“…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]. Some extremophilic fungi like Penicillium pinophilum isolated from Himalayan region was demonstrated to produce laccase at low temperatures [104].…”

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.

“…In this case, whole set of different oligomeric forms can be obtained: for many individual enzymes and enzyme mixtures. It is also possible to construct nonconventional protein: protein complex using by employing a micellar matrix for example a compact non-covalent chymotrypsin dimer or a stable [dissociating in water only in the presence of 8M urea] non-covalent complex of chymotrypsin with peroxidase [30].…”

Enzymes in aqueous environment usually deal with purified enzyme preparations isolated from living matter which does not mimic real catalytic properties in vivo. Interaction of enzymes in nature takes place with different surfaces composed from lipid membranes or they get incorporated into biomembranes. Although Water is not a dominating component in the cytoplasm but plays a structural role by participating in the formation of biocatalytic complexes like glycoproteins. Water is needed to keep biocatalyst in active confirmation and hence plays very crucial role in biocatalytic reactions, activity and stability so that it can be used for various applications. This review focuses on composition, preparation properties and parameters which influence enzymes in reverse micelles and application of micellar enzymology to study protein chemistry, shifting equilibrium of various reactions, to recover various products by partition chromatography and bioremediation of chlorophenolic environmental pollutants.

“…Phenol is present in effluents from major chemical and pharmaceutical industries such as petrochemical industries, petroleum refineries, coal gasification operations, liquefaction process, resin manufacturing industries, dye synthesis units, pulp and paper mills and pharmaceutical industries [1], total phenol concentration being in range 300 -400 mg/l [2,3]. It is a highly corrosive and nerve poisoning agent.…”

“…There are reports about ability to degrade cyclic compounds from cooking industry wastewater by 87% (from 313 mg/l) in six days, from olive mill waste waters by 89% (from 400 mg/l) in five days [2,3]. However, there is no comprehensive study about optimal conditions of phenol elimination from pharmaceutical wastewater and their quantitative effect degradation rate.…”

Phenol is a major contaminant in the industrial water effluent, including pharmaceutical wastewaters. Although several physic-chemical methods for removal of phenol exist, they are of high cost, low efficiency, and generate toxic byproducts. Thus, there is a need to develop technologies for biological removal of phenol from wastewater. In this study, the degradation of phenol in pharmaceutical wastewater by monoculture of white-rot fungi was studied. The degradation rate of total phenol in batch flasks by four fungal monocultures of Trametes versicolor, Phanerochaete chrysosporium, Gloeophyllum trabeum and Irpex lacteus in synthetic medium was compared. The results showed that white-rot fungus T.Versicolor was the most effective of the species. Further selection tests of optimal conditions of biomass concentration, pH and temperature were done, indicating that optimal conditions of degradation are at pH 5-6, temperature 25 o C, and biomass inoculum 10% (v/v). Under optimal conditions, total phenol was reduced by 93%, concentration of total phenol decreasing from 420±12 mg/l to 29±1 mg/l in seven days, with T.Versicolor specie. This study suggested that biological treatment with fungi may effectively be used as a pre-treatment stage for removal of phenol before polishing wastewater with conventional biological methods.
