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.
