Editorial: Meta-omic approaches to the complex anaerobic communities in wastewater treatment plants and digesters

Abstract

Anaerobic digestion is an established process for the stabilization of organic matter and production of renewable energy that has a central role in sustainable development and circular economy. It is currently being used worldwide for fuel generation and the production of a stabilized fertilizer from livestock manures and crop residues. High-rate anaerobic technologies can be applied to treat wastewater from virtually any industrial process, and novel strategies open avenues for obtaining products of biotechnological interest, including alternative energy carriers, such as methane and hydrogen, and valuable end-products with industrial application, such as organic acids.
