“…This group of microorganisms is central to the global carbon cycle as a result of their ability to mineralize the complex polymeric woody plant material lignin (Kuhad et al 2004). Fungi, due to their excretion of extracellular enzymes, are known to be able to degrade-though possibly not completelystructures that are difficult for bacteria to handle (Forss and Welander 2009). Wood-rotting microorganisms may be good candidates for biodegradation of synthetic dyes.…”

“…Wood-rotting microorganisms may be good candidates for biodegradation of synthetic dyes. This is because lignocellulose-containing materials consist partly of complex molecules with similar structures as textile dyes, which might make the microorganisms growing on these materials adapted to refractory organic compounds (Forss and Welander 2009). Table 2 presents a summary of some studies on biodegradation of dyes by fungi.…”

“…It is very important to analyze the treated water with regard to the dye content as well as intermediates, especially aromatic amines, since some are considered carcinogenic (Forss and Welander 2009). The removal of color from dye-containing wastewater may be the first and a major concern (Sun et al 2009), but the aim of biodegradation of dyes is not only to remove the color but also to eliminate or substantially decrease the toxicity of the dyes (detoxification).…”

The contamination of soils and waters by dye-containing effluents is of environmental concern. Due to the increasing awareness and concern of the global community over the discharge of synthetic dyes into the environment and their persistence there, much attention has been focused on the remediation of these pollutants. Among the current pollution control technologies, biodegradation of synthetic dyes by different microbes is emerging as an effective and promising approach. The bioremediation potentials of many microbes for synthetic dyes have been demonstrated and those of others to be explored in future. The biodegradation of synthetic dyes is an economic, effective, biofriendly, and environmentally benign process. Bioremediation of xenobiotics including synthetic dyes by different microbes will hopefully prove a green solution to the problem of environmental soil and water pollution in future. This review paper discusses comprehensively the science and arts of biodegradation of synthetic dyes.

White rot fungi (WRF) produce various isoforms of extracellular peroxidases (lignin peroxidase-LiP and manganese peroxidase-MnP) and phenoloxidases (laccases), which are involved in the degradation of lignin in their natural lignocellulosic substrates. This ligninolytic system of WRF is directly involved in the degradation of various xenobiotic compounds and dyes. Liquid fermentation or solid-state fermentation techniques can be used for enzyme production. Crude enzymes or purified enzymes of WRF can be used for decolorization of azo dyes. Repeated-batch decolorization technique is a new approach that can be used for decolorization. There are different procedures to determine the enzyme(s) responsible for decolorization. Single step isolation and identification procedure (SSIIP) is a new and simple method that can be used for detection of the enzyme responsible for biodegradation of azo dyes.

“…The number of synthetic textile dyes used today exceeds 100,000 (Rai et al 2005;Forss and Welander 2009). More than 50% of about 1 million tons of the dyes produced annually are categorized as azo dyes, which are characterized by one or more nitrogen-to-nitrogen double bonds (-N=N-) in their chemical structures (Isik and Sponza 2004;Kumar et al 2006).…”

Synthetic dyes are extensively used in textile dyeing, paper printing, color photography, and the pharmaceutical, food, cosmetic, and leather industries. Most synthetic dyes are toxic and highly resistant to removal due to their complex chemical structures. There is a need for investigation of the biological treatment of synthetic dyes at a low cost and in the shortest possible time; synthetic dyes are used especially in the dye and textile industries and are an important polluting agent in the wastewater dumped into the environment by these industries. White rot fungus contains a variety of extracellular enzymes, and these enzymes are used for biological degradation of organic matter. The aim of the present work is to evaluate removal of the textile dye Turquoise Blue HFG by Coprinus plicatilis. Coprinus plicatilis was able to enzymatically decolorize 100% of the dye (dye concentration 10.0 and 25.0 mg L ¡1 ). Ultraviolet-visible (UV-vis) spectrophotometric analyses, before and after decolorization, suggest that decolorization was due to biodegradation. There was an attempt to identify metabolites with Fourier transform infrared (FT-IR) spectroscopy and gas chromatography-mass spectrometry (GC-MS) at the end of the decolorization process. These results indicate that the samples did not include any detectable metabolite. Therefore, this fungus can be used as an economical and eco-friendly tool to minimize the pollution by industries to a significant extent.
