a
Data are means ± standard deviations of three independent experiments.
b
Reported data are for maximal values of decolorization or laccase activity, and numbers in parentheses indicate the time (days) required to attain those values.
c
The initial A520/A350 ratio was 0.460 ± 0.04.
d
Mycelial growth is given as g of dry weight per liter of culture broth after 15 days of fermentation.
e
ND, no detectable activity.
