Process Analytical Technology (PAT) for Continuous Purification of mRNA via Precipitation and Tangential Flow Filtration

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Continuous downstream processing of messenger ribonucleic acid (mRNA) therapeutics requires purification strategies that are scalable, robust, and capable of removing product‐ and process‐related impurities from in vitro transcription mixtures.

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

Enabling Bioprocess Upscaling Prediction Through Hybrid Modelling and Transfer Learning Under Small‐Data Scenarios

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Accurate prediction of bioprocess scale‐up is critical for accelerating the deployment of novel and sustainable biomanufacturing systems. However, this remains challenging as multi‐scale data is expensive to generate and mechanistic understanding is often incomplete, leading upscaling decisions to rely heavily on empirical expertise.

Scale‐Down Platforms for Process‐Oriented Enzyme Screening Using Microfluidics

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Enzyme screening platforms are typically evaluated based on their throughput and analytical performance rather than their ability to mimic the conditions encountered at large scale. In bioreactors, enzymes experience gradients in substrate concentration, oxygen availability, pH, temperature, and interfacial exposure, caused by imperfect mixing

GlycoMAC: A Multiscale Metabolic‐Glycosylation Framework for Predicting Glycosylation Across Conditions in Mammalian Cell Cultures

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Antibody productivity and glycosylation quality in CHO cell cultures emerge from a dynamically evolving metabolic environment, yet existing models often work in isolation or at a single scale. Here, we present a multiscale mechanistic framework linking molecular, cellular, and macroscopic scales to predict how inputs shape bioprocess ...

Mechanistic Digital Model for Real‐Time Monitoring and Optimization of Adenovirus Production

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Adenoviral vectors are a critical vaccine platform, with billions of vaccine doses administered during the COVID‐19 pandemic. In addition, they are promising therapeutics for cancer treatment. To advance their manufacturing, real‐time monitoring of adenovirus production is essential for process optimization, yield improvement, and product ...

Isolation and Characterization of Random Citrate Synthase Variants That Increase Acetate Generation by Escherichia coli

Biotechnology and Bioengineering, EarlyView.
ABSTRACT A method to select Escherichia coli citrate synthase variants having reduced activity was developed based initially on the increased generation of acid, observed visually by prolonged color change in the pH indicator bromocresol purple. Five hundred fifty‐two potential variants were isolated and each were cultured on glucose as sole carbon ...
