Diversity of micro-fungi associated with aerobic composting process of organic wastes

Abstract

Organic waste is gradually degraded during composting process, producing carbon dioxide, water, heat, and humus, the relatively stable end product. The degradation process is carried out by living organisms, of which fungi appear to have the most important role since they break down tough debris (cellulose, lignin, and other resistant materials), enabling other microorganisms to continue the decomposition process. In Binh Duong province, municipal organic wastes, recently, being treated by aerobic composting process at industrial scale. In order to properly control the biological composting process and maximize its efficiency, the understanding of involved microorganisms is essential. Therefore, the objective of this study was to isolate and identify the fungi associated with large scale municipal biosolid waste composting process in Vietnam.
