摘要
The abundance and activity of methanogenic bacteria in bottom sediments of Rybinskoe reservoir were studied. The intensity of methanogenesis depended on the bottom-ground type and the season; the daily CH, production varied within a wide range of values from 0.01 to 1362 mu l CH4/(1 day). Methanogenesis was usually more intense in gray silts and less intense in sandy sediments. Of all the radioactive precursors tested, bicarbonate and acetate provided the highest rates of methanogenesis.
