A kinetic study of textile dyeing wastewater degradation by Penicillium chrysogenum

Abstract

The potential of Penicillium chrysogenum to decolorize azo dyes and a real industrial textile wastewater was studied. P. chrysogenum was able to decolorize and degrade three azo dyes (200 mg L(-1)), either independently or in a mixture of them, using glucose as a carbon source. A kinetic model for degradation was developed and it allowed predicting the degradation kinetics of the mixture of the three azo dyes. In addition, P. chrysogenum was able to decolorize real industrial wastewater. The kinetic model proposed was also able to predict the decolorization of the real wastewater. The calibration of the proposed model makes it a useful tool for future wastewater facilities' design and for practical applications.

Requalification of a Brazilian Trichoderma Collection and Screening of Its Capability to Decolourise Real Textile Effluent

“…Textile industries waste large water quantities that in some cases return to environment as untreated or incorrectly treated effluents [1]. Due to the presence of non-fixed dyes during the dyeing process, these wastewaters are highly coloured [2,3].…”

“…In recent years, relevant methods based on biological textile effluents degradation have been developed using bacteria and fungi in aerobic and anaerobic processes [1,2,4,5,6,7,8,9,10]. A recent review on current technologies for biological treatment of textile wastewater discusses in deep these bioprocesses [11].…”

Preparation of Quaternary Ammonium Salt-Modified Chitosan Microspheres and Their Application in Dyeing Wastewater Treatment

“…In recent years, with the increasing discharge of dyeing wastewater and causing more pollution to water resources, dyeing wastewater has attracted great attention due to its degradation resistance, strong colority, and high toxicity. − Various methods based on biodegradation, adsorption, − oxidation, coagulation, and other approaches have been widely utilized for dyeing wastewater treatment. Adsorption presents obvious advantages over other approaches because of the simple design, low cost, and high efficiency .…”

Detoxification of a triphenylmethane textile colorant using acclimated cells of Bacillus mannanilyticus strain AVS

“…The conventional physicochemical treatments decolorize the textile effluent, but the addition of chemicals will increase the toxicity in the final treated discharge . The bioremediation strategy involving enzymes and microbial cells have gained pervasive attention and the use of indigenous bacterial strains are more advantageous than fungal strains . The bacterial cells attack the dye molecule and mineralize remarkably in association with various inducible oxidoreductases .…”
