| Résumé : |
The isolate P6, an indigenous Shewanella sp., was able to decolorise 90% of CI Acid Blue 113 in just 30 min of incubation under anoxic conditions. The decolorisation potential of cells was not significantly affected even in the presence of 2% (w/v) sodium chloride and 8% (w/v) sodium sulphate. Mass spectrometric analysis detected the formation of aniline sodium salt, 1,4-diaminonaphthalene, 5-amino-8-(phenylamino)-naphthalene-1-sulphonic acid sodium salt and 8-(phenylamino)-naphthalene-1-sulphonic acid sodium salt. Further, cells of P6 decolorised the raw effluent collected from the equalisation tank of a textile industry wastewater treatment plant. The water-soluble dyes/intermediates present in the sludge, generated after chemical flocculation of raw effluent, were transformed by P6 cells within 24 h of incubation under anoxic conditions. Thus, isolate P6 has a potential application in the biological treatment of liquid and solid waste of textile processing plants because of its efficient decolorisation and transformation properties. |
