Klappentext
A Guide to the Latest Developments in Bioprocessing that can be Applied in both the Biopharmaceutical and Biochemical Industries Bioprocessing Technology for Production of Biopharmaceuticals and Bioproducts offers a review of some current developments in bioprocessing and puts an emphasis on the effective tools and methods. With contributions from noted experts in the field, the text contains a review of six enabling technologies that cover a broad range of scientific and engineering topics. The authors include information about the history of the process and technologies used in the development of a selection of biopharmaceuticals and bioproducts. As the authors explain, the development of new processing methods and the improvement of traditional reactors and host strains has led to recent advances in manufacturing sciences. Given these new developments, the book explores the engineering methods that can be used for large-scale applications. Bioprocessing Technology for Production of Biopharmaceuticals and Bioproducts contains the information needed to better understand both the reactor technology as well as the characteristics and specific needs of the host strains. Host strains include primarily mammalian cells, and bacteria. This important guide:
