Degradation and detoxification of three textile Azo dyes by mixed fungal cultures from semi-arid region of Brazilian Northeast

Abstract

The aim of this work was to study the degradation and detoxification of three textile azo dyes (Reactive Red 198, Reactive Red 141 and Reactive Blue 214)

Decolorization of synthetic brilliant green carpet industry dye through fungal co-culture technology

“…Because of the synergistic interaction of two strains (Penicillium oxalicum and Pleurotus ostreatus), enhanced production of lignocellulolytic enzymes was achieved under co-cultivation condition (Dwivedi et al, 2011). In the present decade; few studies concentrated on decolorization by mixed fungal cultures and represented superior dye decolorization than single cultures (Ramalingam et al, 2010;Nascimento et al, 2011;Asgher et al, 2012). In a recent study, a defined consortium of Aspergillus ochraceus and Pseudomonas sp.…”

Textile Dyes Degradation: A Microbial Approach for Biodegradation of Pollutants

“…This is mainly due to the fact that many dyes are manufactured from known carcinogens, such as benzidine, naphthalene and other aromatic compounds (Nascimento et al 2011). Many workers have studied the effects of dyes on microorganisms.…”

Textile azo dye degradation by Candida rugosa INCQS 71011 isolated from a non-impacted area in Semi-Arid Region of Brazilian Northeast

“…The yeast strain CE-9 was isolated from a mixed fungal culture do Nascimento et al 6637 collected from Caldeirão Escuridão (CE), a natural water reservoir situated in the surroundings of the Serra da Capivara National Park, at an altitude of 423 m (xUTM -769341, yUTM -9022784 (Nascimento et al, 2011 For routine work at laboratory scale, the selected yeasts were maintained on yeast extract-malt extract agar (YMA) slants at 4°C and subcultured at 15 day regular intervals.…”

“…From the most efficient mixed fungal culture, Caldeirão Escuridão (CE), a yeast strain (CE-9) was isolated (Nascimento et al, 2011). Therefore, the aim of the present work was to identify by phenotypic and molecular methods the yeast CE-9 as well as to test its capacity to degrade three textile azo dyes.…”
