About the book
Anaerobic digestion of biomass to methane and carbon dioxide is promoted by the activity and interactions of many different physiological groups of microorganisms that form specialized microbial communities. They are responsible for four steps of AD: hydrolysis of polymeric organic matter to monomers, acidogenesis (acidic fermentations), acetogenesis (degradation of acidic fermentation products to dioxide, hydrogen and acetic acid, substrates for methanogenesis) and the last step - methanogenesis when finally methane is formed. AD is a key process in the global carbon cycle and energy flow in ecosystems. It commonly occurs in natural anoxic ecosystems such as freshwater sediments, wetlands, marshlands, deeper zones of marine sediments and extreme environments, e.g. hydrothermal vents. Biomethane and carbon dioxide are generated in built-enviroments such as paddy fields, landfill sites, anaerobic wastewater treatment plants, biogas plants, innovative installations where biogas is used by man for green energy production.
The idea of this book is to present the enviroments where biomethane is formed with a special focus on characteristics of microbial communities and interactions between microorganisms, use of metaomic approaches to study anaerobic digestion microbiomes, recognition of factors determining efficiency of biogas production, technical solutions and methods of biogas (biomethane) recovery and use for energy generation.
