The fungus Cunninghamella elegans was used to biotransform 6-nitrochrysene, a mutagen that is a widespread environmental contaminant. After 6 days, 74% of the 3H-labeled 6-nitrochrysene added had been metabolized to two isomeric sulfate conjugates. These conjugates were separated by high-performance liquid chromatography and identified by UV-visible, 1H nuclear magnetic resonance, and mass spectral techniques as 6-nitrochrysene 1-sulfate and 6-nitrochrysene 2-sulfate.
线虫状小克银汉霉被用于对6-硝基屈进行生物转化,6-硝基屈是一种诱变剂,也是一种广泛存在的环境污染物。6天后,添加的3H标记的6-硝基屈中有74%已代谢为两种异构硫酸酯共轭物。这些共轭物通过高效液相色谱法分离,并通过紫外可见光谱、1H核磁共振光谱和质谱技术鉴定为6-硝基屈1-硫酸盐和6-硝基屈2-硫酸盐。
