Online automatic tuning and control for fed-batch cultivation [PDF]
Bioprocess and Biosystems Engineering, 2007 Performance of controllers applied in biotechnological production is often below expectation. Online automatic tuning has the capability to improve control performance by adjusting control parameters. This work presents automatic tuning approaches for model reference specific growth rate control during fed-batch cultivation.

Repetitive Fed-Batch: A Promising Process Mode for Biomanufacturing With E. coli
Frontiers in Bioengineering and Biotechnology, 2020 Recombinant protein production with Escherichia coli is usually carried out in fed-batch mode in industry. As set-up and cleaning of equipment are time- and cost-intensive, it would be economically and environmentally favorable to reduce the number of ...

High cell density cultivation of E. coli in shake flasks for the production of recombinant proteins
Biotechnology Reports, 2022 Batch cultivation of recombinant bacteria in shake flasks typically results in low cell density due to nutrient depletion. Previous studies on high cell density cultivation in shake flasks have relied mainly on controlled release mechanisms.
