The increasing generation of wastes, e.g. organic solid wastes and industrial and domestic wastewater, posed great environmental pollution and ecological risks. Meanwhile, the scarcity of resources and energy drive the public to seek more efficient and sustainable treatment approaches for pollution elimination and resource recovery. Based on the activity and metabolism of microorganisms, biological treatment has been widely accepted as an eco-friendly and effective strategy for pollutants decomposition. Moreover, high-value products and energy could be recovered via biological transformation. The functional microorganisms and their metabolic functions and activities play vital roles in the transformation processes of wastewater treatment and organic solid wastes disposal, and they are closely associated with the efficiency of wastes removal or valorization. Therefore, effectively regulating and maintaining the high metabolic activity and functions of microorganisms involved in these environmental processes is of vital importance. Also, the disclosure of underlying mechanisms by advanced techniques and methods at the levels of the microbial community, metabolic pathways, genetic expression levels were urgent to reveal. The relevant studies will benefit the increased yield of value-added products and improved sustainability of pollution control.
The Research Topic aims to provide an insight into the latest findings on the organic matter removal or transformation driven by specialized pure or mixed microbial cultures, including the biological volatile fatty acids, methane and polyhydroxyalkanoates (PHA) production from organic solid waste, and the biotechnologies related to efficient pollutants removal, nutrients recovery and water reclamation in wastewater treatment. Great emphasis should be placed on the illustration of the specific microbial functions in microbial consortia, elucidation of the biological principles and main controlling factors that regulate the metabolic bioprocesses, and provision of biotechnological solutions and regulation strategies, which would provide upgrading concepts and technical supports for the sustainable treatment of wastewater and organic wastes treatment with maximized both environmental and economic benefits.
We ask for research papers and reviews on the microorganism mechanism or biotechnology for sustainable wastewater treatment and organic wastes valorization, including but not restricted to the following topics. Manuscripts dealing with meta-omics methodologies and in situ detection of microbial biomarkers are also encouraged.
• Innovative aerobic or anaerobic biotechnology for municipal and industrial wastewater treatment;
• Biological transformation of emerging pollutants (i.e. antibiotics, ARGs and microplastics) in wastewater or solid waste;
• Biological technology for resources and energy recovery (i.e. hydrogen, Volatile fatty acids, PHAs) from wastes;
• Hybrid/integrated biological/chemical/physical treatment approaches for wastewater and organic wastes treatment
• The applications of innovative tools or techniques (i.e. machine learning, multi-omics) to reveal the microbiological mechanisms for wastewater treatment and organics valorization
• Engineered microbiomes and synthetic biology for organic matter removal or transformation
• Microbial diversity and interaction in complex environmental processes
