@article{P. Ganesh_2011, title={Decolourization of Textile Azo Dyes by using Bacteria Isolated from Textile Dye Effluent}, volume={3}, url={https://www.updatepublishing.com/journal/index.php/jebt/article/view/176}, abstractNote={<p class="MsoNormal" style="text-align: justify; margin: 6pt 0in 0pt;"><span style="font-family: ";Arial Narrow";,";sans-serif";; font-size: 10pt;">The present study was carried out to isolate dye decolourizing bacteria and to study the dye decolourizing ability.<span style="mso-spacerun: yes;">  </span>Different bacterial isolate such as, <em style="mso-bidi-font-style: normal;">Bacillus </em>sp.<em style="mso-bidi-font-style: normal;">, Escherichia coli </em>and<em style="mso-bidi-font-style: normal;"> Pseudomonas fluorescens </em>were isolated from textile dye effluent sample and used for the decolourization study. It was noticed that there was a decrease in the OD in all the three species of all the five dyes as the incubation period increased. <em style="mso-bidi-font-style: normal;">Pseudomonas fluorescens</em> was more effective followed by <em style="mso-bidi-font-style: normal;">Bacillus, </em>and <em style="mso-bidi-font-style: normal;">Escherichia coli.</em> It was found that all the isolated bacteria were efficient decolourizers of Orange 3R.<span style="mso-spacerun: yes;">  </span>The decolourization of dye amounted to 59, 77, 79 respectively within 16 days.<span style="mso-spacerun: yes;">  </span>Yellow GR was recalcitrant to decolourization, the O.D. value from an initial value of 0.6912 was reduced only to 0.303 and from 0.746 to 0.218, 1.236, to 1.33 by <em style="mso-bidi-font-style: normal;">Pseudomonas fluorescens, Bacillus </em>sp.<em style="mso-bidi-font-style: normal;"> </em>and<em style="mso-bidi-font-style: normal;"> Escherichia coli </em>respectively. Percentage decolourization was 43%, 15%, 90% respectively. The percentage of decolourization of Orange GR is slightly higher than Blue 3R and the percentage decolourization of Black RL is similar to T Blue.</span></p>}, number={8}, journal={Journal of Ecobiotechnology}, author={P.
