Short summary
Short summary
Studies on how microbes use C in soils typically assume oxic conditions but often overlook anaerobic processes and extracellular metabolite release. We examined how O2 and Fe content affect C mineralisation in forest soils by tracking 13C flow into biomass, CO2, metabolites, and active microbes under oxic and anoxic conditions. Results showed that anoxic conditions preserved C longer, especially in high-Fe soils. We conclude that microbial exudates play a role in anoxic C stabilisation.

Short summary
Short summary
We spectroscopically evaluated the gradients of dissolved C, N, S, Fe and Mn in a newly formed redox-stratified lake. The lake features an intermediate redox state between nitrogenous and euxinic conditions that encompasses vigorous open sulfur cycling fuelled by the reducible Fe and Mn stocks of the anoxic sediments. This results in substantial bottom water loads of dissolved iron and sulfate. Observations made in this ecosystem have relevance for deep-time paleoceanographic reconstructions.

Short summary
Microbial production is a key parameter in estimation of organic matter cycling in environmental systems, and fungi play a major role as decomposers. In order to improve investigation of fungal production and turnover times in environmental studies, we determined the isotopic signals encoded into lipid biomarkers of fungal pure cultures growing on various carbon substrates in media with isotopically labeled water and bicarbonate.
