“…The isolation of Providencia species has been previously reported from dye contaminated soils and known to degrade textile dye Red HE3B in consortium with Ps. aeuroginosa strain BCH (Phugare et al 2011a). Similarly, isolation, screening, and identifi cation of textile dye Solvent Red 5B degrading P. staurti strain Ebt SPG has been reported (Kadam et al 2013).…”

“…The application of Comet assay is considered to be a rapid, sensitive, inexpensive and simple method for detecting DNA damage on root meristem of individual cells of A. cepa (Chakraborty et al 2009, Phugare et al 2011a). The results of Comet assay demonstrated that the root meristem of A. cepa bulbs showed genetic damage in the presence of textile effl uent as the chromosomal material integrity was disturbed as well as it was oozing out in the form of bulging in nuclear membrane showing comet like structure (Fig.…”

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.

“…Several bacteria have been shown to degrade azo dyes (Saratale et al 2011), and it has been documented that decolorization occurs via bacterial azoreductases, followed by the aerobic mineralization of colorless amines (Pandey et al 2007; Van der Zee and Villaverde 2005). Generally, this two-step process may require a bacterial consortium to successfully complete the azo dye biodegradation task, but the reproducibility profile is often low undermining potential industrial applications (Phugare et al 2011). The most extensively studied bacterial species belong to the genus Pseudomonas (e.g., P. luteola) Chen and Lin 2007).…”

Escherichia coli strain DH5α was successfully employed in the decolorization of commercial anthraquinone and azo dyes, belonging to the general classes of acid or basic dyes. The bacteria showed an aptitude to survive at different pH values on any dye solution tested, and a rapid decolorization was obtained under aerobic conditions for the whole collection of dyes. A deep investigation about the mode of action of E. coli was carried out to demonstrate that dye decolorization mainly occurred via three different pathways, specifically bacterial induced precipitation, cell wall adsorption, and metabolism, whose weight was correlated with the chemical nature of the dye. In the case of basic azo dyes, an unexpected fast decolorization was observed after just 2-h postinoculation under aerobic conditions, suggesting that metabolism was the main mechanism involved in basic azo dye degradation, as unequivocally demonstrated by mass spectrometric analysis. The reductive cleavage of the azo group by E. coli on basic azo dyes was also further demonstrated by the inhibition of decolorization occurring when glucose was added to the dye solution. Moreover, no residual toxicity was found in the E. coli-treated basic azo dye solutions by performing Daphnia magna acute toxicity assays. The results of the present study demonstrated that E. coli can be simply exploited for its natural metabolic pathways, without applying any recombinant technology. The high versatility and adaptability of this bacterium could encourage its involvement in industrial bioremediation of textile and leather dyeing wastewaters.
