Download or read book Microbial Action on Hydrocarbons written by Vivek Kumar and published by Springer. This book was released on 2019-02-08 with total page 664 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book discusses ways to overcome the side effects of using hydrocarbon-based products as energy sources. Hydrocarbons produce raw crude oil waste of around 600,000 metric tons per annum, with a range of uncertainty of 200,000 metric tons per year. The various chapters in this book focus on approaches to reduce these wastes through the application of potential microbes, in a process called bioremediation. The book is a one-stop reference resource on the methods, mechanisms and application of the bio-composites, in the laboratory and field. Focusing on resolving a very pressing environmental issue, it not only provides details of existing challenges, but also offers deeper insights into the possibility of solving problems using hydrocarbon bioremediation.
Download or read book Mycorrhizal Technology in Agriculture written by S. Gianinazzi and published by Birkhäuser. This book was released on 2012-12-06 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: Arbuscular Mycorrhiza (AM) is the most common mycorrhizal type involved in agricultural systems, and the most widespread plant root symbiosis. The fungi involved (Glomales) are known to promote plant growth and health by acting as biofertilizers, bioprotectors and bioregulators. The main aim of this book is to provide readers with theoretical and applied knowledge essential for the use of AM fungi in improving plant health and fitness, production of high quality food and in conservation of natural resources. The different chapters target understanding the role of AM fungi in sustainable crop production, discussing ways to improve biological equilibria between microorganisms in the mycorrhizosphere, analysing genetic, physiological, cellular and molecular bases of AM functioning and establishing technologies for inoculum production, according to the regulatory guidelines for application.

This book was released on 2014 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microbial community structure and function are important to ecological processes and to the surrounding physical and chemical environment. Microbes also respond to changes in environmental conditions by oxidizing and transforming pollutants. Sediment contamination is a worldwide problem, yet there is a gap of information about geochemistry and structure of microbial communities in riverbank sediments impacted by long-term pollution. Characterizing the bacterial community in contaminated sediments is critical because it might reveal that some species have adapted to pollution and others can use the xenobiotic as energy and/or carbon sources. We measured high concentrations of polycyclic aromatic hydrocarbons (PAH) in riverbank sediments of the Mahoning River (Ohio, USA) derived from both pyrolytic and petrogenic sources, ranking this sediment as one of the most polluted aquatic ecosystems worldwide. A very high ecological risk to aquatic organisms, even at what was previously considered an unpolluted site was found. Multivariate statistics revealed that bacterial communities followed a temporal and spatial pattern similarly to that found in uncontaminated aquatic environments. PAHs, metals, sulfate, pH, and moisture represented a strong geochemical gradient that likely influenced community composition. Phylogenetic analysis of the 16S rDNA gene revealed groups of bacteria including d-proteobacteria, firmicutes, and bacteriodetes. Some members of these groups have been described as important in PAH degradation. Analysis of the dsrAB gene revealed that most sequences were closely affiliated with unknown, uncultured sulfate reducing bacteria (SRB). Two PAHs were used as models to measure their disappearance over time under sulfate reducing conditions and when a humic acid analogue (anthraquinone-2,6-disulfonate [AQDS]) was added to sediments. After 40-days of anaerobic incubation phenanthrene and fluorene degradation with AQDS was greatly increased in comparison to sediments undergoing natural attenuation. The presence of PAH-degrading and SRB indicated that degradation was likely a biotic mediated process. My research demonstrated that bacterial communities respond to intensive and extensive pollution and are driven by environmental conditions to different extents. In response, microbial communities likely used sulfate and humics for energy and PAHs as carbon sources, contributing to biogeochemical cycling of sulfur and carbon, and providing an important ecosystem function translated as degradation of PAHs.

Available in PDF, EPUB and Kindle. Book excerpt: The book aims to provide a comprehensive view of advanced environmental approaches for wastewater treatment, heavy metal removal, pesticide degradation, dye removal, waste management, microbial transformation of environmental contaminants etc. With advancements in the area of Environmental Biotechnology, researchers are looking for the new opportunities to improve quality standards and environment. Recent technologies have given impetus to the possibility of using renewable raw materials as a potential source of energy. Cost intensive and eco-friendly technology for producing high quality products and efficient ways to recycle waste to minimize environmental pollution is the need of hour. The use of bioremediation technologies through microbial communities is another viable option to remediate environmental pollutants, such as heavy metals, pesticides and dyes etc. Since physico-chemical technologies employed in the past have many potential drawbacks including higher cost, and lower sustainability. So there is need of efficient biotechnological alternatives to overcome increasing environmental pollution. Hence, there is a need for environmental friendly technologies that can reduce the pollutants causing adverse hazards on humans and surrounding environment.
Download or read book Approaches in Bioremediation written by Ram Prasad and published by Springer. This book was released on 2018-12-08 with total page 413 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bioremediation refers to the clean‐up of pollution in soil, groundwater, surface water, and air using typically microbiological processes. It uses naturally occurring bacteria and fungi or plants to degrade, transform or detoxify hazardous substances to human health or the environment. For bioremediation to be effective, microorganisms must enzymatically attack the pollutants and convert them to harmless products. As bioremediation can be effective only where environmental conditions permit microbial growth and action, its application often involves the management of ecological factors to allow microbial growth and degradation to continue at a faster rate. Like other technologies, bioremediation has its limitations. Some contaminants, such as chlorinated organic or high aromatic hydrocarbons, are resistant to microbial attack. They are degraded either gradually or not at all, hence, it is not easy to envisage the rates of clean-up for bioremediation implementation. Bioremediation represents a field of great expansion due to the important development of new technologies. Among them, several decades on metagenomics expansion has led to the detection of autochthonous microbiota that plays a key role during transformation. Transcriptomic guides us to know the expression of key genes and proteomics allow the characterization of proteins that conduct specific reactions. In this book we show specific technologies applied in bioremediation of main interest for research in the field, with special attention on fungi, which have been poorly studied microorganisms. Finally, new approaches in the field, such as CRISPR-CAS9, are also discussed. Lastly, it introduces management strategies, such as bioremediation application for managing affected environment and bioremediation approaches. Examples of successful bioremediation applications are illustrated in radionuclide entrapment and retardation, soil stabilization and remediation of polycyclic aromatic hydrocarbons, phenols, plastics or fluorinated compounds. Other emerging bioremediation methods include electro bioremediation, microbe-availed phytoremediation, genetic recombinant technologies in enhancing plants in accumulation of inorganic metals, and metalloids as well as degradation of organic pollutants, protein-metabolic engineering to increase bioremediation efficiency, including nanotechnology applications are also discussed.
