The capacity to produce hydrogen sulfide (H2S) via cysteine degradation is ubiquitous in the human gut microbiome
D. J. Braccia, X. Jiang, M. Pop, B. Hall
This study identifies widespread cysteine-degrading bacteria in the human gut microbiome capable of producing hydrogen sulfide, suggesting a broader role for H2S production than previously attributed to sulfate-reducing bacteria.
