Abstract EN
A potential bacterial strain GSM2, capable of degrading an azo dye Reactive Violet 5 as a sole source of carbon, was isolated from textile mill effluent from Solapur, India.
The 16S rDNA sequence and phenotypic characteristics indicated an isolated organism as Paracoccus sp.
GSM2.
This strain exhibited complete decolorization of Reactive Violet 5 (100 mg/L) within 16 h, while maximally it could decolorize 800 mg/L of dye within 38 h with 73% decolorization under static condition.
For color removal, the most suitable pH and temperature were pH 6.0–9.0 and 25–40°C, respectively.
The isolate was able to decolorize more than 70% of five structurally different azo dyes within 38 h.
The isolate is salt tolerant as it can bring out more than 90% decolorization up to a salt concentration of 2% (w/v).
UV-Visible absorption spectra before and after decolorization suggested that decolorization was due to biodegradation and was further confirmed by FT-IR spectroscopy.
Overall results indicate the effectiveness of the strain GSM2 explored for the treatment of textile industry effluents containing various azo dyes.
To our knowledge, this could be the first report on biodegradation of Reactive Violet 5 by Paracoccus sp.
GSM2.
