The inventions relate to biotechnology, and more particularly to a process and equipment for cultivating and producing a biomass from microalgae, primarily plankton. The essence of the group of inventions consists in that 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, and 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 culture mixture is illuminated cyclically, wherein the pH value of the culture mixture is maintained in a range of 8.5-9.5 throughout all of the cycles by adding a solution containing lactic acid bacteria to the culture mixture at the beginning of each light cycle, said solution having a pH value selected in a range of 3.5-4.0 and being added in an amount of 1-3 ml per litre of culture mixture. The group of inventions makes it possible to produce a finished product in 48 hours, 1 litre of which contains from 7 to 10 grams of raw microalgal mass.
