Table 3.
The laccase activities of four virus-free fungal isolates after 10 days of growth on different media, that is, solid potato dextrose agar (PDA) and malt extract agar (MEA), liquid potato dextrose broth (PDB) and malt extract (ME). Laccase activity is expressed as nmol of generated DMOPox per minute per mg of mycelium dry weight. Data represent the mean of three replicates ± standard error. Letters denote statistically significant differences between values in the same column, that is, fungal isolates grown on the same medium, at p < 0.05.
