Biofilms in aquatic ecosystems colonize various surfaces (sand, rocks, leaves) and play a key role in the environment. Aquatic biofilms supply energy and organic matter to the food chain, they are important in recycling organic matter, and they contribute to water quality. This book is a concise review of the current knowledge on aquatic biofilms, with an emphasis on the characteristics and ecology of biofilms in natural ecosystems, along with a focus on biofilm applications linked to water pollution problems. The book is divided into three sections: "Biofilms Mode of Life," "Biofilms and Pollution," and "New Technologies Using Biofilms." In the first section, the aquatic biofilm mode of life is described and reviewed. Key aspects covered include the three-dimensional structure and cell-to-cell communication of biofilms, their dynamic prokaryotic diversity, and their vital role in biogeochemical cycles. This is followed by a comprehensive look at the use of biofilms in water quality. Additional chapters discuss environmental risk assessment, monitoring, and ecotoxicological approaches. Further topics include biofilm development in sewage pipes and the potential for microbial transformations in these systems. The final section focuses on important examples of novel technologies based on biofilms for water treatment, including the biodegradation of pollutants, the application of bioelectrogenic biofilms, and the biofilm capacity for nitrogen removal.

Aquatic Ecosystems and Microbial Biofilms: Significance, Dynamics, Prevention and Control provides a systematic introduction and review of state-of-the-art information on microbial biofilms in aquatic ecosystems and their control. The book is designed and developed to understand the microbial biofilms in aquatic ecosystems, their role, and the control strategies. The contents of the book are well discussed to get state-of-art knowledge on various topics such as the role of biofilms in marine ecosystems, microbial biofilms, and drinking water systems, biofilms in biofouling and biocorrosion, beneficial aspects of biofilms such as biogeochemical cycling, wastewater treatment, and in biodeterioration of organic materials. This book also provides comprehensive knowledge and in-depth scientific information on the role of biofilms and their contribution to antibiotic resistance, and also advanced technologies to understand biofilms such as metagenomics. The book offers comprehensive coverage of the most essential topics, including: Microbial biofilms in aquatic ecosystems. New horizons to understand the role of biofilms in biofouling and corrosion and their control measures. Beneficial role of aquatic biofilms such as in biogeochemical cycling,wastewater treatment, and biodeterioration of organic materials. Various strategies to collaborate interdisciplinary schemes worldwide to design and develop new methods for cleaner drinking water, and information on advanced techniques such as metagenomics to understand the diversity and functional role of aquatic biofilms. This book serves as a reference book for scientific investigators who would like to study biofilms in aquatic ecosystems, as well as researchers developing methodology in this field to study biofilm formation in aquatic ecosystems, their advantages and disadvantages, and control strategies.

Environmental DNA (eDNA) refers to DNA that can be extracted from environmental samples (such as soil, water, feces, or air) without the prior isolation of any target organism. The analysis of environmental DNA has the potential of providing high-throughput information on taxa and functional genes in a given environment, and is easily amenable to the study of both aquatic and terrestrial ecosystems. It can provide an understanding of past or present biological communities as well as their trophic relationships, and can thus offer useful insights into ecosystem functioning. There is now a rapidly-growing interest amongst biologists in applying analysis of environmental DNA to their own research. However, good practices and protocols dealing with environmental DNA are currently widely dispersed across numerous papers, with many of them presenting only preliminary results and using a diversity of methods. In this context, the principal objective of this practical handbook is to provide biologists (both students and researchers) with the scientific background necessary to assist with the understanding and implementation of best practices and analyses based on environmental DNA.

Slime is the less polite term, and many industries are plagued by it on metal and plastic surfaces where it fouls, reduces heat transfer, corrodes, liberates noxious gases, and can serve as a reservoir for pathogens. Researchers and practitioners take a broader view here than most studies, which are limited to monocultures of micro-organisms relevant to clinical settings, by considering the phenomenon in the aquatic environment and as it affects natural water, drinking water, and process water systems. The 24 papers include discussions of structure and influences on biofouling under laminar and turbulent flows, physiological heterogeneity and biofilm control, process and industrial waters, biofouling in reverse osmosis systems, the oil industry, cooling tower systems, associated pathogens and metabolites, detecting and characterizing biofilms by mass transport analysis, and a standard method to evaluate aquatic biofilms.

This book is open access under a CC BY 4.0 license. This volume focuses on microscopic plastic debris, also referred to as microplastics, which have been detected in aquatic environments around the globe and have accordingly raised serious concerns. The book explores whether microplastics represent emerging contaminants in freshwater systems, an area that remains underrepresented to date. Given the complexity of the issue, the book covers the current state-of-research on microplastics in rivers and lakes, including analytical aspects, environmental concentrations and sources, modelling approaches, interactions with biota, and ecological implications. To provide a broader perspective, the book also discusses lessons learned from nanomaterials and the implications of plastic debris for regulation, politics, economy, and society. In a research field that is rapidly evolving, it offers a solid overview for environmental chemists, engineers, and toxicologists, as well as water managers and policy-makers.

This textbook on biofilms combines knowledge on sub-aquatic and sub-aerial biofilms and their products (stromatolites, oolites, ore, petroleum and gas deposits). It describes how formation and degradation of minerals and rocks is achieved through biofilm formation on and in sediments, soils and rocks. Methods of study, examples of Precambrian biofilms of an early Earth as well as the most recent examples of desert rock biofilms are treated in this integrative book on biofilms, microbial mats and stromatolites.

With an increasing population, use of new and diverse chemicals that can enter the water supply, and emergence of new microbial pathogens, the U.S. federal government is faced with a regulatory dilemma: Where should it focus its attention and limited resources to ensure safe drinking water supplies for the future? Identifying Future Drinking Water Contaminants is based on a 1998 workshop on emerging drinking water contaminants. It includes a dozen papers that were presented on new and emerging microbiological and chemical drinking water contaminants, associated analytical and water treatment methods for their detection and removal, and existing and proposed environmental databases to assist in their proactive identification and regulation. The papers are preceded by a conceptual approach and related recommendations to EPA for the periodic creation of future Drinking Water Contaminant Candidate Lists (CCLsâ€"produced every five yearsâ€"include currently unregulated chemical and microbiological substances that are known or anticipated to occur in public water systems and that may pose health risks).
