Abstract
As known, naturally-occurring edible flora contained crucial compositions to human health (e.g., antioxidants). Prior studies revealed that decolorized metabolites (DM) of textile dyes might be used to enhance electron-transfer (ET) capabilities of dye decolorization and bioelectricity generation (DD&BG). Such ET stimulating phenomena were suspected to be associated with antioxidant characteristics. This study selected 6 edible flora to explore such relationship between antioxidant and dye-decolorizing characteristics. The finding indicated that DM of Gynura bicolor could show electron-shuttling capabilities to increase ET efficiency of DD&BG. Moreover, the dosage should exceed threshold level to trigger effective ET performance. Apparently, supplementation of sufficient DM of G. bicolor to azo dyes RBk5 significantly enhance efficiency of DD. Comparative assessment also suggested that chemical structure affected color removal efficiency, indicating optimal strategy for wastewater decolorization.
