Summary
This study uses thermodynamics of irreversible processes and microcalorimetry to precisely describe how protein synthesis efficiency depends on process conditions. Understanding these relationships is key to optimizing industrial protein production.
Area of Science:
- Biochemical Engineering
- Chemical Thermodynamics
