Microbial methanogenesis in the sedient and water column of the Western and Central Basins of Lake Erie was studied. Year to year methane production varies, but relative methanogenesis by geographical location is constant with near shore and harbors having highest production. The Western Basin generally supports more methane production than the Central Basin. Four species of methanogenic bacteria, Methanobacterium ruminantium, Methanobacterium strain M.q.H., Methanospirillum Hungatii, and Methanosarcina barkerii, were shown by the direct flourescent antibody technique to be distributed in specific locations in the Lake and its harbors. Laboratory study of these same methanogenic species showed that they produce an average of 1.2 umole of methane per hour per 10/8 cells. Methane accumulation does not not inhibit methane production; nydrogen depletion terminates production.
