Comparison on Lignin-degrading Enzymes of Ganoderma-lucidum Fungi

The diagnostic methods of extracelluar oxidase mat were used to select lignin-degrading enzymes producers among nineteen Ganoderma lucidum fungal strains.The results showed that the producing laccase activity of G.sp.var.Tianzhi was the highest,followed by that of G.lucidum 10 and G.lucidum 8.The producing lignin peroxidase activity of G.sp.var Tianzhi was the highes,and the producing Manganese peroxidase activity of G.sp.var yuanzhi 6 and G.lucidum G 8 were the highest,followed by that of the G.sp.var.Tianzhi and G.lucidum 10.It was found that G.sp.var Tianzhi,G.sp.var.Yuanzhi 6G.lucidum 8 and G.lucidum 10 showed the highest lignin-degrading enzymes activity.
