STUDY ON DECOLORIZATION OF DYE STUFF (AZO DYE-CONGO RED) BY USING BACTERIAL CONSORTIA
Objective: The present study is focused on the screening, isolation of effective bacterial microorganisms for the decolorization of textile effluent and evaluation of the performance of the process also optimization of parameters for enhanced decolorization.
Methods: The isolation was carried out by serial dilution method and the decolorization was carried out in the batch reactor.
Results: The effective bacteria isolated from the textile were Proteus mirabilis, Staphylococcus aureus, Bacillus subtilus, Bacillus funiculus and Pseudomonas fluorescens have been characterized by biochemical assay also with Scanning Electron Microscopy (SEM).
Conclusion: The decolorization process using bacterial consortia for various dye yields 95% decolorization. The process was simple, cost-effective and eco-friendly. The parameters such as temperature, pH, nutrients, time had the greater potential for the effective growth of microorganisms were optimized and can be applied to the diverse textile treatment applications.
