Coriolus versicolor fungus from the collection of the Department of Industrial Microbiology,
Faculty of Agriculture, University of Belgrade (Serbia) was used. A culture was grown on malt
agar for 7 days. Subsequently, 10-mm diameter discs were cut with a No. 5 cork borer and the
discs were transferred into nutrient medium in order to prepare inoculums for the seeding of the
bioreactor. The normal nutrient medium for fungal growth contained 4.0 % glucose, 0.15 %
peptone (HiMedia, India), 0.15 % KH2PO4, and 0.15 % MgSO4·7H2O (Yang et al., 2012). The
fungi was cultivated in 500-mL Erlenmeyer flasks, working volume of 100 mL, at 25 ºC on a model SI 600R incubated shaker (JEIO TECH, Korea) at 135 rpm (Yang et al., 2012). After five
days, the obtained pellets were ground under sterile conditions using a laboratory blender. The
biomass was isolated by centrifugation at 5000 g for ten minutes, washed several times with
distilled water, and used as inocula for seeding of the bioreactor.
