[Analyses of cell coloring matter and degradation products of anthraquinone dye decolorization bacteria XL-1 using ultraviolet absorption spectroscopy].
The species of cell coloring matter of anthraquinone dye decolorization bacteria XL-1, degradation reaction degrees, and the changes of molecule structure of degradation products were studied using ultraviolet absorption spectroscopy. The results indicate that the bacteria cells contain bacteria chlorophyll a and like-carotene. Its molecular structure changed evidently during the degradation process, the conjugate structure was destroyed, and new intermediate products were created.
