Sulfur is both crucial to life and a potential threat to health. While colonic sulfur metabolism
mediated by eukaryotic cells is relatively well studied, much less is known about sulfur …

In this review, we focus on the activities transpiring in the anaerobic segment of the sulfur
cycle occurring in the gut environment where hydrogen sulfide is produced. While sulfate …

Sulfur is a vital element that all living things require, being a component of proteins and
other bio-organic substances. The various kinds and varieties of microbes in nature allow for …

Sulfur metabolism and sulfur-containing metabolites play an important role in the human
digestive system, and sulfur compounds and pathways are associated with inflammatory …

Hydrogen sulfide (H 2 S) is present in the lumen of the human large intestine at millimolar
concentrations. However, the concentration of free (unbound) sulfide is in the micromolar …

Among bacterial metabolites, hydrogen sulfide (H2S) has received increasing attention. The
epithelial cells of the large intestine are exposed to two sources of H2S. The main one is the …

Background Recent evidence implicates microbial sulfidogenesis as a potential trigger of
colorectal cancer (CRC), highlighting the need for comprehensive knowledge of sulfur …

Sulfate is present in foods, beverages, and drinking water. Its reduction and concentration in
the gut depend on the intestinal microbiome activity, especially sulfate-reducing bacteria …

There is increasing evidence that hydrogen sulfide (H2S), produced by intestinal sulfate-
reducing bacteria (SRB), may be involved in the etiopathogenesis of chronic diseases such …

Hydrogen sulfide (H2S) is a toxic gas that has been recognized as an important mediator of
many physiological processes, such as neurodegeneration, regulation of inflammation …
