Presence of Aeromonas punctatain polyurethane foam and Agar-Agar matrices was confirmed by scanning electron microscopy after immobilization process. Free cells of A. punctatawas able to show 100% degradation of Reactive Black 5 dye upto 100 ppm of dye concentration, whereas both PUF and Agar-Agar immobilized cells of A. punctatashowed 100% degradation of Reactive Black 5 dye upto 200 ppm of dye concentration. On repeated use of PUF and Agar-Agar immobilized cells of A. punctata100% degradation of Reactive Black 5 dye was recorded upto 10 cycles at 200 ppm of dye concentration. On continuous treatment, PUF immobilized cells of A. punctatashowed 100% degradation of Reactive Black 5 dye upto 1600 ppm of dye concentration at 10 ml/hr flow rate and Agar-Agar immobilized cells of A. punctatacould show 100% degradation of Reactive Black 5 dye upto 1800 ppm of dye concentration at 10 ml/hr flow rate.
