The potential of free cells of Pseudomonas aeruginosa on textile dye degradation.

The objective of the present work was to reduce chemical oxygen demand (COD), color of textile effluent containing dye Procion Blue 2G and recycle the treated effluent. To achieve this objective, the degradation potential of bacterial strain Pseudomonas aeruginosa was tested. In degradation, the 'clean' electro-oxidation (EO) process was combined with bio-treatment such that an electro-oxidation step was included between two bio-degradation treatments.
