Abstract

The bacterial strain JE-1 degrading and utilizing Congo Red as a sole carbon source was isolated from dye-contaminated soul and Identified as Enterobacter species. Enterobacter sp. JE-1 had the highesc decolorization ability when It was cultured In the medium containing 0.05% $NH_4N0_3, 0.05% K_2HP0_4, 0. 03%$ $MgSO_4$, $7H_2O$, 0.025% Congo Red, initial pH 7.0 at $30^{\circ}C$, respectively Enterobacter sp. n-1 had the relatively high substrate specificity. The dye decolorizing activity was exclusively extracellular. The expected metabolic intermediates of Congo Red by Enterobacter sp.15-1 were analyzed by GC/MS. As a result. metabolic products like hauadecanoic acid, 1, 2, 3-triphenylcyclopropene, aliphatic hydrocarbons butylester were detected. Benzldine 616 not detected.
