Growth rate optimization

Definition

Growth rate optimization refers to the process of enhancing the rate at which biological organisms, such as bacteria or yeast, reproduce and develop. This concept is crucial for maximizing the efficiency of bioprocesses, particularly in industrial applications, where increased growth rates can lead to higher yields of desired products. By utilizing systems biology and metabolic modeling, researchers can identify and manipulate specific pathways to improve growth conditions and overall productivity.
