Effect of Octyl- and Nonylphenols on Growth Photosynthetic Activity and Toxins' Forming of Cyanobacteria Planktothrix Agardhii
RESUMO
The effect of octyl- and nonylphenols on growth, photosynthesis and toxin production by the bloom-forming Cyanobacteria Planktothrix agardhii was investigated. Alkylphenols were shown to inhibit growth of algae, at this inhibition rate decreases over cultivation. One of the reasons is decrease of alkylphenols concentration because of abiotic and biological processes. Growth inhibition of P. agardhii by alkylphenols is accompanied by increase of photosynthetic pigments synthesis. Considered culture P. agardhii was shown to produce several microcystins, the main of which is demethylated microcystin-RR (dm-RR). Under alkylphenols-induced stress toxins production is stimulated and concentration of extra-cellular dm-RR increases.
