Biological decomposition of organic matter
WebComposting is a biological degradation of organic matter usually containing various polymeric organic compounds such as lignin and cellulose. It is a dynamic process that includes the enzymatic breakdown of these polymers into soluble organic carbon and sugars which are suitable for utilization by microorganisms ( Gou, Wang, Zhang, Lou, & … WebDissolved organic matter (DOM) is found in every water body, both marine and freshwater. It is a heterogeneous mixture derived primarily from the decomposition products of plant material, bacteria and algae. The character of aquatic DOM varies according to precursor material, which falls broadly into two categories: allochthonous, which is ...

WebApr 14, 2024 · The efficient reactivity and mobility of dissolved organic matter (DOM) affect biogeochemical processes. As important components that link aboveground and belowground vertical systems under the binary 3D structure of karst, fissures provide soil–water–nutrient leakage channels and storage spaces. However, … Biodegradation is the breakdown of organic matter by microorganisms, such as bacteria and fungi. It is generally assumed to be a natural process, which differentiates it from composting. Composting is a human-driven process in which biodegradation occurs under a specific set of circumstances. The process of biodegradation is threefold: first an object undergoes biodeteri…
