摘要：Bioremediation of textiles wastewater contaminated with dyes has been widelydescribed since their cost/efficiency ratios are lower than other physico-chemicalprocesses. In the present study, effluent samples were collected from textile industrieslocated in Settat city in Morocco, and were used for the isolation of bacterial strains thatare able to decolorize the textile dye Methyl Orange. Physico-chemical properties of theeffluent samples were analyzed and five bacterial strains S3, S4, S6, S7 and S8, capableof decolorizing Methyl Orange were screened and isolated. They showed more than90% of decolorization activity at 37°C and at neutral pH. UV-Visible absorption spectrabefore and after decolorization showed significant change in the positions of peaks,when compared to control dye spectrum, indicating that decolorization was due tobiodegradation.
