Summary:In the past years, a series of initiatives on biotechnology research have been launched, which were focused on investigating methods to improve productivity and metabolic processes related to biomass production, as well as for bio-refining biomass to produce biofuels or other valuable products from the food and pharmaceutical sectors. Advanced techniques of the biological systems electromagnetic stimulation with radiation from various frequency domains are increasingly being studied and applied in practice. This paper analyses the physiological response of the algal species of Chlorella sorokiniana exposed to the DC and AC electric fields generated at low frequencies in the range of 10 Hz - 10 kHz and for the different electric field intensities. Through a series of algal suspension exposures in the electric field of well-defined parameters, the cell growth rate for the exposed samples was analysed, as compared to the samples unexposed in the electric field. The experimental results were interpreted in terms of cellular mechanisms identified on theoretical studies and can be applied in the perspective of the development of more efficient biotechnological processes.
