dc.description.abstractThe potential of an organism isolated from a mixture of azo dyes to decolourize textile wastewater was investigated. The organism identified by 16S rDNA as a strain of Providencia rettgeri was able to remove 94 ± 0.56% of the colour in a dyehouse effluent within 24 h in batch experiments. P. rettgeri strain ODO was able to use the effluent as sole carbon and nitrogen source. The optimum pH and temperature for colour removal ranged between 7–8 and 30–35 °C, respectively. Analysis of the data showed that the decolourization process exhibited first-order kinetics with respect to the colour intensity and biomass concentration. The rate constant k=5.6 10 3 L/gDCMh at 37 °C. The specific growth rate, μ, of the organism was 0.013 h 1 while the mean doubling time was 52.9 h. The results indicated that P. rettgeri strain ODO has the potential for colour removal from textile effluent.en_US
