Laccase activity in the presence and absence of cell-wall dye as a function of time. There was no significant difference in laccase activity among the stained samples and unstained control at any time interval. All samples exhibited a statistically significant (P<0.05) drop in laccase activity between the 0 and 24 h time intervals [Unstained (*), Uvitex (*), Eosin Y (**)]. Only the Unstained and Eosin Y samples retained a statistically significant reduction in laccase activity between the 0 and 48 h time intervals.
