“…Bioadsorption in present study has been linked to electrostatic pull between negative charged dyes and positively charged cell wall components of fungi (Aksu and Tezer 2000 ). Earlier, published reports on azo dye degradation by P. ostreatus are in accordance to our results of biodegradation of textile azo dyes (Andrade et al 2013 ; Kalmış et al 2007 ; Yesilada et al 2003 ).…”

BackgroundTotal three Pleurotus species (P. ostreatus, P. sapidus, P. florida) was compared for ligninolytic enzyme production grown with Coralene Golden Yellow, Coralene Navy Blue and Coralene Dark Red azo dyes in liquid medium under shaking condition.ResultsThe biodegradation competency varied from species to species and it was found that P. ostreatus, P. sapidus and P. florida to 20 ppm dye concentration shows 88, 92 and 98 % decolorization, respectively for all three dyes. Production pattern of laccase, manganese dependent peroxidase and lignin peroxidase were studied during the growth of the organisms for 10 days. Laccase was found to be the major extracellular ligninolytic enzyme produced by fungus with negligible detection of lignin peroxidases. In all concentration of three dye studied, maximum laccase activity was observed on day 8, for 20 mg/l of dye laccase specific activity was 1–1.58 U/mg in P. ostreatus, 0.5–0.78 U/mg in P. sapidus and 1–1.92 U/mg in P. florida. Different factors (dye concentration, pH, protein and sugar estimation) influencing the ability of Pleurotus species to degrade dyes is documented and degradation was attributed to microbial action irrespective of pH change. HPTLC analysis of samples indicated degradation of dyes into intermediate products.ConclusionLevel of ligninolytic enzymes is playing a major role in degradation of dye, which is dependent on time of incubation and species of fungi.

“…The systems with P. ostreatus and T. villosa responded positively (p < 0.05) to the decolorization, according to the formulation of the synthetic effluent and the contact time (figure 1). P. ostreatus (figure 1a) (0.05 g L -1 ) in the presence of the saccharose and absence of urea Andrade et al (2013).…”

Reactive dyes are found in the final effluents of the textile industry and cannot be removed by conventional treatment processes. The use of basidiomycetes appears to be an effective strategy to degrade dye molecules. In this paper, the parameters that favor decolorization of diazo dye were assessed using basidiomycetes immobilized in Luffa cylindrica. Different concentrations of saccharose and urea were assessed, in addition to the introduction of an enriched synthetic effluent. Results showed that the best decolorization occurred at the highest concentration of saccharose and the lowest of urea. It was observed a high biosorptive capacity of the solid support, which decreased when the effluent was enriched with saccharose and urea due to consequent increase in microbial activity. Using the enriched effluent, Pleurotus ostreatus decolorized about 70% within 48 hours, and Trametes villosa decolorized 58% after 240 hours. Peniophora cinerea did not respond to the conditions tested.

“…Valores significativos de biomassa e componentes celulares podem ser obtidos por otimização de condições de cultivo, por isso em planejamento de sistemas de tratamento é importante estimular a produção das enzimas ligninolíticas, adicionando compostos considerados indutores e/ou estimuladores ao cultivo dos fungos. Uma vez que estudos relatam que a presença de co-substratos, como fontes de carbono e nitrogênio, favorece a descoloração e ainda estimula a produção enzimática (ALI, 2010;ANDRADE et al, 2013;FUKUDA et al, 2009;GAHLOUT et al, 2013;LEVIN et al, 2010;SARAYU;SANDHYA, 2012). Nesse contexto, uma variedade de substratos é avaliada como fonte de carbono e nitrogênio, visando a minimização dos custos dos processos, como por exemplo, amido, glicerol, farelo de arroz e de trigo, licor de maceração de milho, extrato de levedura, glúten de milho, oxalato de amônio, entre outros, variando os melhores substratos e suas concentrações, de acordo com os espécimes estudados.…”
