节杆菌属

丰度和多样性最高的是革兰氏阳性菌群，其中节杆菌属（Arthrobacter）为天山冻土中的优势细菌类群。

The most abundant and diverse isolates were members of Gram-positive bacteria , particularly the genus Arthrobacter as a dominant group in culturable populations .

用亚硝化培养基从底泥中分离了NH4-N降解优势菌20株，经鉴定，分别为Bacillus、节杆菌属（Arthrobacter）、Pseudomonas、Xanthomonas、Nitrosococcus和Nitrobacter等6个属。

And 20 strains of dominant bacteria have been separated from bottom mud with nitrosation , and identified as 6 classes , such as : Bacillus , Arthrobacter , Pseudomonas , Xanthomonas , Nitrosococcus and Nitrobacter .

对这些菌株进行了初步分类鉴定，它们属于假单胞菌属、黄单胞菌属、节杆菌属、葡萄球菌属、棒杆菌属、黄杆菌属、气球菌属和利斯特氏菌属。

These strains were identified as eight genera , they are Pseudomonas , Xanthomonas , Arthrobacter , Staphylococcus , Corynebacterium , Flavobacterium , Rhizobium , Aerococcus , and Listeria .
