Bioremediation of Binary System of Reactive Red 120 Dye and Cr(III) Using Aspergillus tamari and Statistical Validation of Response
The efficiency of Aspergillus tamarii (isolated from sludge of a textile industry) was investigated to remediate the synthetic solutions of reactive red 120 (RR120) dye and chromium(III) separately. Also, parallel studies were conducted on the bioremediation of binary system of chromium(III) and RR1...

| Summary: | The efficiency of Aspergillus tamarii (isolated from sludge of a textile industry) was investigated to remediate the synthetic solutions of reactive red 120 (RR120) dye and chromium(III) separately. Also, parallel studies were conducted on the bioremediation of binary system of chromium(III) and RR120 dye in different ratios. The study was conducted to find the potential of the A. tamarii for removing chromium(III) and color from solutions containing only chromium or only RR120 dye or both and the effect of RR120 and chromium on the growth of the strain were observed. Maximum dye removal 81 mg/L was observed from 100 mg/L RR120 dye solution at pH 5 up to 50 hours. Maximum chromium removal 88.3 mg/L was observed from 100 mg/L chromium (III) solution at pH 5 up to 50 hours. In previous studies, A. tamarii was used as a bioremediator for removing different chromium complex dyes. The removal of chromium(III) and color were compared from solutions of synthetic mixtures and chromium complex dyes. The response of bioremediation study was validated using multiple regression analysis. |
