Book 1992ertheless, the biogeochemical analysis of DOM isdescribed in only a few textbooks on limnology (most thoroughly byWetzel). The orgins of dissolved organic substances are largelyphotosynthetic; DOM is either autochthonously synthesized by littoraland pelagic flora through secretions and autolysis of

Extracellular enzymes in a polyhumic lake: important regulators in detritus processingssumed to undergo significant processing by microbial glycosidases and aminopeptidases. Measured enzymes are partially modified in their activity by lake water acidity, temperature and humic matter. Extracellular enzymes are regarded as important regulators in microbial detritus processing and substrate utilization.

With climatic change and environmental pollution, UV irradiance, acidification and eutrophication may increase further. In this paper impacts of UV irradiation, pH and eutrophication on the structure, properties and biodegradation of aquatic HS are discussed.
