Patel, Darshna K. published the artcileEnzyme mediated bacterial biotransformation and reduction in toxicity of 1:2 chromium complex AB193 and AB194 dyes, Computed Properties of 116-63-2, the publication is Journal of the Taiwan Institute of Chemical Engineers (2017), 1-9, database is CAplus.
A bacterial consortium was developed and applied for the treatment of 1:2 chromium complex azo dyes. Fed batch process was studied with optimized conditions for the decolorization of AB193 and AB194 up to 1100-1400 mg L-1 of cumulative dye concentration without further nutrient addition Fed batch adapted consortium showed 39 and 42% enhanced decolorization for AB193 and AB194, resp. as compared to unadapted consortium. After bio-degradation of the dyes, chromium was not detected in the medium supernatant where as chromium was found sorbed on bacterial cell biomass. During the decolorization process laccase, lignin peroxidase, tyrosinase, azoreductase and NADH-DCIP reductase enzymes were found to be induced. HPLC and FTIR anal. data confirmed the biodegradation of both the dyes. Biodegradation pathways were proposed on the basis of H1 NMR and GC-HRMS anal. along with role of induced enzymic system in the degradation process. 45-66% stimulation in growth was observed for Sorghum bicolor and Cicer aeriatinum when biodegradation products of both the dyes were used. Reduction in toxicity on S. aureus and P. aeruginosa was recorded in the range of 58-100% and 43-100%, resp.
