Modelling the concentration of exuded dimethylsulphoniopropionate (DMSP) in the boundary layer surrounding phytoplankton cells

Abstract

Using a steady-state diffusion model, we calculated the concentration of the ecologically relevant algal metabolite dimethylsulphoniopropionate (DMSP) in the phycosphere. Incorporating diffusive losses, the concentration was predicted to be 10 6 -fold lower than previously suggested.
