The influence of light intensity on the production of the gas dimethylsulfide (DMS) by Skeletonema costatum was studied in batch cultures. Culture pairs were grown under identical conditions except for light intensity. Cultures displayed a spike of dissolved DMS following inoculation and an increase in dissolved DMS during log phase and stationary phase. These increases were slower and less pronounced under reduced illumination. DMS production per cell declined throughout log phase under reduced light, but remained constant throughout log phase under full illumination. The total mass of DMS produced under reduced light was less than half that produced under full illumination.
