This volume represents the proceedings of the "Workshop on the measurement of microbial activities in the carbon cycle of freshwaters", held in Plön, Germany, in August 1977. The 18 papers in this volume were divided in the following groups: O2-consumption, Heterotrophic CO2-fixation, Uptake kinetics of labelled organic substrates and others.
