In situ product recovery

Definition

In situ product recovery refers to the process of extracting a desired product directly from a biological or chemical reaction environment without the need for extensive separation or purification steps. This approach enhances efficiency by minimizing the time and cost associated with downstream processing, thereby facilitating metabolic engineering and biotechnology applications.
