Discriminating approach of various microplanktonic‐stage contributions to whole electron transport system (ETS) measurements in sea‐water sampless. b. Bacateria Data obtained from cultures of natural bacterial populations were applied to various water samples in order to determine both the phytoplanktonic and bacterial contributions to whole ETS water‐sample measurements. The bacterial part was estimated both by cell enumerations and HPLC muramic‐acid measurements and the phytoplankton contribution by enumeration and chlorophyll levels. An appropriate first‐order equation is adequate to low carbon content samples but must be corrested for highly organic loaded samples in order to obtain a better adjustment between the sum of the “estimated” phytoplanktonic and bacterial ETS and the really‐measured ETS concentrations in the water samples.
