The effect of sterilisation on poly(ethylene glycol) used as the enzyme activity stimulator in the Phanerochaete chrysosporium culture

摘要

The physical behaviour of poly(ethylene glycol)s, stimulators of enzyme production in the Phanerochaete chrysosporium shaken culture, was studied. Polymers were partly degraded during sterilisation. In spite of that, lignin peroxidase activity decreased by less than 15%, since the degradation products retain some stimulating ability. (C) 2003 Elsevier Science Ltd. All rights reserved.
