Seasonal Changes in Microbial Dissolved Organic Sulfur Transformations in Coastal Waters.
in Microorganisms
| Description | 1) First results showing that coastal marine microbes utilise carbon from DMSO for both growth and energy (assimilation and dissimilation). However, rates of DMSO dissimilation to CO2 were up to 2 orders of magnitude higher than rates of assimilation. 2) Microbial oxidation of DMSO carbon to CO2 could be a signfiicant loss process for dissolved DMSO in marine waters (new knowledge). 3) Turnover times for dissolved DMSO range between 0.6-1.9 days. |
| Exploitation Route | Adds new knowledge & experimental evidence of marine organic S cycle, specifically pathways and rates of DMSO losses. |

| Title | Application of 14C labelled DMSO |
| Description | The use of 14C labelled DMSO has been trialled and used to determine the amount of carbon from DMSO that marine microbes are utilising as either a source for growth (assimilation) or a source of energy (dissimilation). This methodology has been added to stable tracer methods to determine the sources and sinks of DMSO in seawater during a time series at a coastal long term monitoring station, L4 in the western English Channel. There is a resulting time series for 2014 and 2016. |

| Title | Stable tracer experiments for determining DMSO loss processes Station L4 |
| Description | Three stable tracers were used (13C-DMSO, d3- DMS, d6-DMSP) to determine the biological consumption, net and gross production and turnover times of DMS, DMSP and DMSO in surface waters of station L4, WCO. 2014 and 2016 datasets. |
