Abstract
SummaryMicrobial biotechnology is essential for the development of circular economy in wastewater treatment by integrating energy production and resource recovery into the production of clean water. A comprehensive knowledge about identity, physiology, ecology, and population dynamics of process‐critical microorganisms will improve process stability, reduce CO2 footprints, optimize recovery and bioenergy production, and help finding new approaches and solutions. Examples of research needs and perspectives are provided, demonstrating the great importance of microbial biotechnology.
Highlights
Wastewater treatment is becoming part of the circular sustainability movement by integrating energy production and resource recovery into the production of clean water
Many digesters suffer from low gas yield, low stability, foaming events and other operational problems that are likely closely connected to the microbial communities (Ganidi et al, 2009), so a better understanding is needed to carry out informed control or manipulations of the digester communities
As it is not thousands of different abundant species, it is feasible to establish the knowledge needed in the near future of these few hundred relevant species
