87 microbes were isolated from dyeing wastewater collected at Dongducheon and Banweol industrial complex. Five microbes showed excellent ability of color removal and were identified as Shewanella putrefaciens, Aeromonas salmonicida(3 different strains), and Pseudomonas vesicularis. Five identified strains had optimal pH and optimal temperature as 7.0 and 30$^{\circ}C$ for cultivation, and showed morphological characteristics of Gram negative, oxidase negative, rod shape, and non-motility, but their biochemical characteristics were distinguishable. Each single strain of five microbes were tested in the 500 mL flask to treat dyeing wastewater, and achieved about 35% color removal efficiency in average. When two strains were selected and applied to the treatment at same time, color removal efficiency was increased up to 65%. While three or more associations of each strain did not show the improvement of color removal. Inhibition effects by $Mn^{2+}\;and\;Fe^{3+}$ on the dye degradation were tested and resulted in no effect under 70 ppm concentration.
