Coupled methyl groups in dimethyl sulphide
Low field methyl tunnelling spectra of dimethyl sulphide have been measured using field cycling NMR and indicate the existence of two distinct methyl groups with tunnel. frequencies of 100kHz and 750kHz. Spectra show a significant broadening of the Larmor peak at those fields at which the Larmor and tunnel frequencies are equal. These are resonances between the rotational and spin dynamics of t...
متن کاملHigh olfactory sensitivity for dimethyl sulphide in harbour seals.
Productive areas are patchily distributed at sea and represent important feeding grounds for many marine organisms. Although pinnipeds are known to travel on direct routes and return regularly to particular feeding sites, the environmental information seals use to perform this navigation is as yet unknown. As atmospheric dimethyl sulphide (DMS) has been demonstrated to be a reliable indicator f...
متن کاملPenguins are attracted to dimethyl sulphide at sea.
Breeding Spheniscus penguins are central place foragers that feed primarily on schooling pelagic fish. They are visual hunters, but it is unclear how they locate prey patches on a coarse scale. Many petrels and storm petrels (Procellariiformes), the penguins' closest relatives, use olfactory cues to locate prey concentrations at sea, but this has not been demonstrated for penguins. Procellariif...
متن کاملDimethyl sulphide degradation using immobilized Thiobacillus thioparus in a biotrickling filter.
Gaseous dimethyl sulphide (DMS) was eliminated in a biotrickling filter with Thiobacillus thioparus grown in polyurethane foam cubes as carrier material. The temperature, pH and empty bed residence time of the gas were maintained at 30 degrees C, 7.0 and 40 s, respectively. In the first 45 days, DMS loads of around 2.0 gDMS m(-3) h(-1) were fed to the BTF to adapt T. thioparus to DMS consumptio...
متن کاملTreatment of waste gas containing low concentration of dimethyl sulphide in a high performance biotrickling filter.
A bench-scale biotrickling filter was operated in the laboratory for the treatment of dimethyl sulphide (DMS). The biotrickling filter was packed with pre-sterilized polyurethane foam and seeded with biomass developed from garden soil enriched with DMS. The biotrickling filter was operated for the generation of process parameters. The biotrickling filter could remove an average removal efficien...
