| Title | Anaerobic biodegradation of phenol in wastewater treatment: achievements and limits |
| Abstract | Anaerobic biodegradation of toxic compounds found in industrial wastewater is an attractive solution allowing the recovery of
energy and resources but it is still challenging due to the low kinetics making the anaerobic process not competitive against the
aerobic one. In this review, we summarise the present state of knowledge on the anaerobic biodegradation process for phenol, a
typical target compound employed in toxicity studies on industrial wastewater treatment. The objective of this article is to provide
an overview on the microbiological and technological aspects of anaerobic phenol degradation and on the research needs to fill
the gaps still hindering the diffusion of the anaerobic process. The first part is focused on the microbiology and extensively
presents and characterises phenol-degrading bacteria and biodegradation pathways. In the second part, dedicated to process
feasibility, anaerobic and aerobic biodegradation kinetics are analysed and compared, and strategies to enhance process performance,
i.e. advanced technologies, bioaugmentation, and biostimulation, are critically analysed and discussed. The final section
provides a summary of the research needs. Literature data analysis shows the feasibility of anaerobic phenol biodegradation at
laboratory and pilot scale, but there is still a consistent gap between achieved aerobic and anaerobic performance. This is why
current research demand is mainly related to the development and optimisation of powerful technologies and effective operation
strategies able to enhance the competitiveness of the anaerobic process. Research efforts are strongly justified because the
anaerobic process is a step forward to a more sustainable approach in wastewater treatment. |
