“…Crude enzyme of T. versicolor U97 was used to detect the metabolite produced during decolorization of Reactive Green 19 using HPLC analysis. HPLC elution profile of the dye during the incubation period was changed, suggesting a change in the aromatic character of the initial dye [33]. In the HPLC analysis, a peak at a retention time of 8.7 min represented Reactive Green 19 solution at 0 h (Fig.…”

“…After 24 h, several peaks corresponding to various metabolites were observed at a lower retention time, indicating the formation of more polar oxidation products than the original dye ( Fig. 4(B)) [33]. However, a detailed investigation to determine the identity of these metabolites of Reactive Green 19 decolorization is pending.…”

immobilized fungi by approximately 80%, which is a twofold improvement over decolorization without mediators. In bioreactor system, decolorization of Reactive Green 19 was increased to 82% after 72 h. We evaluated the efficiency of the decolorization model for use in a small industry. Our results indicated that the wastewater discharge of 10 m 3 d −1 requires a reactor volume of 24 m 3 to obtain 80% decolorization with a retention time of 1.75 d. This study identifed that bioreactor of T. versicolor U97 immobilization is the most promising method for use in decolorize Reactive Green 19 and may be suitable for the treatment of wastewater in small industries.

“…Similar applications of enzyme mediated bioremediation was demonstrated for decolorizing Remazol Brilliant Blue-R dye using three basidiomycetes isolated from marine sponges [39], and anthraquinone dye Reactive Blue 4 by C. unicolor, a marine white-rot basidiomycete. Gao et al [40] proposed that biostimulation and bioaugmentation could affect the biotransformation of persistent organic pollutants (POPs) such as PCB 118 by two marine fungi belonging to genus Penicillium in presence of maifanite [41]. Another POP, pentachlorophenol was shown to be biotransformed at high concentrations by marine-derived fungus, Trichoderma harzianum [42].…”

“…One such application was its demonstration in recycled paper industry for deinking of offset printed paper wherein laccases from three basdiomycetes (Trametes villosa, Coriolopsis rigida, Pycnoporus coccineus) and one ascomycete (Myceliopthora thermophila) were assayed for decolourization of flexographic inks in presence of synthetic and artificial mediators [102]. The resistance of textile dyes to fading on exposure to sunlight, water, and their persistence in environment due to synthetic origin is a cause for concern owing to their toxicity Verma et al [41] and Vishwanath et al [101] for the first time reported the marine fungal laccase mediated decolourization, detoxification, and mineralization of Reactive Blue 4 at relatively high concentrations of 1000 mg/L. Studies on degradation of Bisphenol A, an endocrine disrupting chemical by laccase purified from Fusarium incarnatum showed that 91.43 % of 200 mg/L Bisphenol A was eliminated when incubated with laccase [103].…”

Bioremediation refers to cost-effective and environment-friendly method for converting the toxic, recalcitrant pollutants into environmentally benign products through the action of various biological treatments. Fungi play a major role in bioremediation owing to their robust morphology and diverse metabolic capacity. The review focuses on different fungal groups from a variety of habitats with their role in bioremediation of different toxic and recalcitrant compounds; persistent organic pollutants, textile dyes, effluents from textile, bleached kraft pulp, leather tanning industries, petroleum, polyaromatic hydrocarbons, pharmaceuticals and personal care products, and pesticides. Bioremediation of toxic organics by fungi is the most sustainable and green route for cleanup of contaminated sites and we discuss the multiple modes employed by fungi for detoxification of different toxic and recalcitrant compounds including prominent fungal enzymes viz., catalases, laccases, peroxidases and cyrochrome P450 monooxygeneses. We have also discussed the recent advances in enzyme engineering and genomics and research being carried out to trace the less understood bioremediation pathways.

The vast majority of the research on biological decolorization has been carried out on fungi and mainly on their ligninolytic enzymes, discovered to degrade azo dyes aerobically (Erkurt et al 2010).…”

Escherichia coli strain DH5α was successfully employed in the decolorization of commercial anthraquinone and azo dyes, belonging to the general classes of acid or basic dyes. The bacteria showed an aptitude to survive at different pH values on any dye solution tested, and a rapid decolorization was obtained under aerobic conditions for the whole collection of dyes. A deep investigation about the mode of action of E. coli was carried out to demonstrate that dye decolorization mainly occurred via three different pathways, specifically bacterial induced precipitation, cell wall adsorption, and metabolism, whose weight was correlated with the chemical nature of the dye. In the case of basic azo dyes, an unexpected fast decolorization was observed after just 2-h postinoculation under aerobic conditions, suggesting that metabolism was the main mechanism involved in basic azo dye degradation, as unequivocally demonstrated by mass spectrometric analysis. The reductive cleavage of the azo group by E. coli on basic azo dyes was also further demonstrated by the inhibition of decolorization occurring when glucose was added to the dye solution. Moreover, no residual toxicity was found in the E. coli-treated basic azo dye solutions by performing Daphnia magna acute toxicity assays. The results of the present study demonstrated that E. coli can be simply exploited for its natural metabolic pathways, without applying any recombinant technology. The high versatility and adaptability of this bacterium could encourage its involvement in industrial bioremediation of textile and leather dyeing wastewaters.
