Abstract

Nine acetotrophic and three methylotrophic strains of methane-producing bacteria were screened for the presence of plasmid DNA. Plasmids were detected in three marine isolates, including Methanosarcina acetivorans. All three plasmids appeared to be similar based on size and restriction site analyses. The plasmid from M. acetivorans, designated pC2A, was approximately 5.1 kilobase pairs in size and was estimated to be present in a low copy number of six plasmids per genome. Multimers were also observed. A restriction map was constructed. The function of this plasmid is cryptic.
