Influence of Zn2+ and Oxygen Supply on Malic Acid Production and Growth of Aspergillus oryzae

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Malic acid is a valuable platform chemical traditionally derived from fossil‐based resources. Microbial cultivation with Aspergillus oryzae offers a sustainable alternative based on renewable feedstocks. In this study, a well‐established minimal medium for malic acid production, commonly used in previous research to ensure reproducibility, was

Development of Raman Spectroscopy and Machine Learning Methods for Protein Aggregate Quantification: Application to BSA in Chromatographic Processes

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Protein aggregation poses a significant risk to biopharmaceutical product quality, as even minor amounts of oligomeric species can compromise efficacy and safety. Rapid and reliable detection of protein aggregates thus remains a major challenge in biopharmaceutical manufacturing.

High Yield Branched Puromycin Linker Design Enables Efficient cDNA Display and Chemical Modification of Peptides

open access: yesBiotechnology and Bioengineering, EarlyView.
A novel puromycin linker for cDNA display was synthesized via SPAAC reaction. Its functionality was confirmed by recovering intact DNA after selection against EpCAM. The system also enabled the verification of bicyclic peptides during display, demonstrating its utility for constructing and screening structurally complex peptide libraries.

Quantitative Analysis Reveals Hitchhiking Drives Polysorbate Hydrolase Persistence Via Host Cell Protein–Antibody Interactions

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Polysorbate‐degrading host cell proteins (HCPs) represent a critical challenge in the manufacturing of monoclonal antibody therapeutics due to their potential to persist during downstream processing. While their enzymatic activity has been characterized, the role of direct HCP‐mAb interactions, particularly those involving polysorbate ...

Introducing PBL into Civil and Structural Engineering

open access: yes, 2015
The benefits of problem based learning for students are a deeper understanding of lecture material, and the development of problem solving and collaboration skills which will greatly enhance their educational experience. This approach has been successful in other programmes as it departs from the traditional ‘what I am told I need to know’ to ‘what I ...

Multimodal Chromatography in the Downstream Processing of mAb‐Based Products: Mechanisms, Strategies, and Applications

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Multimodal chromatography has emerged as a powerful tool for the purification of monoclonal antibodies (mAbs) and their derivatives—including antibody fragments (Fabs), Fc‐fusions, bispecific (BsAb), and antibody–drug conjugates (ADCs)—offering enhanced selectivity through the integration of ionic, hydrophobic, hydrogen‐bonding, and π–π ...

Mediated Electrochemical Probing and Machine Learning for Cysteine and Reduced Monoclonal Antibody Quantification

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Biopharmaceutical manufacturing requires robust analytics and process controls throughout production to insure high yield of quality products. New methodologies for rapidly accessing and integrating data‐rich information from complex dynamic biological environments are of great interest.

Hidden O‐Deglycosylation Activity Triggers O → C Rearrangement for Aryl Di‐C‐Glucoside Formation by the C‐Glycosyltransferase From Fortunella crassifolia

open access: yesBiotechnology and Bioengineering, EarlyView.
Here, we uncovered an unexpected O‐deglycosylation activity of the C glycosyltransferase (FcCGT), forming phloretin (1) from phloretin 2'‐O‐glucoside (2). In the presence of UDP, FcCGT catalyzes the O→C rearrangement to yield nothofagin (3). Upon additional UDP‐glucose, further C‐glycosylation occurs, forming phloretin 3',5'‐di‐C‐glucoside (4 ...

RBD‐SD1 Nanoparticle Vaccines From DPP4‐Using Merbecoviruses Elicit a Cross‐Reactive Antibody Response but Limited Cross‐Protective Immunity

open access: yesBiotechnology and Bioengineering, EarlyView.
SpyCatcher‐mi3 nanoparticles displaying RBD‐SD1 from MERS‐CoV, NL140422, and HKU4 elicited robust and cross‐reactive IgG responses in mice. Only MERS‐CoV RBD‐SD1 induced neutralizing antibodies against MERS‐CoV and protected human DPP4 mice from a MERS‐CoV challenge, indicating conserved serologic but limited cross‐neutralizing epitopes.
