A team at Jiangnan University in Wuxi, China, has engineered a fungus that tastes like meat, digests easier, and requires a fraction of the resources to grow. Using CRISPR gene-editing, they modified Fusarium venenatum—a fungus already used in mycoprotein—by removing just two genes. The result, called FCPD, produces the same nutritional punch with dramatically lower environmental cost.
The problem they were solving is straightforward: we need protein, and conventional animal farming is expensive. Raising livestock generates roughly 14% of global greenhouse gas emissions and devours land and freshwater at unsustainable rates. As the world population heads toward 9.8 billion by 2050, the pressure to find alternatives is only intensifying.
Fusarium venenatum already had promise—it naturally develops a meat-like texture and flavor—but it had two flaws. Its thick cell walls made it harder for humans to digest, and its production was resource-intensive. The Jiangnan team used CRISPR to delete a gene responsible for chitin synthase, thinning the cell walls and making the protein inside more bioavailable. They also removed a gene for pyruvate decarboxylase, which rewired the fungus's metabolism to run on 44% less sugar while growing 88% faster.

Computer modeling showed that FCPD production emits up to 60% less greenhouse gas over its full lifecycle compared to the original strain. Growing this fungus-based meat requires 70% less land than raising chickens in China. It could cut freshwater pollution risk by 78%.
"A lot of people thought growing mycoprotein was more sustainable, but no one had really considered how to reduce the environmental impact of the entire production process," said Xiaohui Wu, the study's first author. That gap—between "this is better" and "how much better can we actually make it"—is where the real innovation lives.
The work, published in Trends in Biotechnology in November, doesn't claim to be a silver bullet. But it does something more useful: it shows that gene-editing tools can be used not just to create new foods, but to make the production of those foods genuinely sustainable. If this scales beyond the lab, it could reshape how we think about feeding a growing world without farming it to exhaustion.
