革兰氏阴性、无芽胞和耐寒细菌，命名为XJ109T。基于16S rRNA基因序列的系统发育分析表明，菌株XJ109Trea是黄杆菌科的一个新成员。该菌株与短链杆菌LMG 4011T的16S rRNA基因序列同源性为95.5%，与常文氏赤潮杆菌BY4T的16S rRNA基因序列的同源性为95.4%，与镰状芽孢杆菌NF993T的同源性为95.3%，与弱毒DSM 16922T的同源性为92.3%。菌株XJ109T具有黄杆菌科常见的表型特征和化学分类特征，其主要的呼吸酚为孟喹酮-6(MK-6)，主要脂肪酸为iso-C17：03OH和iso-C15：0。极性脂谱由磷脂酰乙醇胺、一个未鉴定的磷脂和两个未鉴定的脂类组成。基因组DNA G+C含量为38.0%。菌株XJ109T具有较强的过氧化氢酶和氧化酶活性，能在4~30℃(最适16~20℃)、pH 6.5~10.0(最适7.0~7.5)和含0~2.0%(w/v)氯化钠(最适0.5%)的条件下生长。根据现有的多相证据，XJ109T菌株被认为代表了黄杆菌科的一个新属和新种，命名为新江藻属。Nov.，sp.11月是提议的。模式菌株为XJ109T(=CGMCC 1.10229T=JCM 16590T)。
An aerobic, Gram-stain negative, non-spore-forming and psychrotolerant bacterium, designated strain XJ109T, was isolated from a sewage water sample collected from Xinjiang Uigur Autonomous Region, China. Phylogenetic analysis based on 16S rRNA gene sequence indicated that strain XJ109Trepresents a novel member of the familyFlavobacteriaceae. The strain showed 95.5 % similarity with the 16S rRNA gene sequence ofEmpedobacter brevisLMG 4011T, 95.4 % withChishuiella changwenliiBY4T, 95.3 % withEmpedobacter falseniiNF 993Tand 92.3 % withWeeksella virosaDSM 16922T. Strain XJ109Tshowed the common phenotypic and chemotaxonomic characteristics of the familyFlavobacteriaceae, containing menaquinone-6 (MK-6) as the predominant respiratory quinone and iso-C17:03OH and iso-C15:0as the major fatty acids. The polar lipid profile consisted of phosphatidylethanolamine, one unidentified phospholipid and two unidentified lipids. The genomic DNA G+C content was 38.0 mol%. Strain XJ109Twas positive for catalase and oxidase activities, and it was observed to grow at 4–30 °C (optimal 16–20 °C), pH 6.5–10.0 (optimal 7.0–7.5) and in media containing 0–2.0 % (w/v) NaCl (optimal 0.5 %). On the basis of the polyphasic evidence presented, strain XJ109Tis considered to represent a novel genus and species of the familyFlavobacteriaceae, for which the nameAlgoriella xinjiangensisgen. nov., sp. nov. is proposed. The type strain is XJ109T(=CGMCC 1.10229T=JCM 16590T).
