Various suspended particles, zooplankton biomass, and freshly defecated fecal pellets were examined as possible sources for CH 4 production in oxygenated seawater. The results attest to the presence of methanogenic bacteria in particles and suggest that they originate from the digestive tracts of zooplankton and survive in fecal pellets. These methanogenic bacteria are able to produce CH 4 through use of competitive and noncompetitive substrates.
