Abstract
The cell walls are removed from two distinct auxotropic mutant strains of yeast. The protoplasts thus obtained are fused and the cell walls regenerated. The strains obtained are cultured on a medium where the original auxotrophs cannot develop and the hybrid or recombinant strains are recovered. The strains obtained by the process are useful for preparing yeast proteins.
