Efficacy of Rhodococcus rhodochrous in Microbial Degradation of Toludine Dye
Author(s): Shah MShah M
An efficacy of Rhodococcus rhodochrous for the treatment of toludine red was investigated by using dye as sole carbon source. Optimization of various parameters such as pH, temperature, NaCl percentage (w/v) and dye concentration was studied by using one factor at a time method. Rhodococcus rhodochrous was capable of decolorizing Toluidine Red at a pH and temperature range of 6.5-9.5 and 25°C-40°C respectively and the best decolourization was achieved at 25ppm dye concentration, pH 6.5, temperature 35°C and 5% (w/v) NaCl. Optimized UV-Vis and HPLC analysis proposed that decolourization was occurred under biodegradation mechanism rather than bio sorption. GC/MS analysis was carried out to identify degradation products. Final compounds formed from dye degradation appeared at m/z 193 and m/z 77 which were identified as 2-(2-carboxy vinyl) benzoic acid and Benzene respectiv.. View More»
