Jeff investigates an understudied route to produce the powerful global warming gas methane from microbial degradation of DMSP. DMSP is one of the Earth’s most abundant organosulfur compounds with key roles in global nutrient, sulfur cycling, signalling and climate regulation. Currently, he uses culture-dependent and -independent microbial ecology techniques, such as DNA-Stable Isotope Probing, to characterise anoxic microorganisms assimilating DMSP in diverse sediments, and those who process the DMSP catabolites DMS and MeSH into methane.
