“…F022 (Hadibarata et al 2012b), Trametes sp. SQ01 (Yang et al 2009) and F. fomentarius (Neifar et al 2010). Many azo dyes were not substrates of laccases and their decolorization depended on some small redox mediators (Camarero et al 2005).…”

CotA protein is a component of the endospore coat of Bacillus subtilis and it exhibits the activities of laccase. CotA protein is known as CotA laccase. A CotA laccase gene from B. subtilis WD23 was cloned and expressed in Escherichia coli. The expressed CotA laccase was observed in an active form. The molecular weight of CotA laccase was estimated to be 67.5 kDa. Optimal laccase activity was detected at pH 7.2 and 45°C with syringaldazine as substrate. The half-life of the laccase was 1.5 h at 80°C at the optimum pH. Half of the laccase activity was lost after 8 h at 45°C and pH 9.0. The CotA laccase exhibited high tolerance to acetone, petroleum ether, ethyl acetate and chloroform, like spore laccase. Purified CotA laccase was activated 157 % by Cu 2+ and remained stable to Fe 2+ . The purified CotA laccase could decolorize 87 % of Remazol Brilliant Blue R (RBBR) and 81 % of Congo Red in 6 h in absence of any mediator.

“…Resistance of Congo red to decolorization by laccase from Trametes sp. SQ01, an enzyme that efficiently decolorizes various azo-, triphenylmethane-, and anthraquinone dyes has been known (Yang et al, 2009). After 24 h treatment, only 47% of the Congo red was decolorized by the pure laccase of Trametes sp.…”

“…Biodegradation of triphenylmethane dyes has been studied by bacteria, actinomycetes, yeasts, and fungi. In the specific case of WRF, degradation by laccases has only been reported [48]. Currently the degradation pattern of the dyes by the fungi is being studied as well as the development of an effluents treatment system based in their metabolism.…”

This study analyzed some alternatives to the valorization of agricultural residues considering its use in the treatment of colored effluents. The acid-base behavior of the banana peel surface was thus determined in order to establish the feasibility of its use as a bioadsorbent for dyes. The adsorption capacity of Acid Black 1 was evaluated, through the equilibrium isotherm and the kinetics of this uptake process was also analyzed. Additionally, banana peel was used as substrate-support to evaluate the growth of Inonotus sp SP2, Stereum hirsutum RU 104 and Pleurotus eryngii IJFM 169 and their ligninolytic enzymes production. The decolourization ability of strain fungi was moreover screened. The concentration of functional basic groups in the banana peel surface was determined in 5.5 mmol g -1 as six and a half times higher than acid groups, while the lowest value of the maximum adsorption capacity of Acid Black 1 was 250 mg g -1 . The adsorption kinetics of this dye was suitably represented by a pseudo second order model, obtaining correlation coefficients greater than 0.98. Additionally, the banana peel was demonstrated to be a source of carbon available for growth of the fungi studied. Reducing sugars supplied for banana peel were abruptly consumed up to the 5th day by S. hirsutum and Inonotus sp, while a slower consumption was observed in the case of P. eryngii. Manganese Peroxidase was produced by the three fungal strains, Inonotus sp. additionally produces Laccase and Aryl-alcohol oxidase.Screening assays showed that all of the dyes were decolorized, resulting in efficiencies between 50 and 99% by the three strains, with the exception of Basic Violet 4. Acid Black 1 was decolorized efficiently by Inonotus sp and S. hirsutum. In conclusion, banana peel is a promising material for development of an integral bioremediation strategy for wastewater containing hazardous compounds.
