New gram-positive bacteria were isolated from 1-year-old sludge from a wastewater treatment plant. The isolates are coccoid to rod-shaped, nonmotile aerobes that form neither spores nor mycelia. They are characterized by a peptidoglycan with directly cross-linked meso-diaminopimelic acid (type A1 gamma), by the presence of menaquinone MK-8(H4), and by the lack of mycolic acids. The strains have complex fatty acid patterns with i-C16:0 and straight-chain saturated and unsaturated fatty acids as major components. The G + C content of the DNA is 70 mol%. The results of chemotaxonomic studies and a 16S ribosomal DNA sequence comparison support our proposal to assign these bacteria to a new genus, the genus Janibacter gen. nov.; the type species is Janibacter limosus sp. nov., and the type strain of J. limosus is strain HKI 83 (= DSM 11140).
从一家污水处理厂的1年陈污泥中分离出了新型革兰氏阳性菌。这些分离菌呈球状至杆状，为不运动的需氧菌，既不形成孢子也不形成菌丝体。它们的特征在于具有直接交联的内消旋二氨基庚二酸的肽聚糖（A1γ型）、存在甲基萘醌MK-8(H4)以及缺乏分枝菌酸。这些菌株具有复杂的脂肪酸模式，以异-C16:0以及直链饱和与不饱和脂肪酸作为主要成分。DNA的G + C含量为70摩尔%。化学分类学研究结果和16S核糖体DNA序列比较支持我们将这些细菌归为一个新属即詹氏菌属（Janibacter gen. nov.）的提议；模式种是泥栖詹氏菌（Janibacter limosus sp. nov.），泥栖詹氏菌的模式菌株是HKI 83菌株（= DSM 11140）。
