A PROCESS FOR CULTURING OF RECOMBINATED YEAST CONTAINING A DNA OF PRESURFACE ANTIGEN AND SURFACE ANTIGEN IN HEPATITIS TYPE B VIRUS

摘要

In case that enzyme maternal cell including preS2-S Ag protein gene controlled by glyceroaldehyde-3-phosphoric dehydration enzyme(GAP) promoter is cultivated, recombinant yeast is produced by supplying and cultivating excess substrate to keep the concentration of ethanol over a certain standard since when the concentration of dextrose is 0. Therefore, the above cultivation method of recombinant yeast can improve the productivity of entire surface and surface antigen.
