WebNov 1, 2016 · This cryptic sulfur cycle was replicated in laboratory incubations using 18 O-enriched water, demonstrating that the field results do not solely result from mixing processes in the natural environment. Numerical modeling of the laboratory incubations scaled to represent the salt marsh sediments suggests that the uptake rate of sulfate … WebTheoretically, in a cryptic sulfur cycle such sulfur could be oxidized by a sulfur compound with intermediate oxidation state, the latter thereby becoming more reduced. However, unless there is an external oxidant such as O 2 that re-constitutes sulfur compounds with intermediate oxidation states, this cryptic cycle cannot be perpetuated ...
