Abstract As an approach for assessing the dynamics of bacterial population in seawater, the survival of five isolated marine bacteria strains was assessed by the disappearance of radioactivity in the cold trichloroacetic acid (TCA)-insoluble fraction from a previously3H-labeled culture. Metabolic activity during survival experiments was assessed by the measurement of electron transport system (ETS) activity. Fractionated filtration was used to assess the grazing mortality. The particulate fraction that passed 2.0 μm and was retained in 0.2 μm was the main cause of mortality.
