Contribution of fungal macromolecules to soil carbon sequestration

Abstract

Fungal products have long been implicated as important contributors to soil carbon-sequestration. However, there is surprisingly little information on hyphal biochemistry and the patterns of decomposition. We examined the temporal sequence of decomposition in Fusarium avenaceum, a widespread soil fungus. The sequence of decomposition showed a 74% reduction of fungal tissue. As the atmospheric concentration of C02 continues to increase beyond critical levels from the burning of fossil fuels, and with the effects of climate change already being seen, carbon sequestration is a necessary remediation measure.
