“…SDS and Ps. aeuroginosa strain BCH showed the inductive pattern of oxidoreductive enzymes laccase, azo reductase and NADH-DCIP in the degradation of textile effl uent (Phugare et al 2011b). It has also been reported that fungal lignin peroxidases show higher oxidative degradation potential towards azo dyes (Parshetti et al 2007, Pasti-Grigsby et al 1992).…”

“…However, untreated textile effl uent showed very high values for genotoxic parameters such as 118 μm tail length, 10 of the tail moment and 14% DNA in tail suggesting its toxic nature. Textile dyes such as Direct red 73 and effl uent are known to possess strong genotoxic effect on A. cepa DNA in root meristems , Phugare et al 2011b.…”

Abstract:In the present study, the enrichment and isolation of textile effl uent decolorizing bacteria were carried out in wheat bran (WB) medium. The isolated bacterium Providencia rettgeri strain HSL1 was then tested for decolorization of textile effl uent in consortium with a dyestuff degrading fungus Aspergillus ochraceus NCIM 1146. Decolorization study suggests that A. ochraceus NCIM 1146 and P. rettgeri strain HSL1 alone re moves only 6 and 32% of textile effl uent American Dye Manufacturing Institute respectively in 30 h at 30 ±0.2°C of microaerophilic incubation, while the fungal-bacterial consortium does 92% ADMI removal within the same time period. The fungal-bacterial consortium exhibited enhanced decolorization rate due to the induction in activities of catalytic enzymes laccase (196%), lignin peroxidase (77%), azoreductase (80%) and NADH-DCIP reductase (84%). The HPLC analysis confi rmed the biodegradation of textile effl uent into various metabolites. Detoxifi cation studies of textile effl uent before and after treatment with fungal-bacterial consortium revealed reduced toxicity of degradation metabolites. The effi cient degradation and detoxifi cation by fungal-bacterial consortium pre-grown in agricultural based medium thus suggest a promising approach in designing low-cost treatment technologies for textile effl uent.

“…However, the heterogeneity of the composition of products used in dyeing (dyes, salts, additives, detergents and surfactants) makes it extremely difficult to achieve satisfactory wastewater quality levels, imposed by the international environmental standards. Conventional physical and chemical techniques of treatment such as activated carbon, membrane filtration and application of ozone Recently, many attempts have been made to obtain higher wastewater quality by replacing conventional methods currently applied (physical or chemical) with biological treatments which are more effective and less expensive (Dogruel et al 2006; Lofrano et al 2013; Phugare et al 2011). That is why an increasing number of textile industries through the world adopted biological treatment of wastewaters before the discharge in the environment.…”

Textile industry is considered as one of the important factors of the economic growth in Tunisia. However, this prominent role has certainly some drawbacks mainly represented by the huge amounts of textile wastewaters generated that become a real menace to nature. Many previous studies showed the purifying potential of some activated sludge and bacteria (Pseudomonas putida) to decolourize textile effluents. However, in many cases, decolourization of wastewaters is not necessary associated with detoxification, generating a real risk for the ecosystem in general. We evaluated in this work the induced toxicity of a textile effluent before and after its treatment with activated sludge followed by P. putida, using a battery of biotests. This study proved the detoxifying power of the activated sludge according to most of ecotoxicity tests. The treatment with P. putida did not improve the quality of the effluent; on the contrary, it could increase its toxicity. Daphnia magna and Raphidocelis subcapitata appear to be the most sensitive organisms in assessing eventual toxicity caused by this kind of wastewaters.
