Material-Microbes Interactions: Environmental Biotechnological Perspective brings great insights into microbes-material interactions, biofilm formation, and emerging bioprocess within the field of applied biotechnology. The book systematically summarizes the fundamental principles, the state-of-the-art in microbes-material interaction, and its application in bioprocess and environmental technology development. Understanding the fundamental processes of biofilm formation, the role of material to exchange the energy with microbes, biofilm matrix, and optimization of the biofilm formation process is useful to everyone involved with bioprocess development. This book will be of significant interest to environmental technology developers, researchers, university professors, policymakers, graduate and postgraduate students and other stakeholders. Interestingly, academic institutions, wastewater treatment plants, and research centers have upscaled biofilm-based environmental technologies, such as moving bed bioreactors, microalgae, tricking bed reactors, biofilters, and bioelectrochemical process as promising environmental technologies.

Emerging Technologies and Biological Systems for Biogas Upgrading systematically summarizes the fundamental principles and the state-of-the-art of biogas cleaning and upgrading technologies, with special emphasis on biological processes for carbon dioxide (CO2), hydrogen sulfide (H2S), siloxane, and hydrocarbon removal. After analyzing the global scenario of biogas production, upgrading and utilization, this book discusses the integration of methanation processes to power-to-gas systems for methane (CH4) production and physiochemical upgrading technologies, such as chemical absorption, water scrubbing, pressure swing adsorption and the use of membranes. It then explores more recent and sustainable upgrading technologies, such as photosynthetic processes using algae, hydrogen-mediated microbial techniques, electrochemical, bioelectrochemical, and cryogenic approaches. H2S removal with biofilters is also covered, as well as removal of siloxanes through polymerization, peroxidation, biological degradation and gas-liquid absorption. The authors also thoroughly consider issues of mass transfer limitation in biomethanation from waste gas, biogas upgrading and life cycle assessment of upgrading technologies, techno-economic aspects, challenges for upscaling, and future trends.Providing specific information on biogas upgrading technology, and focusing on the most recent developments, Emerging Technologies and Biological Systems for Biogas Upgrading is a unique resource for researchers, engineers, and graduate students in the field of biogas production and utilization, including waste-to-energy and power-to-gas. It is also useful for entrepreneurs, consultants, and decision-makers in governmental agencies in the fields of sustainable energy, environmental protection, greenhouse gas emissions and climate change, and strategic planning.
