Pinnacle Food Group Limited (NASDAQ: PFAI) has achieved a significant milestone with its subsidiary, Pinnacle Food AgTech HK Limited, successfully completing the first bench-scale fermentation of its first-generation recombinant human lactoferrin yeast strain.
The fermentation process utilized a 5-liter bench-scale fermenter and was confirmed through laboratory analyses such as high-performance liquid chromatography, sodium dodecyl sulfate-polyacrylamide gel electrophoresis, and Immuno Blotting.
This process employed a methanol-free Pichia fermentation technology, developed in collaboration with Bioboost Synbio Consulting Inc., offering a cleaner, safer, and more cost-effective alternative to traditional methods.
The achievement follows the company's earlier announcement in April 2026 regarding the creation of the yeast strain, marking the first evaluation under controlled conditions and providing insights for strain optimization and potential scale-up.
Jiulong You, Chief Executive Officer of Pinnacle Food Group Limited, commented, "Completing our first bench-scale fermentation and confirming rhLF expression is an important step for our biotech program. This result gives our team a solid foundation for the next phase of work as we evaluate the path toward scale-up. We remain focused on building our precision fermentation capabilities to support the development of high-value biological ingredients for potential industry partners."
