PEROXIDASE AND POLY PHENOLOXIDASE ACTIVITY IN PEAT OF VIRGIN AND RECLAMATED AREAS OF EUTROPHIC PEAT BOG ECOSYSTEM
Polyphenol oxidase and peroxidase activity was determined in virgin peat deposit (3 m) and residual eutrophic peat (1 m) under permanent grasses in microfield experiment. Enzyme activity in virgin soil was determined through the thickness (0–100 cm); in residual peat – up to 60 cm deep – at the beginning of observations (1993), and through the profile – in subsequent terms (2002 and 2008). While the ratio «polyphenol oxidase activity: peroxidase activity» was approximately equal to 1, that could point to the relational balance of the processes of synthesis and decay of humic substances – both in virgin and reclamated peat of investigated ecosystem.
Keywords: peat bog ecosystem, virgin peat, residual peat, microflora, enzymes, peroxidase, polyphenoloxidase
