A novel methylotrophic bacterium, strain Zm11^T, was isolated from reddish brown snow collected in a moor in Japan. Cells of the isolate were Gram-stain-negative, motile, and rod-shaped (0.6–0.7 × 1.2–2.7 μm). Growth was observed at 5–32 °C with an optimum growth temperature of 25–28 °C. The pH range for growth was 5.4–7.8 with an optimum pH of 6.8. The strain utilized only methanol as carbon and energy sources for aerobic growth. The major cellular fatty acids (> 40% of total) were summed feature 3 (C_16:1ω7c and/or C_16:1ω6c) and C_16: 0. The predominant quinone was Q-8, and major polar lipids were phosphatidylethanolamine and phosphatidylglycerol. The complete genome of strain Zm11^T is composed of a circular chromosome (2,800,413 bp), with G + C content of 46.4 mol%. Phylogenetic analyses were conducted based on the 16S rRNA gene sequence and conserved proteins encoded in the genome. The results of analyses indicate that strain Zm11^T is a member of the family Methylophilaceae but does not belong to any existing genus. On the basis of its genomic and phenotypic properties, strain Zm11^T (= DSM111909^T = NBRC114766^T) is proposed as the type strain of a new species in a new genus, Methyloradius palustris gen. nov., sp. nov.

从日本沼泽地收集的红棕色雪中分离出一种新型甲基营养菌菌株 Zm11 ^T。分离物的细胞为革兰氏染色阴性、运动型和杆状 (0.6–0.7 × 1.2–2.7 μm)。在 5–32 °C 下观察到生长，最佳生长温度为 25–28 °C。生长的 pH 范围为 5.4–7.8，最适 pH 为 6.8。该菌株仅利用甲醇作为有氧生长的碳源和能源。主要细胞脂肪酸（> 总量的 40%）总结为特征 3（C _16:1 ω 7 c和/或 C _16:1 ω 6 c）和 C _{16: 0}. 主要的醌是 Q-8，主要的极性脂质是磷脂酰乙醇胺和磷脂酰甘油。菌株Zm11 ^T的完整基因组由一条环状染色体（2,800,413 bp）组成，G+C含量为46.4 mol%。基于 16S rRNA 基因序列和基因组中编码的保守蛋白进行系统发育分析。分析结果表明菌株Zm11 T^是嗜甲基菌科的一员，但不属于任何现有的属。根据其基因组和表型特性，拟将菌株 Zm11 ^T (= DSM111909 ^T  = NBRC114766 ^T ) 作为新属沼泽甲基藻新种的模式菌株将军 十一月，sp。十一月
