2.3. Culture conditions
C. gallica KJ412304 was cultured in semi-solid-state fermentation
conditions in 250-mL cotton-plugged Erlenmeyer flasks containing
5.0 g of sawdust. The substrate was hydrated with 15 mL of
minimum medium (MM) adjusted by 25 mM acetate buffer (pH
5.0). This MM contained (g L1): glucose, 5; casein peptone, 6;
KH2PO4, 0.025; MgSO4$7H2O, 0.25; KCl, 0.5. Inoculationwas carried
out directly in the Erlenmeyer flasks. Six plugs (diameter, 3 mm),
from a 5-day growing fungus on malt extract agar (MEA) plates, per
Erlenmeyer were used as inoculum. The cultures were supplemented
with CuSO4 as laccase-inducer (solution sterilized separately,
60 mM) at the beginning of the cultivation. The Erlenmeyer
flasks were incubated statically for 12 days under an air atmosphere
at 30 C and 90% humidity, to avoid evaporation, in complete
darkness.
