The decolorization of bromamine acid by Flavobacterium sp. BX26

The specific strain, Flavobacterium sp. BX26, was examined to decolorize br omamine acid,which is an important intermediate for the synthesis of anthra quinone dyes. The results showed that Flavobacterium sp. BX26 had a high ca pacity to decolorize bromamin acid within a relatively short time. The deco lorization was an inductive process. Flavobacterium sp. BX26 cannot use bro mamine acid for growth, but its metabolic intermediates were. It was found that the decolorizing process mainly took place outside the cells or the fu nctional enzymes might be extracellular enzymes. Some factors including sal inity, heavy metal ions, complexing agent like EDTA, and the lack of oxygen can seriously inhibit the decolorization process.
