Mycelial cultures of the fungi were obtained from the
inner living tissues of the fruit bodies in potato dextrose
agar (PDA; Merck) medium with benomyl. All of the
isolates were maintained in PDA slants at 4C. Basidiomycetes
mycelia were grown at 25C in submerged liquid
cultures. The liquid medium (pH 6.6) contained glucose
2%, peptone 1%, and yeast extract 2% (Hatvani, 2001).
One hundred milliliters of the medium in 250mL Erlenmeyer
flasks was inoculated by five 5-mm mycelial agar
plugs from the PDA Petri cultures. The inoculated flasks
were shaken at 150 rpm at 25C. The culture fluid was
separated from pellets by filtration after 7 days of
fermentation. The culture fluids were extracted threetimes
with 1:1 chloroform:methanol (9:1) solution. The
chloroform:methanol fraction was evaporated and the
extracted material was dissolved in DMSO (Merck).
The aqueous fraction was also stored.
All extracts and fractions from fruiting bodies and
mycelial cultures were stored at 4C until use for assaying
their activities.
