Book Description
This book is the first volume of a two-volume set summarizing 40 years of key research findings directly related to metal-resistant Cupriavidus/Ralstonia (Betaproteobacteria). In this first volume, the historical and geographical context of these bacteria, which are mostly found in industrial and polluted environments linked to zinc and other non-ferrous metallurgy, is sketched to illustrate the interactions between bacteria and human activities and the possible evolutionary consequences on bacterial genomes especially as far as the association of metal resistance genes with mobile genetic elements is concerned. A detailed description of the response and underlying genetic determinants of type strain Cupriavidus metallidurans CH34 to a variety of metals is provided. With high level resistance to cadmium, chromate, cobalt, copper, mercury, nickel, lead and zinc mediated by well-known genes for detoxification carried by its megaplasmids pMOL28 and pMOL30. This description is complemented with the genomic context of the metal response genes in C. metallidurans CH34 with a focus on its mobilome including insertion sequence elements, transposons, integrative and conjugative elements and genomic islands. In addition, in the second volume, structural and catalytic data from bacterial primary and secondary transporters (P-ATPases, tripartite chemiosmotic cation/proton efflux systems, cation diffusion facilitators, Major Facilitator Superfamily and some minor categories) are outlined and detailed for the corresponding C. metallidurans proteins. The available three-dimensional structures of C. metallidurans proteins are reviewed in detail, including RND and membrane fusion proteins (from tripartite chemiosmotic cation/proton efflux systems), sigma and anti-sigma regulatory proteins of the cnr efflux system (resistance to cobalt and nickel) and various periplasmic proteins mainly involved in the response to copper and mercury.

Book Description
The importance of understanding metal–microbe interactions underlies a number of social–economic issues in the world. The antimicrobial resistance era has created a need for novel antimicrobials and within this fieldm metal and metalloid ions are promising solutions. Pollution sites, either co-contaminated with metals or with metals as the sole pollutant, contain microbes that are present as key participants, with both of these issues habing links to agriculture. Microbes also play key roles in the global geochemical cycle of many elements. Such statements solidify the need to understand metal–microbe interactions. Given that genomics has arguably become the most useful tool in biology, the application of this technology within the field of understanding metal resistance comes as no surprise. Whilst by no means comprehensive, this book provides examples of the applications of genomic approaches in the study of metal–microbe interactions. Here, we present a collection of manuscripts that highlights some present directions in the field. The book starts with a collection of three papers evaluating aspects of the genomics of the archetype metal resistant bacteria, Cuprividus metallidurans. This is followed by four studies that evaluate the mechanisms of metal resistance. The next two papers assess metal resistance in agricultural related situations, including a review on metal resistance in Listeria. The book concludes with a review on metal phytoremediation via Rhizobia and two subsequent studies of metal biotechnology relevance.

Book Description
Pollution due to various anthropogenic activities continues to increase. In terms of water pollutants, organic and inorganic pollutants are the most problematic. Although several measures have been proposed and implemented to prevent or reduce contamination, their increased concentration in water bodies has created serious concerns. Over the years, the problem has been aggravated by industrialization, urbanization and the exploitation of natural resources. The direct discharge of wastewater contaminants and their geographical mobilization have caused an increase in concentration in ground, surface, fluvial and residual waters. Extensive information about detection and disposal methods is needed in order to develop technological solutions for a variety of environments, both urban and rural. This book provides up-to-date information on wastewater contaminants, aimed at researchers, engineers and technologists working in this field. Conventional physicochemical techniques used to remove contaminants from wastewater include ion exchange, precipitation, degradation, coagulation, coating, membrane processes and adsorption. However, these applications have technological and economic limitations, and involve the release of large amounts of chemical reagents and by-products that are themselves difficult to remove. Biosorption - the use of organically generated material as an adsorbent – is attracting new research and scholarship. Thermally-treated calcined biomaterials may be treated to remove heavy metals from wastewater. To ensure the elimination of these contaminants, existing solutions must be integrated with intelligent biosorption functions. Biosorption for Wastewater Contaminants will find an appreciative audience among academics and postgraduates working in the fields of environmental biotechnology, environmental engineering, wastewater treatment technology and environmental chemistry.

Book Description
Municipal and industrial wastewaters contain a wide spectrum of pollutants. Their effective removal presents a challenge for water treatment technology. Biosorption of nutrients and pollutants has been used in sewage treatment since the discovery of the activated sludge process. It is a passive uptake process by which pollutants are adsorbed on the surface of cell walls and/or dissolved in structures of microorganism cells that are present in sludge. Sorbed pollutants remain in the sludge and can be potentially released back into the environment depending on their condition and the reversibility of the pollutant-sludge interaction. An overview of typical biosorption applications for the removal of nutrients, organic pollutants, and metals in wastewater treatment is provided in different areas of their use for the protection of aquatic ecosystems and human health. This book will be of interest to operators of wastewater treatment plants and sludge treatment and disposal facilities as well as to researchers and university students in the field of environmental engineering.

Book Description
Algae Mediated Bioremediation Develop new methods for remediating pollution with this cutting-edge guide In a world where environmental remediation and pollution removal are becoming more critical with every passing day, the search for organic and sustainable solutions has never been more critical. Removing organic pollutants through the use of algae has become an especially promising avenue for bioremediation, with a far lower environmental impact than comparable mechanical, physical, or chemical approaches. The possibility of deriving bioenergy from the resulting biomass makes this approach even more potentially critical to a sustainable future. Algae Mediated Bioremediation offers a cutting-edge overview of these processes and their applications. Its comprehensive approach to the problems of pollution abatement and the value of algae as environmental and biotechnological agents include both practical solutions and key gaps in existing research. Algae Mediated Bioremediation readers will also find: Case studies of successful use drawn from across the globe Detailed discussion of remediating aquatic, atmospheric, and terrestrial habitats Applications for value-added products incorporating biomass Algae Mediated Bioremediation is ideal for biotechnologists, biochemists, natural products chemists, and other researchers working in industry or environmental research.
