ABSTRACT:
Proteins contained in microbial cells, for example, cells of petroleum-assimilable yeast, are separated and purified by extracting proteins from microbial cells, treating the resulting extract solution with a cation exchanger, treating said cation exchanger containing the adsorbed proteins with a volatile basic substance in the presence of water thereby to desorb or elute the adsorbed proteins, removing said basic substance dissolved in the resulting eluate by evaporation, and then concentrating the eluate thereby to obtain the dissolved proteins.
