What is the related major of biopharmaceuticals?

The latest can be said to be bioengineering, followed by biotechnology (I majored in this major). The latter focuses on theory, while the former focuses on practice. Other related majors are microbiology (because the current biopharmaceutical technology mainly uses cultivating microorganisms to obtain their metabolites, that is, antibiotics and other drugs); Fermentation engineering (this major involves brewing, dairy industry, etc. ). The above are probably majors at the undergraduate level. There are many directions for graduate students, but most of them are related to pharmacy in microbiology and biochemistry.
