Microbial Hydrolysates as Amino Acid Source in Cell Culture Media for Cellular Agriculture

Biotechnology and Bioengineering, EarlyView.
ABSTRACT The high cost of cultivation media remains one of the barriers to the commercialization of cultivated meat. Current serum‐free media reduce reliance on fetal bovine serum but only achieve modest cost savings. Especially at larger scales (> 20 m3), pharmaceutical‐grade amino acids and recombinant proteins remain major cost drivers.

LLM‐Guided Parameter Optimization for Mechanistic CHO Cell Bioreactor Models

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Mechanistic models of Chinese Hamster Ovary (CHO) cell cultures are essential for efficient bioprocess development and control, yet parameter estimation remains a critical challenge in model calibration. As model complexity increases, the number of parameters grows and their values become highly system‐specific due to biological variability ...

High Cell Density Cultivation of HEK293 Cells Using a 2L Membrane‐Stirred Bioreactor

Biotechnology and Bioengineering, EarlyView.
ABSTRACT The use of perfusion systems for the continuous cultivation of animal cells at high cell density (HCD) for the production of recombinant proteins, viruses, and viral vectors has many advantages. Besides an enhancement of volumetric productivity and high cell viability, the product quality can be improved through a steady‐state environment ...

Status and future of recombinant adeno‐associated virus vector manufacturing

Biotechnology Progress, EarlyView.
Abstract Sixty years of adeno‐associated virus (AAV) research illustrates a trajectory marked by basic science exploration, iterative innovation, persistent challenges, a number of clinical setbacks, as well as commercial therapeutic triumphs. This continual evolution has led to recombinant AAV (rAAV) becoming a cornerstone of modern gene therapy ...

Advanced glucose control strategies leveraging Raman spectroscopy for optimized mammalian cell culture manufacturing

Biotechnology Progress, EarlyView.
Abstract Maintaining consistent quality in the manufacturing of biotherapeutic proteins in mammalian cell culture is challenging, with unplanned deviations causing inconsistencies and potential batch failure. Current methods for monitoring and controlling critical process parameters (CPPs) rely on slow, labor‐intensive offline analyses.

Application of commercial ultrafiltration membranes for protein purification by high performance countercurrent membrane purification (HPCMP)

Biotechnology Progress, EarlyView.
Abstract High performance countercurrent membrane purification (HPCMP) has emerged as a promising diffusive separation strategy for the purification of recombinant proteins and monoclonal antibodies (mAbs). However, prior studies employed dialysis membranes, which are designed for diffusive separations but have not been validated for biopharmaceutical ...

Screening of bispecific antibodies during single cell cloning of recombinant Chinese hamster ovary cell lines to improve titer and product quality

Biotechnology Progress, EarlyView.
Abstract Development of therapeutic bispecific antibodies (BsAbs) poses significant manufacturability challenges associated with correct chain pairing and an increased diversity of impurities. Here we address this with a product quality assessment during cell line development (CLD), forgoing the need for genetic characterization during cell line ...

Regenerative perfusion bioreactor for biologics production with lower COGs

Biotechnology Progress, EarlyView.
Abstract Perfusion bioreactor systems enable intensified bioprocessing with high cell densities and volumetric productivities in monoclonal antibody (mAb) manufacturing. However, their widespread adoption remains constrained by the high consumption of chemically defined cell culture media.
