Abstract

Microbial life consumes oxygen when organic matter is degraded, causing many environments to reach low oxygen concentrations that exclude most animal life. For example, in the oceans, deoxygenation has been linked to large economic losses in marine fisheries. This project follows up on the recent discovery that biochemical processes that consume oxygen have two rate-limiting steps, and that the degradation of some…
