Abstract: Both glycerol and potato wastewater are difficult-to-utilize waste from industrial processing. Thus, it is necessary to search for new economical methods of waste utilization to obtain products of higher value, decrease the production costs and protect the environment. One of the solutions to this problem might be simultaneous application of glycerol and potato wastewater as components of culture media for the production of Candida utilis fodder yeast biomass. This yeast strain is able to use glycerol from culture media as the only source of carbon, while the deproteinated potato wastewater might be the source of nitrogenous compounds and minerals. As a result, there is the possibility to obtain C. utilis fodder yeast biomass rich in such valuable nutrients as protein, fat, β-glucans, vitamins and microelements.
