Book Description
In the context of wastewater treatment, Bioelectrochemical Systems (BESs) have gained considerable interest in the past few years, and several BES processes are on the brink of application to this area. This book, written by a large number of world experts in the different sub-topics, describes the different aspects and processes relevant to their development. Bioelectrochemical Systems (BESs) use micro-organisms to catalyze an oxidation and/or reduction reaction at an anodic and cathodic electrode respectively. Briefly, at an anode oxidation of organic and inorganic electron donors can occur. Prime examples of such electron donors are waste organics and sulfides. At the cathode, an electron acceptor such as oxygen or nitrate can be reduced. The anode and the cathode are connected through an electrical circuit. If electrical power is harvested from this circuit, the system is called a Microbial Fuel Cell; if electrical power is invested, the system is called a Microbial Electrolysis Cell. The overall framework of bio-energy and bio-fuels is discussed. A number of chapters discuss the basics – microbiology, microbial ecology, electrochemistry, technology and materials development. The book continues by highlighting the plurality of processes based on BES technology already in existence, going from wastewater based reactors to sediment based bio-batteries. The integration of BESs into existing water or process lines is discussed. Finally, an outlook is provided of how BES will fit within the emerging biorefinery area.

Book Description
This book is the first in a two-volume set devoted to bioelectrochemical systems (BESs) and the opportunities that they may offer in providing a green solution to growing energy demands worldwide. In this first volume, established research professionals explain the underlying principles and processes of BESs, providing a thorough introduction to these systems before proceeding to address the roles of cathode catalysts and biocatalysts, biofilms, heterotrophic denitrification, and nanotechnology approaches. This volume forms a sound foundation for understanding the potential industrial applications of this technology, which include in particular the generation of high-value chemicals and energy using organic wastes. These applications are the focus of the second volume, where readers will find up-to-date information on microbial fuel cells and the use of microbial biofilm- and algae-based bioelectrochemical systems for bioremediation and co-generation of valuable chemicals. The book is designed for a broad audience, including undergraduates, postgraduates, energy researchers/scientists, policymakers, and anyone else interested in the latest developments in this field.

Book Description
This book is the second in a two-volume set devoted to bioelectrochemical systems (BESs) and the opportunities that they may offer in providing a green solution to growing energy demands worldwide. While the first volume explains principles and processes, in this volume established research professionals shed light on how this technology can be used to generate high-value chemicals and energy using organic wastes. Bioelectricity is generated in microbial fuel cells (MFCs) under oxygen-depleted conditions, where microbial bioconversion reactions transform organic wastes into electrons. Dedicated chapters focus on MFCs and state of the art advancements as well as current limitations. In addition, the book covers the use of microbial biofilm- and algae-based bioelectrochemical systems for bioremediation and co-generation of valuable chemicals. A thorough review of the performance of this technology and its possible industrial applications is presented. The book is designed for a broad audience, including undergraduates, postgraduates, energy researchers/scientists, policymakers, and anyone else interested in the latest developments in this field.

Book Description
The six years that have passed since the publication of the first edition have brought significant advances in both biofilm research and biofilm engineering, which have matured to the extent that biofilm-based technologies are now being designed and implemented. As a result, many chapters have been updated and expanded with the addition of sections reflecting changes in the status quo in biofilm research and engineering. Emphasizing process analysis, engineering systems, biofilm applications, and mathematical modeling, Fundamentals of Biofilm Research, Second Edition provides the tools to unify and advance biofilm research as a whole. Retaining the goals of the first edition, this second edition serves as: A compendium of knowledge about biofilms and biofilm processes A set of instructions for designing and conducting biofilm experiments A set of instructions for making and using various tools useful in biofilm research A set of computational procedures useful in interpreting results of biofilm research A set of instructions for using the model of stratified biofilms for data interpretation, analysis, and biofilm activity prediction

Book Description
The discovery of the ability of microorganisms to exchange electrons with inert electrodes - called electrochemically-active biofilms (EABs) - has triggered new areas in fundamental and applied research. However, advancements in the field have been limited by the scope of available technologies and techniques to study, control and scale up EABs. The overall goal of this dissertation was to address some of the bottlenecks limiting the implementation of bioelectrochemical systems in practical applications. This dissertation presents four examples of such bottlenecks. First, we evaluated field performance of sediment microbial fuel cells (SMFCs) using a novel autonomous, battery-operated device. This research allowed us to determine optimum conditions for energy harvesting from SMFCs constructed in Hot Lake, a remote hypersaline lake in northern Washington. Second, we extended this work to address the limited number of isolated microorganisms known to form EABs, which limits the number and diversity of metabolic traits accessible through microbial electrochemistry. This was done by performing long-term chronoamperometric enrichment in a remote area using a newly developed cost-effective battery-operated deployable potentiostat. We demonstrated its utility through the enrichment of microbial community in four alkaline hot springs in the Heart Lake Geyser Basin in Yellowstone National Park, Wyoming. Third, we addressed the limited strategies to control the potential of MFCs, especially when the reactor feed exhibits high daily and seasonal fluctuations in influent flow rate and characteristics, such as the case in MFCs treating real municipal wastewater. To address this, we developed a switchable dual mode system capable of treating wastewater in self-powered MFC mode as well as under potentiostatic control of anodes and cathodes. We demonstrated this system through the operation of a large laboratory scale reactor and pilot scale operated in a local municipal wastewater treatment plant. Lastly, we investigated the factors affecting the scale up of oxygen reducing cathodic biofilms. This addresses the practical challenges in scaling up bioelectrochemical systems, as previous literature documented a significant decrease in current density when increasing electrode surface area. Collectively, this dissertation presents novel technologies and techniques aimed toward expanding the scope and facilitating practical implementation of bioelectrochemical systems.

Book Description
This book represents a novel attempt to describe microbial fuel cells (MFCs) as a renewable energy source derived from organic wastes. Bioelectricity is usually produced through MFCs in oxygen-deficient environments, where a series of microorganisms convert the complex wastes into electrons via liquefaction through a cascade of enzymes in a bioelectrochemical process. The book provides a detailed description of MFC technologies and their applications, along with the theories underlying the electron transfer mechanisms, the biochemistry and the microbiology involved, and the material characteristics of the anode, cathode and separator. It is intended for a broad audience, mainly undergraduates, postgraduates, energy researchers, scientists working in industry and at research organizations, energy specialists, policymakers, and anyone else interested in the latest developments concerning MFCs.
