Researchers found a fungus that produces a helpful enzyme called laccase that can break down certain agricultural wastes. They discovered that a fungus called Pycnoporus sp. made the most laccase and then found the best conditions for it to work well, like having low carbon and specific nutrients. By adjusting factors like glucose amount and pH, they made the fungus produce laccase faster and better. Under these optimal conditions, they got the highest laccase activity in just 7 days, compared to the usual 16 days, totaling 225 units per liter. They also learned that acidic conditions are best for laccase's function. Finally, the fungus successfully broke down various agricultural wastes, with rice bran being the most effective at producing useful sugars.
