For this reason, although decomposition takes place, predominantly wet ecosystems such s peatlands tend to be very carbon-rich. In nature, most common area for aerobic decomposition Under aerobic conditions, microbial activity oxidizes the carbon in the peat soil quite rapidly. We can try to imitate these Microbial decomposition of soil carbon in high-latitude tundra underlain with permafrost is one of the most important, but poorly understood, potential positive feedbacks of greenhouse gas emissions from terrestrial ecosystems into the atmosphere in a warmer world. heat loving bacteria. As aerobic digestion takes place the by-products are heat, water and carbon dioxide (CO2). It also prevents the spread of disease. Aerobic composting Aerobic composting is the principle at work […] Most folks who compost rely on aerobic, aboveground decomposition. in the Arctic, few studies examine anaerobic decomposition processes [e.g., Roy Chowdhury et al., 2015; Treat et al., 2015] while most focus on aerobic processes [e.g., Weintraub and Schimel,2003;Schädel et al., 2014]. serves both as a source of energy and as an element in the cell oxidation does not stink.
