Electron-microscopic studies using thin sections revealed that methane-producing bacteria were an ultrastructurally diverse group. Fine structure and morphological characteristics separated these bacteria into four discrete cell types. Methanogenic bacteria displayed a gram-positive cell wall that varied considerably among different cell types. Differences in granular inclusions, reserve materials, and intracytoplasmic membranes were observed. Unique ultrastructural features were not shared by all methanogenic species studies.
使用薄切片的电子显微镜研究表明，产甲烷细菌是一个超微结构多样的群体。精细结构和形态特征将这些细菌分为四种不同的细胞类型。产甲烷细菌呈现出革兰氏阳性细胞壁，在不同细胞类型之间差异很大。观察到颗粒内含物、储备物质和胞内膜的差异。并非所有研究的产甲烷物种都具有独特的超微结构特征。
