Special Issue Information
Dear Colleagues,
Wastewater treatment facilities in China must produce a significant amount of sewage sludge due to the country's rapid urbanization and the rise in urban wastewater. This sludge contains potential resources including organic materials, nutrients, metals, and bioenergy that can be recovered. A variety of technologies are available for the resource utilization of sludge, and anaerobic treatment technologies are the main methods for pollutant decomposition and energy recovery in sewage sludge disposal. For the directional regulation of the sludge microbial community and effective enhancement of sludge treatment performance, an in-depth understanding of the population structure and functional genes of microorganisms in anaerobic digestion is crucial. Meanwhile, the rapid development of high-throughput sequencing technology has provided a powerful means to analyze the composition and dynamics of sludge microbial communities, identify functional microbial bacteria and functional genes, and study the interactions between microorganisms. However, based on the synergistic effect of functional microorganisms, many studies of other emerging sludge biotreatment technologies, such as bioelectrochemical regulation, have also shown great promise for simultaneous waste biorefining, chemical synthesis, and clean electrofuel generation. In addition, the mining of functional microbial properties in sludge treatment systems can also lead to the discovery of novel microorganisms with the function of degrading toxic and hazardous substances, thus facilitating the application of microbial remediation technologies.
This Special Issue will focus on innovative research communications dedicated to the role of microbial fermentation in helping sewage sludge treatments deliver their full potential as biorefineries and actors in the bioeconomy. Contributions are welcomed on both the micro-scale (investigations into the microbial communities and their biochemical, metabolic, and genomic characteristics) and the macro-scale (technology development, optimization, integration, and environmental, economic, and technological assessment).

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Fermentation is an international peer-reviewed open access monthly journal published by MDPI.
