Sulfate reduction and methanogenesis in the sediment of a saltmarsh on the east coast of the United Kingdom.

Abstract

Methane formation from CO2, but not from acetate, was detected within the same horizon of sediment where sulfate reduction was most active. Sulfate reduction was 3 orders of magnitude greater than annual methanogenesis. The 2 processes were not separated either spatially or temporally, but occurred within the same layer of sediment at the same time of the year. -from Selected Water Resources Abstracts
