| Dissertation note | Azo dyes are synthetic organic compounds widely used in the textile, paper, cosmetics, pharmaceutical and food industries. It consist of one or more azo bonds (-N=N-) associated with one or more aromatic systems. Studies indicate that these dyes are toxic, harmful to the environment and form carcinogenic and/or mutagenic aromatic amines. These are not readily biodegradable in textile effluent treatment. To decolorize and degrade the textile industry dye effluents by treatment with microorganism Candida tropicalis (yeast) to an extent to make it least harmful to the water habitat and also to make fit for irrigation purposes. The influencing parameters that affect the percentage of decolorization rates are optimized in still culture fermentation. Spectrophotometric analysis method was used to estimate decolorization of textile effluent at its?max 390 nm. The optimal values of parameters such as effluent to water ratio, fermentation time and pH and carbon to nitrogen ratio are found to be 1:5, 72 hours, 6.0and 1:1.72 respectively. The concentration of ionic saltof CaCl2 was also optimized for maximum decolorizationand optimized concentration was 0.15% for Candida tropicalisrespectively. The decolorization of effluent was carried out on large scale in a flask of 2.5 L by applying the predetermined optimum levels. In this case the maximum percent of decolorization of the effluent was found to 80.34% with Candida tropicalis. |
