Overview
- Jiangnan University researchers, who published their study Wednesday in Trends in Biotechnology, raised gadusol output to 4.2 grams per liter, nearly 93 times higher than before.
- They rebuilt the zebrafish gadusol pathway in E. coli and then boosted production with small RNA controls and optimized growth, targeting a UV‑protective molecule found in fish eggs and some corals.
- Early lab assays showed UV shielding and antioxidant activity on par with vitamin C, suggesting potential to both block harmful rays and mop up free radicals.
- The team created a quick screen that flags high‑producing strains when a purple reagent turns yellow as gadusol neutralizes free radicals, cutting time and cost versus chemical analyses.
- Commercial use is not imminent, with experts citing formulation, safety, scale‑up, and regulatory hurdles, and a co‑author only predicting products in about two years if those steps succeed.
