This study investigates how heating affects organic matter bioavailability in marine sediments, finding that heating does not significantly alter bulk OM bioavailability but mobilizes older material.

This study traces the evolution of microbial alkaline phosphatases and shows their role in phosphorus recycling through geological time, highlighting their expansion during the Neoproterozoic and their association with specific metabolic strategies.

This study examines how glacier-induced upwelling affects microbial communities in Arctic marine systems, finding that it alters nutrient availability and microbial composition.

This study tests if adding labile compounds to deep ocean water stimulates microbial consumption of recalcitrant organic carbon, finding no priming effect and instead highlighting microbial competition as a key factor.

This study shows microbial exoenzymes played a key role in Earth's oxygenation by enhancing nutrient recycling and supporting cyanobacterial productivity.
