Scientists successfully engineered baker’s yeast to produce ganoderic acids, potent anti-cancer compounds from medicinal mushrooms, at much higher levels than found in farmed mushrooms. By identifying key enzymes responsible for converting simpler compounds into active ganoderic acids, researchers created yeast strains that produce these valuable compounds 100-10,000 times more efficiently than traditional mushroom farming. This breakthrough could make these expensive medicinal compounds more accessible and affordable for medical research and potential drug development.
