Book Description :

A concise reference on the structural composition and function of microbial communities in coastal environments, especially in relation to natural and anthropogenic impacts. Microbial Communities in Coastal Sediments presents twenty years of coastal microbiology research, grounding it as a vital development in the field of microbial ecology. It is the first book to focus exclusively on the complex microbial ecology and its function in rest of the marine environment. The book outlines the structure, function, and assessment of microbial communities in marine sediments while exploring practical methods of assessment. It is an invaluable resource to aquatic microbiologists, marine ecologists, marine microbiologists, aquatic researchers, and graduate students in this field. Microbial Communities in Coastal Sediments begins with an examination of nutrient sources in the coastal context with a focus on organic matter inputs. The quantity and quality of organic matter in coastal sediments and their impacts on the composition and formation of microbial communities is discussed. The book explores the consequences of anthropogenic changes and human activity on microbial ecology and nutrient cycling. Sections on nutrient availability, green house gas production and biodegradation of persistent organic pollutants provide essential details. Molecular research techniques and methods for assessing microbial community structure and function in coastal sediments are also covered. Explores the interplay of physicochemical and biological features of coastal ecosystems on microbial community composition to provide a template of comparison for field research Includes unique figures, schematic diagrams and photographs related to microbial processes of coastal ecosystem to clearly represent different aspects of microbial structure and functions Provides analytical methods and detailed molecular techniques for qualitative and quantitative analyses of microbial community structure

Book Description :

Microbial Communities in Coastal Sediments: Structure and Functions presents research gained on coastal microbiology over the past two decades. The book covers the source of organic matter, which is found to design sediment microbial communities, and goes on to consider the quality of this matter with regard to degradation in coastal sediment. The book explores human induced changes in coastal ecosystems, then later focuses on the availability of nutrients, source of persistent organic pollutants (POPs) in the sediment, and the sequencing of microbial structures and functions when using molecular tools. Despite the years of research, this is the first book to focus purely on coastal microbes in coastal ecosystems. As such, it is for gaining a better understanding of the diversity and functions of different types of microbes in coastal ecosystems across the globe. The book outlines the microbial community structure in marine sediments while also elaborating on the methods of assessment of the microbial community, making it of great relevance to aquatic microbiologists, marine ecologists, marine microbiologists, aquatic researchers, and scientists alike. Presents data on physico-chemical and biological features of coastal ecosystems and microbial community composition, allowing researchers to compare their data with pre-existing data Includes unique figures, schematic diagrams and photographs related to microbial processes of coastal ecosystems, providing a clear representation on the different aspects of microbial structure and functions Provides analytical methods and detailed molecular techniques for qualitative and quantitative analyses of microbial community structure, enabling scientists and students to follow the protocols provided in the book for assessment in their own research

Book Description :

The overall objective of the research presented here was to combine multiple geochemical parameters and molecular characterizations to provide a novel view of active microbial community ecology of sediments in a large-river deltaic estuary. In coastal and estuarine environments, a large portion of benthic respiration has been attributed to sulfate reduction and implicated as an important mechanism in hypoxia formation. The use of high-resolution sampling of individual sediment cores and high throughput nucleic acid extraction techniques combined with 454 FLX sequencing provided a robust understanding of the metabolically active benthic microbial community within coastal sediments. This was used to provide further understanding and show the importance of simultaneously analyzing the connectivity of sulfur and iron cycling to the structure and function of the microbial population. Although aqueous sulfide did not accumulate in the sediments of the northern Gulf of Mexico, active sulfate reduction was observed in all locations sampled. Microbial recycling and sequestration as iron sulfides prevented the release of sulfide from the sediment. Prominent differences were observed between the sample locations and with depth into the sediment column. This study emphasized the importance of combining novel molecular techniques with simultaneous traditional geochemical measurements to show the interdependence of microbiology and geochemistry. In addition, this study highlights the need to consider microbial community biogeography along with small-scale variations in geochemistry and biology that impact the overall cycling of redox elements when constructing biogeochemical models in marine sediments.

Book Description :

Anaerobic oxidation of methane (AOM) coupled to sulfate reduction (AOM-SR) is a biological process mediated by anaerobic methanotrophs (ANME) and sulfate reducing bacteria. It has scientifi c and societal relevance in regulating the global carbon cycle and biotechnological application for treating sulfate-rich wastewater. This research aimed to enhance the recent knowledge on ANME distribution and its enrichment in different bioreactor confi gurations, i.e. membrane bioreactor (MBR), biotrickling fi lter (BTF) and high pressure bioreactor (HPB). Marine sediment from Ginsburg mud volcano, Gulf of Cadiz was used as inoculum in the BTF and MBR. The BTF operation showed the enrichment of ANME in the biofi lm, especially ANME-1 (40%) and ANME-2 (10%). Whereas, the dominancy of ANME-2 and Desulfosarcina aggregates was observed in the MBR. Moreover, HPB study was performed by using highly enriched ANME-2 community from Captain Arutyunov mud volcano. During the study of HPB at different temperature and pressure conditions, the incubation at 10 MPa pressure and 15 ̊C was observed to be the most suitable condition for the studied AOM-SR community. Furthermore, AOM-SR activity in the coastal sediments from marine Lake Grevelingen (the Netherlands) was explored and the microbial community was characterised which was dominated by ANME-3 among known ANME types.

Book Description :

The main focus of this book is the transport mechanics of sediment particles coated with microbial biofilm, which is called bio-sediment. The book also addresses the question of how to measure and simulate the considerable variation in the properties of natural sediment associated with microbial biofilm, ranging from the micro-scale surface morphology to the macro-scale sediment transport. Nowadays most studies to elucidate the mechanisms of sediment transport have concentrated on physical-chemical sediment properties, little work explicitly coupled sediment dynamics and the environmental effects under the influence of micro-ecosystem, thus leaving a serious gap in water and sediment sciences as well as water ecological research. With respect to physical-chemical sediment properties, this book has been undertaken to evaluate and quantify the effect of biological factors - biofilm on sediment transport mechanics. The chapters cover topics including development of bio-sediment and its properties; model of biofilm growth on sediment substratum; bedform and flow resistance of bio-sediment bed; incipient velocity and settling velocity of bio-sediment; bedload and suspended load transport for bio-sediment; numerical simulation of bio-sediment transport. Besides, the measurement technology, analysis method and expression approach introduced in this book combine the characteristics of hydraulic, environmental and microbial research, having more immediate innovation. This book will be of interest to researchers, managers, practitioners, policy and decision makers, international institutions, governmental and non-governmental organizations, educators, as well as graduate and undergraduate students in the field of hydraulics and river dynamics. It will help to understand the relevance of sediment transport and biofilm growth under the role of aqueous micro-ecosystem, to introduce better tools for the simulation and prediction of bio-sediment transport, and to provide a scientific basis and application foundation for the research of interaction between sediment particles and ecological and environmental factors.

Book Description :

Aquatic ecosystems are currently experiencing unprecedented levels of impact from human activities including over-exploitation of resources, habitat destruction, pollution and the influence of climate change. The impacts of these activities on the microbial ecology of aquatic environments are only now beginning to be defined. One of the many implications of environmental degradation and climate change is the geographical expansion of disease- causing microbes such as those from the Vibrio genus. Elevating sea surface temperatures correlate with increasing Vibrio numbers and disease in marine animals (e.g. corals) and humans. Contamination of aquatic environments with heavy metals and other pollutants affects microbial ecology with downstream effects on biogeochemical cycles and nutrient turnover. Also of importance is the pollution of aquatic environments with antibiotics, resistance genes and the mobile genetic elements that house resistance genes from human and animal waste. Such contaminated environments act as a source of resistance genes long after an antibiotic has ceased being used in the community. Environments contaminated with mobile genetic elements that are adapted to human commensals and pathogens function to capture new resistance genes for potential reintroduction back into clinical environments. This research topic encompasses these diverse topics and describes the affect(s) of human activity on the microbial ecology and function in aquatic environments and, describes methods of restoration and for modelling disturbances.

Book Description :

Based on the material presented at a conference organized by the Centre d’Océanologie of Marseille, held in 2008, this text covers a wealth of hot topics related to the way mankind interacts with the marine environment. With the state of our oceans and seas becoming an increasing source of concern worldwide, this timely addition to the debate features the latest research in both France and Japan. The book’s chapters present work on many of the key areas of oceanographic study. The concept of marine biodiversity is treated, in particular how it is affected by human agency and invasive species, many of which have been introduced anthropogenically. Coastal zones are analyzed in detail, with a focus on the interaction between ports and natural environments, and the ecological and economical consequences of this relationship. A chapter on aquaculture looks at ecologically sound management as well as the preservation of resources. New and emerging technologies that aid our observation of the marine environment are covered, as is the physical, chemical, biological and biogeochemical functioning of natural and man-made environments. Featuring work by some of the leading researchers in the field from both France and Japan, this work demonstrates the strength of the links between the two scientific communities, and is an important contribution to the ongoing discussion on the effects of global warming as well as mankind’s impact on the marine environment we depend on for so much.
