This feasibility study used indigenous microbes to implement assessment upon capabilites of dye decolorization with supplementation of decolorized metabolites (DM) of Hylocereus polyrhizus. As indicated, ca. 5% DM of Hylocereus polyrhizus could clearly exhibit reversible redox peak potentials via cyclic voltammetric analysis, revealing its significant capability as electron-shuttling mediators. Compared to DM-supplemented decolorization, the ranking of dye-decolorizing capabilities of bacteria was Shewanella putrefaciens WLP72> Enterobacter cancerogenus BYm30> Aeromonas hydrophila NIU01~ A. hydrophila YTl1> Klebsiella pneumoniae ZMd31. The ranking of biodegradability of azo dyes was RB160 > RBk5 > DY86˜=RG19 > RR141. Evidently, the presence of DM significantly stimulated bacterial decolorization performance of WLP72, BYm30, ZMd31. However, possibly due to inhibitory characteristics of DM to A. hydrophila, its dye decolorization was delayed. That is, using DM to enhance dye decolorization, biodecolorizers should be acclimated in such envionments for effective expression. The findings also pointed out that supplementation of DM to YTl1, WLP72 at ca. 10~15 % for decolorization of RR141 could effectively increase dye-decolorizing efficiency ca. 2.33~2.88 fold. Such DM augmentation inevitably could autocatalytically stimulate electron transfer capabilities for optimal wastewater decolorization with sustainable development.
