Dear Professor/Scientists/ Researchers/Colleagues, As per your expertise, it is our pleasure to invite you to contribute your paper for consideration in the present Call for Papers for the Special Issue: Biotransformation of emerging environmental pollutants to be published in the International Journal of Applied Microbiology and Biotechnology, Springer, with Impact factor- 4.813. Special Issue Information The presence of Emerging Pollutants (EPs) in the environment has been consistently documented as a universal concern. Still, quite limited information is available on the EPs exposure, its fate in the environment, especially its impact on microorganisms and human health. It is still unclear how EPs-induced changes in microbial habitat, diversity, metabolism and their tolerance. The exposure to these EPs, at a minute concentration, may change the microbial biodiversity affecting their specific function in the ecological niches. As a consequence of these deviations’ significant imbalance in the functional biodiversity of the environment and the native colonizing microorganism may occur. The special issue will discuss the current and up-coming EPs, their bioaccumulation; toxicity to biotic components in the ecosystem. This issue will elaborate on the possible biodegradation pathways as a sustainable approach. Detoxification of pollutants by the advanced bio-based technologies are relevant and desirable but may be more challenging than conventional methods. Bioremediation of pollutants are eco-friendly, proficient and financially flexible in removal of environmental pollutants. This special issue will cover different aspects related to the bioremediation-based biotransformation and management of emerging pollutants in waters, soil and sediments. Pollutants may include (but not limited to) organic and inorganic chemicals, biomedical and pharmaceuticals, potentially toxic metals, microplastics, nanoparticles, micro-pollutants, aerosols etc. Contaminant’s biotransformation is immensely dependent upon the concentration of the pollutant, relevant microbes and their degrading abilities, activities, and suitable environmental conditions. In this perception, this special issue will highlight the present current mechanism and advanced technologies that will corelate extreme environmental microbes and their biotransformation abilities of complex EPs even at minute concentrations. Focus will be on recent advances in biodegradation technologies, process engineering aspects of treatment processes and on the engineered applications rather than the fundamental science. The VSI will cover the following topics: Ø Biodegradation of environmental pollutants including emerging micropollutants, Ø Novel and hybrid water treatment technologies for EPs removal, Ø Mechanistic investigations into biotransformation of pollutants at trace concentrations, Ø Process optimization for the removal of pollutants at higher efficiencies, Ø Development of industrial technology for the removal of pollutants, Ø Investigation of metabolic biodegradation pathways, Ø Bioreactors for resource recovery and recycling of valuables from wastes, Ø Advanced omics approaches for investigation microbial biodiversity analysis and their relation to pollution degradation, Ø Contaminant degradation community structure and analysis of microbiome biodegrading single pollutant or pollutants mixture, Ø Understanding the fate, transportation, deposition and removal of environmental pollutants, Ø Advanced research studies on biochemical and engineering aspects of pollutants biotransformation, Ø Case studies and commercial applications.
