The effect of anthracene on total dry matter and extracellular enzyme analysis of a starch-amended composting process

<p>Composting technology has been widely used as a cost-effective, eco-friendly, and efficient solid waste management option for the bioremediation of organic pollutants. Most studies have focused on the use of compost in the bioremediation of organic pollutants, without any attention being paid to the effect of the organic pollutants on the composting process. Therefore, in this study, the effect of an organic pollutant (anthracene) on a starch-amended composting process is reported. In order to determine the effect, the total dry matter and the extracellular enzyme analysis (EEA) of starch-specific (α-glucosidase) and -nonspecific (β-glucosidase) substrates were monitored. Over the course of the experiments, there appeared to be some form of anthracene effect on the progression in the total dry matter and the extracellular enzyme analysis (EEA) of the α-glucosidase, particularly in the starch and anthracene–amended composts. The interactions between the starch and the anthracene consistently increased the total dry matter and the α-glucosidase activity of the starch and anthracene–amended composts. This observation is novel, and the kind of interaction is yet unknown. Therefore, detailed investigation to understand the magnitude of such interaction is necessary to potentially resolve these issues.</p>
