Abstract

This study is to inspect the biodecolorization capabilities of indigenous strains to azo dyes (RR198, RR141, RBk5, RBu160, RBu171, DY86, RY84 and RG19). Shewanella sp. WLP72 isolated under selection pressure of decolorization of RBu160 upon gut microbial consortia of Babylonia areolate showed the optimal color removal capability. Due to this, WLP 72 had the highest capability to decolorize RBu160. Apparently, conditions of isolation of model dye(s) would affect dye-decolorizing capabilities of strains to be expressed. Moreover, the chemical structure effect of azo dyes would have a significant impact on decolorization efficiency as indicated through specific decolorization rate (SDR) of azo dyes by WLP72. The presence of electron-withdrawing groups (i.e., -SO₃^-) as the substituents at ortho- or para to azo bond would enhance decolorization efficiency. However, since the ortho substituent caused steric hindrance near azo linkage(s), azo dyes with para substituent could be more favorable than those with ortho substituent for decolorization. This study suggested that both the electronic characteristics of substituents in azo dyes and the positions of substituents related to azo bond on the aromatic ring all significantly affected the efficiency of biodecolorization of azo dyes.
