General description

Dimethyl trisulfide (DMTS), a volatile sulfur compound (VSC), is a major aroma consituent in cooked Brassicaceous vegetables. Dimethyl trisulfide formation is reported during beer aging. It has been reported to be responsible for common malodour from fungating cancer samples. It is an important taste and odor (T&O)-causing compound in China, mainly associated with the septic/swampy odor. It has been identified as a common odor-producing compound by Microcystis (on its decay). Granular activated carbon (GAC) adsorption of dimethyl trisulfide, an algal odorant, has been reported.

The vibrational theory of olfaction assumes that electron transfer occurs across odorants at the active sites of odorant receptors (ORs), serving as a sensitive measure of odorant vibrational frequencies, ultimately leading to olfactory perception. A previous study reported that human

The effects of methanethiol (MT) on biological sulfide oxidation were studied in a continuously operated bioreactor, in which chemolithoautotrophic bacteria belonging to the genus Thioalkalivibrio convert hydrogen sulfide (H2S) at natron-alkaline conditions. Previous bioreactor experiments have shown that always a
