| Abstract: | This study presents batch degradation of Reactive Black
5 (RB5) and Reactive Red 120 (RR120) dyes using free cells of Aeromonas
punctata and Pseudomonas aeruginosa, resulting 100% degradation up
to 100 ppm and 150 ppm of respective dye. Immobilized cells showed 100%
degradation of RB5 dye (up to 150 ppm) and RR120 dye (up to 200 ppm). On
repeated use of immobilized beads, both A. punctata and P. aeruginosa
showed 100% degradation of respective dye (at 150 ppm conc.) up to 10
cycles. During continuous degradation, degradation efficiencies of both
cultures decreased with increase in dye concentration and flow rate.
Degradation efficiency of P. aeruginosa was better than A. punctata with
different flow rate and dye concentration. |
