Scientists have engineered a groundbreaking strain of fungus that could transform the future of sustainable protein. Using CRISPR gene-editing tools, researchers have redesigned Fusarium venenatum—already known for its meat-like texture and flavour—into a far more productive, nutritious, and environmentally friendly food source.
The achievement, reported in Trends in Biotechnology, comes as the world searches for credible alternatives to carbon-intensive animal agriculture, which contributes roughly 14% of global greenhouse gas emissions.

The team, led by Xiao Liu of Jiangnan University, targeted two genes for removal. One gene, responsible for producing chitin synthase, was deleted to create thinner fungal cell walls. This subtle structural shift makes the fungal protein easier for the human body to digest, improving nutrient absorption.
A second deletion—removing the pyruvate decarboxylase gene—refined the fungus’s metabolic machinery. The resulting strain, named FCPD, can now generate protein 88% faster while using 44% less sugar than the original organism.
When taken beyond the laboratory and produced at a commercial scale, the advantages became even clearer. FCPD left a smaller environmental footprint regardless of where it was manufactured, cutting life-cycle greenhouse gas emissions by up to 60% compared to conventional fungal protein. Against chicken farming in China, the benefits are even starker: the gene-edited myoprotein uses 70% less land and reduces the risk of freshwater pollution by 78%.
For the researchers, these gains underscore a larger point: gene-edited foods like FCPD could help feed a growing global population without the heavy ecological toll of traditional farming. Their work hints at a new era in sustainable food technology—one where precision genetics helps shape a cleaner, faster, and more resilient global protein supply.
