Today synthetic dyes are used extensively in the textile dyeing, paper printing, color photography, pharmaceuticals, food and drink, cosmetic and leather industries. As of now, over 100,000 different dyes are available, with an annual production of over 700,000 metric tons. These industries discharge an enormous amount of colored effluents into natural water bodies, with or without treatment. The textile industry alone discharges 280,000 tons of dyes every year, making it the largest contributor to colored effluent discharge. Although a variety of treatment technologies are available, including adsorption, chemical oxidation, precipitation, coagulation, filtration electrolysis and photodegradation, biological and microbiological methods employing activated sludge, pure cultures, microbial consortia and degradative enzymes are economically viable, effective and environmentally responsible options. As such, this book gathers review articles from international experts working on the microbial degradation of synthetic dyes, offering readers the latest information on the subject. It is intended as a quick reference guide for academics, scientists and industrialists around the world.

Ten years after coming into force of the Stockholm Convention on Persistent Organic Pollutants (POPs), a wide range of organic chemicals (industrial formulations, plant protection products, pharmaceuticals and personal care products, etc.) still poses the highest priority environmental hazard. The broadening of knowledge of organic pollutants (OPs) environmental fate and effects, as well as the decontamination techniques, is accompanied by an increase in significance of certain pollution sources (e.g. sewage sludge and dredged sediments application, textile industry), associated with a potential generation of new dangers for humans and natural ecosystems. The present book addresses these aspects, especially in the light of Organic Pollutants risk assessment as well as the practical application of novel analytical methods and techniques for removing OPs from the environment. Providing analytical and environmental update, this contribution can be particularly valuable for engineers and environmental scientists.

Azo dyes play an important role as coloring agents in the textile, food, and pharmaceutical industry. Due to the toxicity, mutagenicity and carcinogenicity of azo dyes and their breakdown products, their removal from industrial wastewaters has been an urgent challenge. Promising and cost-effective methods are based on their biodegradation, which is treated in this volume. The topics presented by experts in the field include: the classification of azo dyes; toxicity caused by azo dyes; aerobic and anaerobic azo dye biodegradation mechanisms; the role of bacteria, fungi, algae and their enzymes in biodegradation; the impact of redox mediators on azo dye reduction; the integration of biological with physical and chemical processes; the biotransformation of aromatic amines; reactor modelling for azo dye conversion; the biodegradation of azo dyes by immobilized bacteria and fungi; and factors affecting the complete mineralization of azo dyes.

This groundbreaking book covers the recent advances in sustainable technologies and developments, and describes how green chemistry and engineering practices are being applied and integrated in various industrial sectors. Over the past decade, the population explosion, rise in global warming, depletion of fossil fuel resources and environmental pollution have been the major driving force for promoting and implementing the principles of green chemistry and sustainable engineering in all sectors ranging from chemical to environmental sciences. It plays a growing role in the chemical processing industries. Green chemistry and engineering are relatively new areas focused on minimizing generations of pollution by utilizing alternative feedstocks, developing, selecting, and using less environmentally harmful solvents, finding new synthesis pathways, improving selectivity in reactions, generating less waste, avoiding the use of highly toxic compounds, and much more. In an effort to advance the discussion of green chemistry and engineering, this book contains 19 chapters describing greener approaches to the design and development of processes and products. The contributors describe the production of third generation biofuels, sustainable and economic production of hydrogen by water splitting using solar energy, efficient energy harvesting, mechanisms involved in the conversion of biomass, green nanocomposites, bio-based polymers, ionic liquids as green solvents, sustainable nitrogen fixation, bioremediation, and much more. The book aims at motivating chemists and engineers, as well as postgraduate and PhD students and postdocs to pay attention to an acute need for the implementation of green chemistry principles in the field of chemical engineering, biomedical engineering, agriculture, environmental engineering, chemical processing and material sciences.

Bachelor Thesis from the year 2018 in the subject Environmental Sciences, grade: A, course: B. Sc Biotech, language: English, abstract: The experiment was carried out to degrade the dyes by using bacterial isolates extracted from textile dye effluents. Five different bacterial isolates were screened and they have capability to degrade and decolorize the textile dye effluents. In the present study, an attempt was made to examine the potential of isolated bacterium for decolorization of lacto phenol cotton blue, Acetocarmine red & Eriochrome black T in batch reactors. Bacteria from textile waste water were subjected to acclimatization with dyes, in the basal nutrient media. The most promising bacterial isolate was used for further dye degradation studies. Biochemical characteristics revealed the isolated organism as Pseudomonas spp. The optimum pH and temperature for the decolorization was 6.0 and 37°C, respectively. This decolorization potential increased the applicability of this microorganism for the dye removal.

This book presents the complete guide for readers to understand the applications, and pros and cons of nanotechnology applications in environmental remediation, although there are few critical reviews and textbooks available on environmental biotechnology. Water pollution has become one of the biggest concerns of the world. After the industrialisation and urbanisation, environmental pollution has become an enormous concern. Water pollution results in biomagnifications by entering the food chain. As a result water pollution and its risks need to be considered seriously and solutions need to be researched. This volume looks into such topics as bioremediation, nanobiotechnology, biosensors, and enzyme degradation to find solutions to these problems.
