“…Strain M1 grew under anoxygenic phototrophic conditions using DMS as electron donor, producing dimethyl sulfoxide (DMSO) . In strain OP-3, DMS supported both anaerobic phototrophic growth and aerobic chemolithotrophic growth in the dark (Kelly et al 1994). Strain M11 oxidized DMS only under oxic conditions, but DMSO could not be detected as an oxidation product (Jonkers et al 1998b).…”

This is the first report describing the complete oxidation of dimethyl sulfide (DMS) to sulfate by an anoxygenic, phototrophic purple sulfur bacterium. Complete DMS oxidation was observed in cultures of Thiocapsa roseopersicina M11 incubated under oxic/light conditions, resulting in a yield of 30.1 mg protein mmol(-1). No oxidation of DMS occurred under anoxic/light conditions. Chloroform, methyl butyl ether, and 3-amino-1,2,4-triazole, which are specific inhibitors of aerobic DMS oxidation in thiobacilli and hyphomicrobia, did not affect DMS oxidation in strain M11. This could be due to limited transport of the inhibitors through the cell membrane. The growth yield on sulfide as sole electron donor was 22.2 mg protein mmol(-1) under anoxic/light conditions. Since aerobic respiration of sulfide would have resulted in yields lower than 22 mg protein mmol(-1), the higher yield on DMS under oxic/light conditions suggests that the methyl groups of DMS have served as an additional carbon source or as an electron donor in addition to the sulfide moiety. The kinetic parameters V(max) and K(m) for DMS oxidation under oxic/light conditions were 12.4 +/- 1.3 nmol (mg protein)(-1) min(-1) and 2 &mgr;M, respectively. T. roseopersicina M11 also produced DMS by cleavage of dimethylsulfoniopropionate (DMSP). Specific DMSP cleavage rates increased with increasing initial substrate concentrations, suggesting that DMSP lyase was only partly induced at lower initial DMSP concentrations. A comparison of T. roseopersicina strains revealed that only strain M11 was able to oxidize DMS and cleave DMSP. Both strain M11 and strain 5811 accumulated DMSP intracellularly during growth, while strain 1711 showed neither of these characteristics. Phylogenetic comparison based on 16S rRNA gene sequence revealed a similarity of 99.0% between strain M11 and strain 5811, and 97.6% between strain M11 and strain 1711. DMS and DMSP utilization thus appear to be strain-specific.

“…There are some reports of anoxygenic phototrophic bacteria able to oxidize DMS photo-or chemo-trophically to DMSO (Zeyer et al, 1987;Visscher and van Gemerden, 1991;Hanlon et al, 1994;Kelly et al, 1994;Horinouchi et al, 1999). Most of the DMS-oxidizing phototrophs described are tolerant to high concentrations of sulphide, indicating that these bacteria can reduce DMS emission rates in sulphidic environments (Vogt et al, 1997).…”

Dimethylsulphide (DMS) is a trace sulphur gas found in most atmospheric and surface water samples, which is derived from dimethylsulphonioproprionate (DMSP). Although it has been extensively studied over the last 50 years, its natural production, consumption and cycling are still not completely understood. Until recently, DMS was believed to originate mainly from marine waters, but later studies have shown that estuaries and lakes are also an important source of DMS. DMS also originates from terrestrial plants such as maize, wheat and lichen, but it is not fully understood why. DMS is believed to have an important impact on the global environment by influencing factors such as the acidity of the atmosphere, cloud condensation nuclei (CNN) and solar insolation. The impact that humans have on the cycling of DMS and on its environmental impact is not well understood either. DMS is affected by temporal and geographical factors, as well as physical factors such as salinity and wind speed, yet when studied under El Niño conditions which modify these physical factors in vivo, there was found to be no fluctuation in the concentration of DMS in the water column. This review outlines our current state of knowledge on DMS.

“…The organic sulphur compound dimethyl sulphide (DMS) enters the atmosphere in amounts of 19-51 Tg (10l2 g) annually (Kelly et al, 1994). It has been suggested that DMS plays an important role in the global sulphur cycle (Lovelock et al, 1972) and in marine climate control (Charlson et al, 1987).…”

Dimethyl sulphoxide reduction with reduced sulphur compounds as electron donors by anoxygenic phototrophic bacteria

et al. 1997

View full text Add to dashboard Cite

The marine purple non-sulphur bacterium Rhodowulum euryhalinum strain DSM 4868 reduced dimethyl sulphoxide (DMSO) to dimethyl sulphide (DMS) chemotrophically with sulphide as electron donor. The oxidation of sulphide was correlated with the formation of polysulphides. R. euryhalinum reduced DMSO phototrophically with sulphide as well, but the amount of DMSO reduced in relation to sulphide oxidized was lower. The marine green sulphur bacterium Chlorobium wibrioforme strain DSM 8327 reduced DMSO to DMS phototrophically with sulphide and thiosulphate as electron donors. The extent of DMSO reduction was much less in the dark. Eight strains of purple sulphur bacteria -marine, brackish water and freshwater isolates -and another marine green sulphur bacterium showed a very weak capacity for DMSO reduction with sulphide or thiosulphate as electron donors in the light and dark, respectively.
