Short summary
Our research explores microbial sulfur cycling in the 13 500-year-old sediment record of a sulfate-rich alpine lake. We present evidence for active sulfur cycling across sediment layers, even in sulfate-depleted zones, driven by uncultivated microorganisms. In addition, rapid organic matter sulfurization could contribute to its preservation. These findings enhance our understanding of the role of sulfur in organic matter preservation and deep biosphere processes.
