Pinnacle Food Group Limited Completes First Bench-Scale Fermentation of Recombinant Human Lactoferrin (rhLF) Using Methanol-Free Pichia Fermentation
The bench-scale results inform strain optimization and process development as the company evaluates potential scale-up.
Sentiment and the balance of points
Rhea-AI Sentiment reads the wording of the document, how positive or negative its language is on a 1 to 5 scale. The balance of points shown with the takes weighs what the document actually discloses, so the two can disagree, for example when a trial that missed its main goal is described in upbeat language.
Rhea-AI Summary
Pinnacle Food Group (PFAI) completed its first bench-scale fermentation of recombinant human lactoferrin through its wholly owned subsidiary Pinnacle Food AgTech HK.
The first-generation yeast strain was tested in a 5-liter fermenter, and laboratory analyses confirmed production of recombinant human lactoferrin, or rhLF. The process used methanol-free Pichia fermentation technology developed under a research collaboration with Bioboost Synbio Consulting. This was the strain's first evaluation under controlled bench-scale conditions, following its creation announced in April 2026. The results inform strain optimization and process development and support evaluation of potential scale-up.

VANCOUVER, BC AND HONG KONG, HK / ACCESS Newswire / October 13, 2026 / Pinnacle Food Group Limited (NASDAQ:PFAI) ("Pinnacle Food" or the "Company"), a technology-driven company operating at the intersection of smart farming and bioengineering, today announced that its wholly owned subsidiary, Pinnacle Food AgTech HK Limited ("PFHK"), has successfully completed the first bench-scale fermentation of the Company's first-generation recombinant human lactoferrin ("rhLF") yeast strain in a 5-liter bench-scale fermenter.
Laboratory analyses, including high-performance liquid chromatography (HPLC), sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and Immuno Blotting, confirmed rhLF expression. The fermentation was conducted using the methanol-free Pichia fermentation technology developed under the Company's research collaboration with Bioboost Synbio Consulting Inc. ("Bioboost"). This methanol-free approach is designed to offer a cleaner, safer and more cost-effective alternative to conventional methanol-based fermentation approaches.
The milestone builds on the Company's April 2026 announcement of the creation of its first-generation rhLF yeast strain and marks the first evaluation of that strain under controlled bench-scale fermentation conditions. The results further inform strain optimization and process development, and support the Company's evaluation of potential scale-up.
"Completing our first bench-scale fermentation and confirming rhLF expression is an important step for our biotech program," said Jiulong You, Chief Executive Officer of Pinnacle Food Group Limited. "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."
Lactoferrin is an iron-binding glycoprotein naturally present in milk, including human milk, and is used as an ingredient in infant nutrition, dietary supplements and other nutritional applications. Recombinant human lactoferrin (rhLF) that is produced through precision fermentation is intended to be structurally similar to the lactoferrin found in human milk.
