Photo-organotrophic acetate utilization in a stratified eutrophic lake Dr. Oláh, J. — Biebl, H. — Overbeck, J. Bio-stratification and the parameters of the kinetics of acetate utilization have been studied in the stratified, eutrophic Kolksee (Schleswig-Holstein, German Federal Republic) using the method of Wright and Hobbie. The physico-chemical character of the lake corresponded to conditions common to stratified, eutrophic lakes and reflected the anaerobic conditions of the hypolimnion. The simultaneous occurrence in the lake of red water in the metalimnion and of green water in the hypolimnion is the result of the mass occurrence of photosynthetic bacteria. No report on this unusual pigment stratification has been published in the relevant literature. The intense photo-organotrophic utilization of acetate in the metalimnion has not been observed earlier and the phenomenon may be regarded as a new factor in the organics household of waters. The kinetic parameters of dark acetate consumption are the maximum natural substrate concentration (Kt + Sn) : 80 fig liter" 1, the theoretical maximum uptake (V max, heterotrophic potential) : 400 fig litre" 1, hr — 1 the regeneration time of the substrate (Tt) : 0.2 hours.
