Summary

Story summary

Researchers at Jiangnan University used CRISPR to engineer Fusarium venenatum to produce protein more efficiently than traditional livestock.
The modification reduces glucose use by 44% and increases protein yield by about 2.24 times versus the wild strain.
The study in Trends in Biotechnology highlights environmental benefits, including lower greenhouse gas emissions and reduced land use.
Challenges remain, including energy-intensive fermentation and plant-based protein competition, limiting scalability to meet rising demand.
