The 16S ribosomal RNAs from 10 species of methanogenic bacteria have been characterized in terms of the oligonucleotides produced by T(1) RNase digestion. Comparative analysis of these data reveals the methanogens to constitute a distinct phylogenetic group containing two major divisions. These organisms appear to be only distantly related to typical bacteria.
已根据核糖核酸酶T1消化产生的寡核苷酸对10种产甲烷细菌的16S核糖体RNA进行了表征。对这些数据的比较分析表明，产甲烷菌构成了一个独特的系统发育群体，包含两个主要分支。这些生物似乎与典型细菌的关系非常疏远。
