Abstract
The specific strain, Flavobacterium sp. BX26, was examined to decolorize bromamine acid, which is an important intermediate for the synthesis of anthraquinone dyes. The results showed that Flavobacterium sp. BX26 had a high capacity to decolorize bromamin acid within a relatively short time. The decolorization was an inductive process. Flavobacterium sp. BX26 cannot use bromamine acid for growth, but its metabolic intermediates were. It was found that the decolorizing process mainly took place outside the cells or the functional enzymes might be extracellular enzymes. Some factors including salinity, heavy metal ions, complexing agent like EDTA, and the lack of oxygen can seriously inhibit the decolorization process.
