Researchers developed a new method to produce laccase, a useful enzyme with many industrial applications, by growing oyster mushrooms on prairie plants and waste materials from bio-oil production. Through optimization experiments and economic modeling, they found that this process could produce laccase at prices significantly lower than current commercial enzyme products, making it economically viable at small to moderate production scales. The method has the added benefit of providing farmers with a financial incentive to grow perennial prairie plants instead of traditional crops, supporting ecological and soil health improvements.
