The method of combining white rot fungal strains was used to enhance laccase activity,and the interaction mechanism between strains was also studied.The laccase activity of combined fungi of strain 55(Trametes trogii) and strain m-6(Trametes versicolor) were 24.13 and 4.07-fold higher than that of strain 55 and strain m-6,respectively.No inhibitory effect was observed when the two strains were co-cultivated.On plate cultivation,there was hyphal interference in the contact area,where laccase activity was the...
