Abstract
Yeast cells whose DNA has been appropriately engineered to produce and to secrete lysozyme under control of a regulatable promoter are grown in the substantial absence of lysozyme synthesis and then are induced to produce and to secrete lysozyme under growth-limited conditions. This process is particularly suitable for the production of human lysozyme or mutants thereof.
