A newly described strain of the genus Methanosarcina was isolated from submarine canyon sediments and is shown by comparative sequence analyses of 16S ribosomal DNA and the gene encoding methyl coenzyme M reductase, mcrI, to be a strain of Methanosarcina siciliae. Morphological and physiological characteristics are described. In contrast to the two previously described strains that grow exclusively on methanol, methylamines, and dimethylsulfide, M. siciliae C2J is also capable of growth on and methanogenesis from acetate. We propose that the species description for M. siciliae be amended to include aceticlastic strains.
从海底峡谷沉积物中分离出一种新描述的甲烷八叠球菌属菌株，通过对16S核糖体DNA和编码甲基辅酶M还原酶的基因mcrI进行比较序列分析，表明它是西西里甲烷八叠球菌的一个菌株。描述了其形态和生理特征。与之前描述的仅能在甲醇、甲胺和二甲基硫醚上生长的两种菌株不同，西西里甲烷八叠球菌C2J也能够利用乙酸盐生长并进行产甲烷作用。我们建议修订西西里甲烷八叠球菌的物种描述，以包括能利用乙酸盐的菌株。
