This study uses 13C-MFA to analyze co-metabolism in Eubacterium limosum, finding that glucose cofeeding reduces flux through the Wood-Ljungdahl pathway and that cysteine provides gluconeogenic carbon.

This paper engineers Escherichia coli to produce or consume hydrogen sulfide in specific gut regions, demonstrating methods to increase and decrease H2S levels in mice.

This paper develops a transcriptional biosensor in E. coli to measure hydrogen sulfide (H2S) under both aerobic and anaerobic conditions, with a detection range of 50-750 μM.
