Abstract

Allelopathy in the aquatic environment can cause or facilitate the dominance of certain species of cyanobacteria and microalgae. Field studies and laboratory experiments have shown that allelopathy occurs in all marine, brackish and freshwater habitats. Furthermore, some cyanobacteria and microalgae produce harmful allelopathic compounds which can have negative effects on plants, animals and even humans. However, relatively few environmental factors have been investigated in terms of their effect on the production of allelopathic compounds. Currently, only a few studies have documented the effect of biotic and abiotic factors on the allelopathic activity of cyanobacteria and microalgae. To the most often described biotic factors affecting the production of allelopathic compounds belong: characteristic properties of donor and target species, their size and initial cell concentration, growth phase and amount or frequency of the filtrate addition. Moreover, a number of abiotic factors like light intensity, temperature and availability of nutrients may also influence production of antimicrobial agents. To better evaluate the significance of the phenomenon of allelopathy, we need to study in more detail the diversity of biotic and abiotic factors affecting production and secretion of active allelopathic compounds. Understanding the mechanisms and consequences of the impact of allelopathic cyanobacteria and microalgae in aquatic ecosystems should therefore be considered essential and fundamental for future research.
