摘要
The anaerobic digestion process has been one of the key processes for renewable energy recovery from organic waste streams for over a century.The anaerobic digestion microbiome is,through the continuous development of novel techniques,evolving from a black box to a well-defined consortium,but we are not there yet.In this perspective,I provide my view on the current status and challenges of the anaerobic digestion microbiome,as well as the opportunities and solutions to exploit it.I consider identification and fingerprinting of the anaerobic digestion microbiome as complementary tools to monitor the anaerobic digestion microbiome.However,data availability,method-inherent biases and correct taxa identification hamper the accuracy and reproducibility of anaerobic digestion microbiome characterization.Standardisation of microbiome research in anaerobic digestion and other engineered systems will be essential in the coming decades,for which I proposed some targeted solutions.These will bring anaerobic digestion from a single-purpose energy-recovery technology to a versatile process for integrated resource recovery.It is my opinion that the exploitation of the microbiome will be a driver of innovation,and that it has a key role to play in the bio-based economy of the decades to come.
