When plankton samples were incubated anaerobically with a cysteine-sulfide reducing agent, pronounced methane evolution occurred. This activity was inhibited by air, CHCl3, C2H2, and 2-bromoethanesulfonic acid. Adding [14C]CO32− resulted in accumulation of [14C]CH4. Portions of the digestive tracts of three fishes were incubated in methanogenic media, and two of the samples showed the presence of methanogenic bacteria.
