Abstract: The invention relates to a process and equipment for cultivating and producing a biomass from microalgae, primarily plankton. A microalgal biomass is cultivated in a single bioreactor chamber in the shape of a vertically oriented parallelepiped. The culture mixture is illuminated by artificial light sources mounted on the inner side of one of the broad walls of the bioreactor chamber in horizontal rows throughout the height of the bioreactor chamber. The culture mixture is illuminated cyclically. Spray heads are mounted on the inner side of the opposite wall of the bioreactor chamber so that 4 spray heads are arranged symmetrically around each artificial light source. The pH value of the culture mixture is maintained in a range of 8.5-9.5 by the addition thereto of a lactic acid bacteria-containing solution at the beginning of each light cycle in an amount of 1-3 ml per litre of culture mixture, said solution having a pH value selected in a range of 4.0-5.0.

Abstract: The invention relates to biotechnology. The plankton strain of the unicellular green alga Chlorella vulgaris GKO, which has a thin cell wall, deposited in the Russian National Collection of Industrial Microorganisms under the registration number of VKPM A1-24. The strain VKPM A1-24 of the unicellular green alga Chlorella vulgaris can be used to produce food biomass intended for preparation of a beverage, concentrate, paste or dry powder. The invention makes it possible to shorten the period of cultivation of the biomass of unicellular algae.
