Abstract

Highlights: Achromobacter xylosoxidans strain APZ used in our previous study was employed to decolorize and degrade the phthalocyanine dye. The agricultural residues were utilized for aiding RB38 decolorization. The strain degraded RB38 and resulted in desulfonation. Response surface estimation and canonical correlation analyzed the optimal parameters. Abstract: The degradation of a phthalocyanine dye, Reactive Blue 38 (RB38) was achieved by employing bacterium; Achromobacter xylosoxidans strain APZ from our previous study. RB38 decolorization by A. xylosoxidans strain APZ was performed by supplementing Bushnell-Haas medium (BHM) with different agricultural residues, individually. Amongst the different agricultural residues, the groundnut shell powder nourished the bacterial strain by supplementing them with considerable total organic carbon to nitrogen (TOC/N) ratio for degrading the RB38 dye. "One-factor-at-a-time" (OFAT) approach followed by response surface methodology (RSM) and canonical correlation analysis were employed to quantify the optimal parameters influencing the RB38 decolorization by A. xylosoxidans strain APZ. The canonical analysis quantified the optimal values and suggested that RB38 decolorization could be ameliorated when BHM is supplemented with 5.133 g/L groundnut shell powder at pH 7.35 and 34.64 °C. RB38 bio-degradation was catalyzed by the different oxido-reductases of A. xylosoxidans strain APZ, which led to the desulfonation. Conclusively, the results of the phytotoxicity assays confirmed the detoxified nature of the metabolites.
