This paper relates to studies regarding the influence of cultivation’s substrates (carbon source - molasses, glucose, methanol, malt extract, nitrogen source yeast extract, phosphorus source monobasic and dibasic phosphates), inoculum (inoculation rate and inoculum age - CFU / ml), bioprocess parameters (temperature, aeration, rate of stirring) on the development of wine and / or brewing yeast biomass. Biomasses of brewing and / or wine yeast obtained (active and inactive) have been proven to be a rich source of protein (SCP) and mono-oligosaccharides (MOS) in different feed recipes compared to other protein sources (soybean meal, corn) for animal feed. It has been demonstrated that yeast biomass obtained with use in feed recipe has beneficial effects on animal health (ruminants, pigs, horses, poultry).
