An enormous amount of synthetic dyes is used annually in the textile, leather, plastics, paper, and dye industries due to their coloring properties. Although dyes give color to materials, they are prone to increase the level of pollution in the environment. The colored wastewater produced in industrial sectors is released into water bodies, posing threats to the ecosystem. To reduce the adverse effects of dyes in the environment, it is necessary to implement feasible and cost-effective strategies. '"Dye Biodegradation Mechanisms and Techniques - Recent Advances'' provides fundamental principles and pathways of bio-based mechanisms in dye removal. This edition firstly discusses dye classification and pollution, then concentrates on the application of fungi, mesophilic bacteria, microflora, and enzymes in dye degradation. This book also highlights the performance of sequential batch reactor systems, moving bed biofilm reactors, and hybrid bioreactors for dye biodegradation​

Recent Advances in Decolorization and Degradation of Dyes in Textile Effluent by Biological Approaches outlines various eco-friendly, cost effective methods for removal of toxic textile dyes. Large amounts of dye are unbound and released into the environment due to inefficient dyeing processes. The release of wastewater containing dye into the environment has several adverse effects as it is toxic, mutagenic and has other undesirable effects on living organisms. Hence, it is necessary to remove these dyes from industrial effluents to have a sustainable environment. This book deals with conventional as well as advanced effective treatment methods for the removal of dyes in order to increase the domain knowledge of readers. Salient features: Describes physico-chemical characteristics of textile effluent, dye classes and toxicity of dyes commonly used in the textile industry Assembles effective approaches which are used to remove dyes from textile effluent prior to their release into the environment Presents several advanced approaches such as genetic engineering, nanotechnology, immobilized cells or enzymes, biofilms and microbial fuel cells, etc. for the removal of dyes.

The use of synthetic chemical dyes in various industrial processes, including paper and pulp manufacturing, plastics, dyeing of cloth, leather treatment and printing, has increased considerably over the last few years, resulting in the release of dye-containing industrial effluents into the soil and aquatic ecosystems. The textile industry generates high-polluting wastewaters and their treatment is a very serious problem due to high total dissolved solids (TDS), presence of toxic heavy metals, and the non-biodegradable nature of the dyestuffs in the effluent. The chapters in this book provide an overview of the problem and its solution from different angles. These problems and solutions are presented in a genuinely holistic way by world-renowned researchers.

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.
