Model‐Driven Monitoring and Parameter‐Based Development of an Escherichia coli Fed‐Batch Process for Production of a Fab Antibody Fragment Across Scales

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Maintaining consistent cellular physiology during bioprocess scale‐up or scale‐down is key to developing robust processes. However, the reliability of scale‐down bioreactor systems remains debated. Although the calibration of physiological parameters in mechanistic models across scales has been proposed as a scale‐down strategy, few studies ...

Induction and Enhancement of Bacteriocin Production (Review)

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Conventionally, bacteriocins are produced by microorganisms on complex substrates, released as semi‐purified preparations or crude fermentates. These bacteriocin‐containing products often exhibit unsatisfactory purity, low active‐substance content, and high production costs, limiting their commercialization and use. This review aims to analyze

Induction Temperature and Feeding Profile Shape the Partitioning Between Soluble Product and Inclusion Body Formation in Escherichia coli

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Inclusion body (IB) processes yielding the recombinant product only as IBs are long‐established in the biopharmaceutical industry. Yet, for recombinant proteins that accumulate both IBs and soluble fraction depending on the selected upstream processing (USP) strategy, the influence of process parameters on the partitioning between both forms ...

Protein–Anthocyanin Interactions in Food Systems: A Reaction‐Network Perspective on Equilibria, Kinetics, and Degradation Pathways

ChemFoodChem, EarlyView.
Protein–anthocyanin interactions are reinterpreted beyond binding affinity through a reaction‐network perspective. Distinct protein classes modulate anthocyanin behavior through equilibrium shifts, matrix‐driven protection, self‐assembly, or covalent conjugation.
