Abstract/OtherAbstract:
We have studied the dynamics of cylindrospermopsin concentration (CYN) of a benthic cyanobacterium of the genus Oscillatoria under various light conditions over the different growth phases. The present study is the first one reporting on the effect of abiotic factors on the CYN accumulation and release by a benthic species. In particular we have measured the concentrations of both intracellular and extracellular CYN. We found that the total CYN content is highest during the exponential growth phase at intermediate light level (10 μE m(-2) s(-1)) and during the stationary growth phase at more extreme lower and higher light levels. Our results also indicate that the amount of the extracellular form varied between 56 % and 96 % of the total CYN concentrations. We found no relationship between CYN content and growth rates. These results suggest many similarities with planktonic species but also highlight some differences.
