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 study uses SIP-enabled multi-omics to analyze soil microbiome responses to drought and rehydration, showing increased anabolic processes and shifts in metabolomes.

This paper shows how obligate symbiosis in rove beetles arises from irreversible chemical and behavioral changes that force dependence on host ants.

This study shows that sulfur redox intermediates sustain microbial activity in sulfate-limited methane seep sediments by driving sulfur transformations and anaerobic methane oxidation.

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 paper compares Raman and NanoSIMS for measuring 2H incorporation in E. coli cells, showing they yield comparable results with specific mass ratios offering different advantages.
