Abstract

Disposal of dyes into the environment causes serious damage and they may be toxic to some aquatic organisms due to their breakdown products. The coloring pigments in the effluent may cause serious effects to living organism due to the presence of aromatic chemicals. Biosorption and bioaugmentation are effective biological process for the removal of pollutants with the help of microorganisms. In the present study an attempt was made to examine the potential of Saccharomyces cerevisiae, decolorization of Congo red dye. The influence of different variables namely concentration of dye solution, time, dosage and initial pH on maximum color removal were performed. The UV Spectrum shows the maximum wavelength of 496.93 nm for congo red solution. At room temperature, the maximum decolorization of 90.7% was achieved for 18 h using dye solution concentration of 40 ppm. The suitable initial pH and dosage for removal of color was found to be 4 and 0.1 g with maximum color removal. Finally, the screening of carbon source for the cultivation of yeast cells on decolorization was performed. Based on the previous study, response surface design of experiments was employed in order to maximize the removal of color. The polynomial regression equation was obtained from regression analysis. FTIR spectra was performed in order to conform the biosorption of dye effluent on to viable yeast cells and compared.
