OPTIMIZATION OF FERMENTATION CONDITIONS IN THE BIOPHARMACEUTICAL PROCESS
ABSTRACT
This paper explores the influence of fermentation conditions on the yield and quality of biopharmaceutical, and analyzes the mechanism of key factors such as temperature, pH and oxygen supply in the fermentation process. The study pointed out that the appropriate temperature not only promotes the growth and me tabolism of microorganisms, but also significantly increases the yield of biopharmaceutical; and the regulation of pH value has an important impact on the microbial enzyme activity and cell membrane permeability, and then affects the yield. At the same time, the adequacy of oxygen supply is directly related to the growth and product synthesis of aerobic microorganisms. In addition, medium composition, fermentation time and stirring speed were also found to be key factors affecting the quality of biopharmaceuticals. Through the experimental design, this paper systematically analyzes the experimental results under different fermentation conditions, and proposes targeted optimization strategies, aiming to provide theoretical basis and technical support for improving the yield and quality of the biopharmaceutical, and further promote the development of the biopharmaceutical industry.
