The effect of quercetin on brown hydras, endosymbiotic and free-living algae
Quercetin is the most significant flavonoid which is an antioxidant, but sometimes it also performs a prooxidative effect. Brown hydra (Hydra oligactis Pallas, 1766) is a freshwater animal belonging to the phylum Cnidaria. It was treated with quercetin (0, 2, 0, 25, 0, 3 gL−1) and compared to the control, as well as endosymbiotic algae isolated from green hydra Desmodesmus subspicatus (Chlorophyceae) (Chodat) Hegewald and Schmidt, Mychonastes homosphaera (Chlorophyceae) (Skuja) Kalina and Punčochářová and free-living related alga Chlorella vulgaris Beij. [K&H, 1992], strain SAG 211-11b. Morphological changes were observed by using a stereo microscope and included migration in the experimental dish, reactions to mechanical stimuli, secretion of mucus from hydra body and mortality. Cytological and histological changes were observed using light microscopy. At higher concentrations of toxicant quercetin caused damages of ectoderm and gastroderm of brown hydra and growth inhibition of endosymbiotic algae. Free-living alga treated with quercetin showed higher viability compared to the isolated endosymbiotic algae.
