Abstract
A process for the microbial production of a protein susceptible to inactivation in a fluid production medium by continuously and reversibly protecting said protein against said inactivation during the production stage, separating the protein from the production medium, deprotecting the protein, and recovering the protein product. The process is especially useful for obtaining substantially increased yields of the protein in question by continuously precipitating said protein.
