Evaluation of state and evolution of marine fish waste composting by enzyme activities
The feasibility of using enzyme activities for indicating the state of marine fish waste composting was examined in this study and the evolution of the composting process for a 60 day period was evaluated. Results indicated that stable and mature fish waste compost has been generated. During the composting process, oxidoreductase enzyme (dehydrogenase) and hydrolase enzyme (β-glucosidase and phosphatase) activities decreased with time since available organic compounds decreased. A good correlation among enzyme activities and different physiochemical parameters including oxygen uptake rate, carbon/nitrogen ratio, and germination index led to the conclusion that both hydrolytic and dehydrogenase enzyme activities could be feasible indicators of the state and evolution of the composting process.
