Scale-Up Processes

The scale-up process involves expanding a microbial process from the laboratory to an industrial scale, preserving the product quality and yield.

At the laboratory scale, typically using up to 2 liters of culture, researchers select and optimize microbial strains, growth media, temperature, pH, and aeration to maximize productivity.

The process is then tested at the pilot scale, using mid-sized fermenters ranging from 10 to 1,000 liters.

This step helps identify issues not apparent at the laboratory scale, such as nutrient imbalance, heat buildup, oxygen gradients, or excessive foaming.

To address these issues, nutrient feeding rates, cooling strategies, stirring mechanisms, and airflow speeds are optimized.

Once the process performs reliably at the pilot scale, it can be transitioned to the industrial scale.

This involves fermenter volumes above 10,000 liters to manufacture large quantities of the microbial product.
