During time-series observations in Sagami Bay, Japan, the concentration of dissolved dimethylsulfoniopropionate (DMSPd), a precursor of dimethylsulfide (DMS), was negatively correlated with salinity. In the laboratory, low-salinity shock reduced DMS production rates of the natural bacterial community and induced rapid DMSP release from a dinophyte,Heterocapsa triquetra, suggesting that low-salinity shock reduced DMSPdconsumption but enhanced DMSPdproduction, which agrees with the negative correlation between DMSPdand salinity observed in Sagami bay. In addition, low-salinity shock did not affect DMSP lyase activity ofH. triquetra. Low-salinity shock would increase the contribution from algae in DMS production, leading to an increase in potential DMS productivity in the environment.
