Chlorella growth stimulation depending on the duration of extremely high frequencies electromagnetic radiation exposure

The result indicates the possibility of creating methods to stimulate growth rate microalgae by extremely high frequency electromagnetic radiation (EHF EMF). Pollution quarry waste water with inorganic nitrogen compounds (ammonium, nitrate, nitrite) is an important problem in mining industry. Biological treatment use plant organisms and microorganisms show efficiency require less financial labour costs than physical chemical treatment. Not all are applicable Far North conditions. Chlorella shows ability reduce nitrate ammonium concentrations wastewater, some species can survive at temperatures 3⁰C. A number works indicate stimulating effect EHF EMR on toxicity pollutants. Therefore, from under influence relevant for development. aim study was investigate duration exposure microalgae. Materials Methods: In this work, 2 control 9 working experiments were carried out cultivate vulgaris 24 hours time EMF 5 480 minutes beginning cultivation. increase biomass concentration relative values studied spectrophotometrically. Results: maximum observed 120 minutes.
