Enhancement of human serum albumin production in Saccharomyces cerevisiae

Experiments were accomplished to reduce the extent of proteolysis by simply controlling the culture conditions instead of the gene manipulation techniques. L-arginine and L-lysine were chosen as a protease inhibitor analogue With the assumption that they might act as the potential inhibitors against proteases involved in the rHSA proteolysis. The addition of arginine and lysine resulted in a considerable positive effect on the secreted rHSA production level.
