Microalgae Vischeria punctata Vischer, strain IPPAS H-242 (K.A. Timiryazev Institute of Physiology and Hydrology of the Russian Academy of Sciences) were cultivated in a laboratory photobioreactor; the best medium for biomass yield was Bold's medium. Addition of cyanocobalamin and thiamine to Bold's medium did not lead to an increase in biomass yield. To increase the carotenide content in the microalgae biomass, dosed exposure to various concentrations of hydrogen peroxide was used: from 0.1 to
