FIG. 1.

Time courses of DMS (■ and □), MT (▴ and ▵), and methane (⧫ and ◊) of slurries prepared from the sediment of a ditch from a minerotrophic peatland (De Bruuk, Nijmegen, The Netherlands) after the addition of DMS to a final concentration of 40 μM. The slurries were incubated under N₂ (solid symbols) and N₂-CO₂ (open symbols). No degradation of DMS () and no accumulation of MT (×) or methane was found in heated slurries (121°C; 20 min) amended with DMS and incubated under N₂ or N₂-CO₂. VOSC, volatile organic sulfur compounds (DMS or MT).
