Distribution of methionine content in the protein subfractions of polymet DNA hybrid and parent strain CB89 was determined in dependence of glucose concentration and aeration intensity. The increase in synthesized methionine appeared in fractions 1+2 and residue. Technofunctional properties of parent strains and hybrids were compared for whole cells and cell wall (residue). Results demonstrate that enrichment in methionine in the cell wall fraction resulted improvement of emulsifying ability. Bioavailability of methionine content was better in DNA hybrid yeast than in parent strain and was the best when propagated in whey medium.
