This research discovered how a compound called emodin from the medicinal plant Polygonum cuspidatum can dramatically increase production of an important industrial enzyme called laccase in fungi. The findings help optimize sustainable enzyme production for various applications. Impacts on everyday life: – More efficient production of enzymes used in eco-friendly paper manufacturing – Better methods for treating industrial wastewater and pollutants – Advances in developing biosensors for environmental monitoring – More sustainable industrial processes using natural compounds – Reduced costs for enzyme-based products and treatments
