  abstract = {{T}his work aims to study the by-products generated by the anaerobic degradation process of synthetic wastewater containing indigo dye. {T}hese by-products were analysed and identified by both high performance liquid chromatography ({HPLC}) and nuclear magnetic resonance ({H}-1 {NMR}). {HPLC} results showed the dependence of the by-products to the operating conditions. {T}he obtained {HPLC} chromatogram at the end of the experiments ({R}un 1) reveals different fractions, with at least eight distinguishable by-products. {I}ncreasing the hydraulic retention time from 1 to 5days ({R}un 5) which corresponding to the start up of the bioreactor caused a significant change of the obtained {HPLC} chromatogram, with the decrease of the number of these by-products to only 3 ones. {H}-1 {NMR} analysis was realised with three representative fractions. {T}he results showed that hypothetical structure of the by-products corresponding to aromatic cycles 1,2-disubstituted and possessing an axial symmetry similar to the phthalate groups.},
