Reduction of iron and humic substances as a dominant respiratory process in arctic peat soils
Investigators from San Diego State University, Washington University, and Stanford University will collaborate to study the role of iron and humic substances as electron acceptors in anaerobic respiration in peat soils of drained thaw lake basins in the Arctic. The role of microbial physiology in ca...
