Abstract:
:The present investigation showed by means of autoradiography that the cyanobacterium Microcystis wesenbergii did not incorporate [H]thymidine at nanomolar concentrations, whereas its associated heterotrophic bacteria appearing in the gelatinous cover of the cyanobacterium became labeled. Several other tested cyaobacteria and algae did not incorporate [H]thymidine.
