Ten st rains, w hich can evidently degrade and decolorize bromamine acid, an intermediate of anthraquinonedye, have been isolated from sludge of chemical plant. Invest igat ion of the characterist ic of st rain N1has been made. Experimental result s show that bromamine acid can be the only carbon source of strain N1. Butthe velocity of decolorizing becomes much slow er when it is used as the only nitrogen source of the same st rain.Decolorizing of bromamine acid is considerably affected by temperature and pH. T he best g row th condit ion forthe st rain is 30 e, pH 7. 2.
Key words： bromamine acid; biodegradation; strain isolating
