Extracts of acetate‐grown Methanosarcina barkeri strain Fusaro formed methane from acetate plus ATP and form acetyl phosphate under H 2 . Coenzyme A (CoA) is stimulatory. Inhibitors of methanogenesis are cyanide, propyliodide and bromoethanesulfonic acid. In cofactor‐free extracts methanogenic activity from acetate was restored by addition of ATP, CoA, coenzyme M and 7‐mercaptoheptanoylthreonine phosphate. An enzyme‐bound corrinoid was found to be involved in methanogenesis from acetate.
