Differences of enzymatic activity during composting and vermicomposting of sewage sludge mixed with straw pellets
Original language description
The study aims were focused on profiling eight hydrolytic enzymes by fluorescence method using a multifunctional modular reader and studying the proportion of basic microorganism groups during composting and vermicomposting of sewage sludge mixed with straw pellets in several proportions (0, 25, 50, 75, and 100%). Enzymatic activity was usually less in the presence of earthworms than in the control treatment because some processes took place in the digestive tract of the earthworm. The enzymatic activity during composting and vermicomposting of sewage sludge and their mixtures stabilized at the following values: b-D-glucosidase-50 mmol MUFG/h/g dw, acid phosphatase-200 mmol MUFP/h/g dw, arylsulphatase-10 mmol MUFS/h/g dw, lipase-1,000 mmol MUFY/h/g dw, chitinase-50 mmol MUFN/h/g dw, cellobiohydrolase-20 mmol MUFC/h/g dw, alanine aminopeptidase-50 mmol AMCA/h/g dw, and leucine aminopeptidase-50 mmol AMCL/h/g dw. At these and lesser values, these final products can be considered mature and stable.
