An experimental study of the process of growing microalgae of the Chlorella vulgaris BIN strain in an experimental photobioreactor on various nutrient media with identical lighting and temperature parameters was carried out. The basis for the manufacture of nutrient media were formulations diluted in distilled water, Guillard F/2 and Tamiya, widely used in the cultivation of fertilizers and recycled agricultural effluents, as a cheap alternative medium. When processing the experimental data obtained by regression analysis methods, a calculation formula was obtained that determines the number of cells of the Chlorella vulgaris BIN strain formed during cultivation, taking into account a given range of temperature and illumination parameters of the suspension, values of the hydrogen index, concentrations of chemical compounds of iron, phosphates and potassium, affecting the cultivation of microalgae in suspension. The experimental and calculated data presented in the article can be used as part of measures related to optimizing the operating cycles of modern photobioreactors.
Keywords:chlorella, Chlorella vulgaris BIN strain, microalgae, nutrient medium, cultivation, photobioreactor
