Abstract

For the purpose of processing waste water discharged from dye-synthesizing plants and dying plants, a yeast Candida curvata AN723 that is capable of decomposing azodye (chrysoidine) was evaluated. When cultivation conditions favorable for decoloration by Candida curvata were examined, it was observed that the strain could decompose and decolor chrysoidine at concentrations of 0.02%. By carrying out aeration of the reacting medium decolorization of up to 94% could be acheived by the 3rd day of cultivation. The decomposition products of chrysoidine, aniline and 1, 2, 4-triaminobenzene, were identifified by paper partition chromatography and high performance liquid chromatography from the decolored effluent. It could be clarified that this strain breaks down azo bonds resolting in considerable decoloration of the effluent.
