Bioenergetics of microbiologically mediated water rock interactions

Microbiologically mediated sulfate reduction and methanogenesis is closely linked to the in-situ energy available for the processes, to what extent this is the case for the suboxic processes modified is not well described, but pursued here. The processes may occur when a threshold energy level is superseded. There are different threshold values for different processes and different systems, and the factors controlling this are to be studied.
