摘　　要：应用紫外-可见吸收光谱法研究了一株蒽醌染料降解菌活细胞色素的种类、降解反应程度以及降解产物分子结构的改变。结果表明,蒽醌染料降解菌活细胞中含有细菌叶绿素a以及细菌类胡萝卜素,降解过程中染料分子结构发生了明显的改变,分子原来的共轭结构被破坏,并有新的中间产物生成。The species of cell coloring matter of anthraquinone dye deodorization 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.
