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 uses isotopic analysis of volatile fatty acids to show that inhibiting methanogenesis in ruminants alters microbial fermentation pathways, reducing energy-generating processes.

This paper investigates carbon isotope fractionations in bacterial fermentation products and shows they can serve as isotopic signatures for studying fermentation in both modern and ancient environments.

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

This study investigates the clumped isotope signatures of different methanogenic pathways and identifies factors influencing methane isotope compositions.
