Influence of organic pollutants on the growth of dinophytic microalgae

The results of experiments with dinophytic algae Prorocentrum cordatum are summarized. The algae growth stimulation as well as the reduction of phenol toxic effect in the culture medium with the added mussel hydrolyzate was observed. These effects were obtained at hydrolyzate concentrations from 0.05 to 0.5 mg∙l-1 in recalculation of protein and phenol concentrations up to 10 mg∙l-1. One of the reasons for P. cordatum growth stimulation in darkness and light intensity from 17 μE m-2 s-1 to 100 μE∙m-2∙s-1 is myxotrophy. It was found that phenol in a concentration from 0.25 to 10 mg∙l-1 stimulates the growth of dinophytic algae.
