Formation Of Methylmercaptan And Dimethylsulfide From Methoxylated Aromatic Compounds In Anoxic Marine And Fresh Water Sediments, Kai Finster, Gary M. King, Friedhelm Bak

Anaerobic formation of dimethylsulfide (DMS) and methylmercaptan (MSH) in anoxic sulfide-containing slurries from marine and fresh water sediments was stimulated by addition of syringate (4-hydroxy,3,5,-dimethoxybenzoate) and 3,4,5,-trimethoxybenzoate. The release of DMS and MSH occurred during the consumption of the aromatic monomers and ceased after their depletion. DMS was the dominant methylated sulfur compound in fresh water sediments, in contrast to marine sediments where MSH was predominant. No production of volatile organic sulfur compounds was observed in slurries containing gallate (3,4,5,-trihydroxybenzoate) or in autoclaved controled. About 50-65% of the methoxy carbon could be accounted for by peak accumulation of DMS and …

Abstract Anaerobic formation of dimethylsulfide (DMS) and methylmercaptan (MSH) in anoxic sulfide‐containing slurries from marine and fresh water sediments was stimulated by addition of syringate (4‐hydroxy,3,5,‐dimethoxybenzoate) and 3,4,5,‐trimethoxybenzoate. The release of DMS and MSH occurred during the consumption of the aromatic monomers and ceased after their depletion. DMS was the dominant methylated sulfur compound in fresh water sediments, in contrast to marine sediments where MSH was predominant.
