Abstract

Background: In the present study has been carried out to find the suitable bio degradation measures of textile dye by using biological agents. The wastewater containing dye was obtained from a textile factory situated in Thiruvananthapuram.
Materials and Methods : The study focused on three specific types of dyes: direct black, direct blue, and direct orange. Based on Microscopic, Macroscopic, Biochemical, Hydrolysis tests and selective plating upon comparing with Bergy’s Manual (9edition) the selected organism were identified as, sp, sp and sp. The isolates were then tested for their ability to degrade the dyes.
Result: In this study it was identified that sp possessed the higher dye degrading ability. This specific isolate is then carried out for 16SrRNA sequencing analysis and it was confirmed that the highest degraded organism (AZ2) was strain JW-22. The toxicity of the textile dyes determined using seed germination.
Conclusion: The isolated bacteria demonstrate the capability to remove color from commonly used textile dyes. In the future, these bacterial strains could serve as effective tools for bioremediation in treating various textile effluents, transforming toxic dyes into harmless, colorless products. The treated effluents could then be recycled for use within the textile industry.
