This study investigates pH-dependent flocculation in Komagataella phaffii. We found it peaks at pH 4.0 and is reversible. Flo5-1 critically affects this process, and Nrg1 negatively regulates it. Our findings offer vital insights for optimizing bioprocesses using this yeast host.
Carnivorous Nepenthes and Sarracenia pitcher fluids hydrolyze PET and PBAT polyesters. Nepenthesin, an aspartic proteinase, is a key enzyme, showing comparable activity to known cutinases. This study highlights carnivorous plants as a novel source for efficient polyester degrading enzymes in plastic recycling.
Flo8 knockout in Komagataella phaffii prevents pseudohyphal growth and reduces adherence. This study reveals it significantly elevates glucose-regulatable promoter activity, boosting recombinant protein yields up to 7-fold. This new host strain offers higher productivity per gene copy and improved process robustness for methanol-free bioproduction.Original Publication

Researchers have found inexpensive, food-grade alternatives to expensive serum albumins in cell culture media, potentially cutting costs for cultivated meat production and biopharmaceuticals by up to 73%. This breakthrough addresses a major bottleneck, making sustainable protein and affordable medicines more accessible.
A meta-analysis reveals the core genetic blueprint and dynamic gene regulation of CHO cell factories.
This podcast details the engineering of transmembrane alkane monooxygenases (AlkB) to improve Tulipalin A synthesis. The research focuses on enhancing the hydroxylation of isoprenyl acetate, a crucial step for this polymer precursor. Through rational design and site-directed mutagenesis, AlkB variants with significantly improved activity were developed, while maintaining selectivity. The engineered enzyme is part of a novel biocatalytic cascade, representing a significant step towards sustainable production of Tulipalin A and expanding bio-based chemicals.
Dive deep into the complex world of Adeno-Associated Virus (AAV) purification for gene therapy. Our expert guest explains the challenges of separating perfect therapeutic AAVs from a myriad of impurities and discusses the cutting-edge downstream processing techniques—from ultracentrifugation to advanced chromatography—that are making these revolutionary treatments safer, more effective, and accessible.
Discover how scientists harnessed a unique bacterial lipase, SpL, featuring a novel catalytic tetrad and dual access tunnels, to achieve highly efficient synthesis of pharmaceutical-relevant amides directly in water. This breakthrough bypasses traditional wasteful methods, offering a greener, faster route for chemical manufacturing.
This interview explores the systematic immobilization of L-lactate oxidase on various porous carriers, revealing that hydrophilic agarose supports with amine groups yield the highest activity. Key discussion points include the unexpected efficiency and stability achieved through simple adsorption versus covalent binding, and the crucial role of ionic interactions governing the enzyme's attachment to different functionalized surfaces.
