Overview

The study demonstrates effective dye detoxification using Aeromonas hydrophila in sodium alginate beads, indicating a promising method for textile wastewater treatment.

Key Points

  • To evaluate the decolorization ability of immobilized Aeromonas hydrophila for reactive blue 222 dye in wastewater.
  • Immobilization of bacteria on sodium alginate beads
  • Application of Response Surface Methodology for optimization
  • Analysis using Ultraviolet-visible spectroscopy and Gas Chromatography-Mass Spectrometry
  • Achieved up to 98.54% decolorization efficiency under optimal conditions
  • Confirmed dye degradation through advanced spectroscopy techniques
  • Indicated formation of phenolic compounds and other benign metabolites for detoxification
