Abstract

Research on the biodecolorization of Procion red dyes using B. cereus has been carried out. The ability of B. cereus in decolorization is analyzed qualitatively and quantitatively, where there is a qualitative decrease in the intensity of Procion red dyes after decolorization by B. cereus. Quantitatively based on the percent decolorization value calculated from the decrease in the absorbance value of Procion red at a wavelength of 560 nm. The percent decolorization level of Procion red by B. cereus is 86.89%. Determination of optimum conditions is done by four conditions in the form of incubation time, dye concentration, temperature and pH. The results of percent decolorization of Procion red by B. cereus at 24 hour incubation was 90.32%, at a concentration of 80 mg / L dye of 89.70%, 37oC temperature of 88.70%, and pH 7 of 89.66% . Determination of decolorization activity in the dyestuff dyestuff by B. cereus is done with percent decolorization which is calculated from the decrease in the absorbance value of the dyestuff dyestuff at wavelength 508 nm. The level of decolorization of Jumputan red dye waste by B. cereus was 87.41%. This shows that the bacteria are also able to decolorize the red dye waste. Qualitative analysis of decolorization by B. cereus was carried out using thin layer chromatography (TLC) and UV-Vis spectrophotometry. From the results of TLC and UV-Vis Spectrum showed degradation occurred in Procion red dyes and absorption of red dyes occurred.
