This book was released on 2015 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microbial biodegradation is an increasingly incorporated method of hydrocarbon mineralization during oil spill cleanup. To monitor biodegradation, magnetic susceptibility is a geophysical tool that detects changes in sediments magnetism, possibly caused by microbial activity, for example by anaerobic iron reduction that can induce magnetite formation. Furthermore, the high input of carbon from an oil spill makes other required nutrients, like nitrogen, limiting. The first study goal was to characterize the microbial communities present at high levels of MS with 16S rRNA gene clone libraries at the petroleum contaminated site in Bemidji, Minnesota. Sequences with high similarity to known iron reducers were found. In addition, sequences with high similarity to the syntrophic Smithella and the Archaeon Methanoregula were found, indicating methanogenic oil degradation. In a different approach, bacteria were isolated from the contaminated soil and identified with 16S rRNA sequencing. The second goal was to characterize nitrogen fixing populations present at the oil plume with nifH clone libraries. Sequences with high similarity to the nifH gene of rhizobia and other microorganisms associated with oil degradation were found. These results suggest that an increase in MS is directive towards active biodegradation, and that nitrogen fixation is performed by microorganisms involved in oil degradation.

This book was released on 2015-05-15 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biodegradation mediated by indigenous microbial communities is the ultimate fate of the majority of oil hydrocarbon that enters the marine environment. The aim of this Research Topic is to highlight recent advances in our knowledge of the pathways and controls of microbially-catalyzed hydrocarbon degradation in marine ecosystems, with emphasis on the response of microbial communities to the Deepwater Horizon oil spill in the Gulf of Mexico. In this Research Topic, we encouraged original research and reviews on the ecology of hydrocarbon-degrading bacteria, the rates and mechanisms of biodegradation, and the bioremediation of discharged oil under situ as well as near in situ conditions.

This book was released on 2019-04-05 with total page 295 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine environments are fluid. Microorganisms living in the ocean experience diverse environmental changes over wide spatiotemporal scales. For microorganisms and their communities to survive and function in the ocean, they need to have the capacity to sense, respond to, adapt to and/or withstand periodic and sporadic environmental changes. This eBook collates a variety of recent research reports and theoretical discussions on the ecoenergetic strategies, community structure, biogeochemical and ecosystem functions as well as regulatory processes and mechanisms that marine microorganisms employ in response to environmental gradients and variations.

Available in PDF, EPUB and Kindle. Book excerpt: Marine environment is the largest habitat covering approximately 70% of the total earth surface. Oceans are the main regulatory agent of earth’s climate and harbour a huge diversity of living organisms. Marine environment provide a unique ecological niche to different microbes which play a significant role in nutrient recycling as well as various environmental activities. However with rapid industrialization, urbanisation, ship trafficking and mining activities enormous amounts of waste including heavy metals, hydrocarbons, chemicals, dyes, organic load, agriculture waste, pesticides, antifoulants (e.g. tributyltin) and bacterial pathogens have accumulated in marine/estuarine environments over several decades and pose a serious threat to marine macro and micro biota and humans and therefore require special attention. However some natural marine microbes are known to possess diverse resistance mechanisms and degradation pathways to variety of toxic pollutants and these unique characteristics of marine/estuarine bacteria proved to be an ideal tool in bioremediation of contaminated marine and estuarine environmental sites. Reclamation of marine polluted environments using marine microbes has been found to be effective, affordable and ecofriendly technological solution over conventional physical and chemical methods. Objective of this book is focus on marine pollution and application of marine microorganisms in cost effective and ecofriendly methods of pollution abatement.

Download or read book The Prokaryotes written by Edward F. DeLong and published by Springer. This book was released on 2014-10-13 with total page 567 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Prokaryotes is a comprehensive, multi-authored, peer reviewed reference work on Bacteria and Achaea. This fourth edition of The Prokaryotes is organized to cover all taxonomic diversity, using the family level to delineate chapters. Different from other resources, this new Springer product includes not only taxonomy, but also prokaryotic biology and technology of taxa in a broad context. Technological aspects highlight the usefulness of prokaryotes in processes and products, including biocontrol agents and as genetics tools. The content of the expanded fourth edition is divided into two parts: Part 1 contains review chapters dealing with the most important general concepts in molecular, applied and general prokaryote biology; Part 2 describes the known properties of specific taxonomic groups. Two completely new sections have been added to Part 1: bacterial communities and human bacteriology. The bacterial communities section reflects the growing realization that studies on pure cultures of bacteria have led to an incomplete picture of the microbial world for two fundamental reasons: the vast majority of bacteria in soil, water and associated with biological tissues are currently not culturable, and that an understanding of microbial ecology requires knowledge on how different bacterial species interact with each other in their natural environment. The new section on human microbiology deals with bacteria associated with healthy humans and bacterial pathogenesis. Each of the major human diseases caused by bacteria is reviewed, from identifying the pathogens by classical clinical and non-culturing techniques to the biochemical mechanisms of the disease process. The 4th edition of The Prokaryotes is the most complete resource on the biology of prokaryotes. The following volumes are published consecutively within the 4th Edition: Prokaryotic Biology and Symbiotic Associations Prokaryotic Communities and Ecophysiology Prokaryotic Physiology and Biochemistry Applied Bacteriology and Biotechnology Human Microbiology Actinobacteria Firmicutes Alphaproteobacteria and Betaproteobacteria Gammaproteobacteria Deltaproteobacteria and Epsilonproteobacteria Other Major Lineages of Bacteria and the Archaea

This book was released on 2003 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: "In 1970 the Arrow oil spill off Cape Breton contaminated 305 kilometres of shoreline. Aerial and land surveys have demonstrated that natural weathering has occurred throughout this period, but it was relatively slow, especially in sheltered areas like Black Duck Cove lagoon. This study analyzed the microbial hydrocarbon degradation potential in the lagoon sediments using direct and culture-based techniques. Mineralization of hydrocarbon substrates (hexadecane, octacosane and naphthalene) indicated the presence of an active degradative microbial community, however, genes from known bacterial hydrocarbon degradation pathways (alkB, ndoB, phnAc) were not detected by direct extraction of sediment DNA and PCR amplification. Sediment enrichment cultures had increased mineralization rates for naphthalene and hexadecane, and a hexadecane-degrading pure culture, Rhodococcus sp. BDC14, with a typical alkB gene was isolated. PCR analysis of total community DNA extracted directly from the enrichments indicated the presence of the Alcanivorax borkumensis alkB1 genotype. The results demonstrated that there were notable differences between culture-based and direct molecular analytical techniques in characterizing the contaminated sediments." --
