Due to the high level of diversity in the microbial flora and the intensive temporal changes in temperature, pH and moisture content, aerated composting represents a more complex microbial community than many other microbial ecosystems. Conventional and current methods have limited success in tracking its temporal changes of bacterial population driven by aerobic metabolism. We believe that nanoscale science and engineering, especially the proposed, DNA-based nanobarcode system may provide an exciting and novel opportunity to overcome the difficulties of tracking microbial population dynamics.
