Özet
Manganese-dependent peroxidase (MnP) production was performed in an immobilized cell bioreactor in which Phanerochaete chrysosporium BKM-F-1767 was immobilized on polystyrene foam. The immobilized cell culture yielded significantly greater MnP activity than the conventional stationary liquid culture. Cultivation was carried out in batch mode; the effect of glucose concentration was investigated and growth kinetics parameters were found as, micromax=0.59 day(-1), Ks=0.33 g/L and Kss=14.5. Batch operation led to maximum MnP (770.82 U/L) in the culture medium containing 0.05% Tween 80, 10 g/L glucose, and 174 microM Mn2+ at 37 degrees C and pH 4.5. Enzyme productivity was obtained as 110.12 U/day/L.
