Název v původním jazyce

Effects of different oxygen saturation to activity of complex biomass and aqueous crude extract of cyanobacteria during embryonal development in carp (Cyprinus carpio L.)

Popis výsledku v původním jazyce

This study evaluates effects of different oxygen concentration to toxicity of complex cyanobacterial biomass and aqueous extract of two cyanobacterial samples (prepared with regard to content of the most studied cyanobacterial toxin microcystin: biomass1 with content of microcystins 2560?g ? l-1 of dry weight and biomass 2 with content of microcystins 70?g ? l-1 of dry weight, i.e. almost 37-times lower concentration) during embryonal development of carp (Cyprinus carpio). Effects of complex biomass and aqueous extract were tested at concentrations 120, 80 and 40 mg ? l-1 in four replicates, two of them aerated and two without aeration. The studied endpoints included beginning and end of embryo hatching, the presence of eye points at 48 h after fertilization, filling of air bladder, cumulative mortality and glutathion-S-transferase (GST) activities in surviving embryos. There was significant increase in mortality in all variants without aeration after exposure to cyanobacterial biomas
