Abstract: The optimal degradation conditions of 1-amino-4-bromoanthraquinone-2-sulfonic sodium(ABAS) by strain HP3 temperature=30℃, pH=7.0, speed of shake-bed=160r/min and NaCl=0 in the culture basis were obtained by orthogonal test. Under these conditions, the ABAS degradation followed negative exponential model. The addition of glucose and (NH4)2SO4 could greatly enhance the degradation rate of ABAS by the strain. All experimental metal compounds restrained the degradation of ABAS in different degrees, in which HgCl2 and AgNO3 could control the degradation most obviously. Strain HP3 also degraded anthraquinone, 1,4,5,8-tetrahydroanthraquinone and 1-animoanthraquinone 2-sulfonic sodium. Degraded by HP3, the absorption spectrum of ABAS changed greatly showing that the degradation was not concentrated on single basis. TOC analysis showed a part of organic carbon from destroyed anthraqui none of ABAS was utilized; and the medial prduct o-phthalic acid formed as determined in liquid chromospreetrum. The molecule weights of the final products from the ABAS degradation were 289 and 290.
