BIOLOGICAL FACTORS OF WATER QUALITY IN A MESOTROPHIC ECOSYSTEM
Rubrics: ECOLOGY
Abstract and keywords
Abstract (English):
Dissolved organic matter (DOM) is one of the important parameters of water quality in aquatic ecosystems. In the experiments, phyto- and bacterioplankton actively consumed 14C-labeled chlorella hydrolyzate. Removal (by filtration) of cyanobacteria from the aquatic environment leads to an increase in the rate of DOM consumption by bacteria. This indicates the possibility of a negative effect of cyanobacterial metabolites on the physiological processes of bacterioplankton.

Keywords:
water quality, phytoplankton, algae, bacteria, 14C-chlorella hydrolyzate, heterotrophic activity, cyanobacteria, dissolved organic matter, DOM
