Abstract

The fate of glycerol trinitrate when exposed to microbial attack has been investigated. Contrary to some earlier reports, this compound was readily biodegraded by employing batch or continuous techniques under a variety of cultural conditions. Breakdown of glycerol trinitrate took place stepwise via the dinitrate and mononitrate isomers, with each succeeding step proceeding at a slower rate. After a residence time of 8 to 15 h, none of the glycerol nitrates could be detected in the effluent from a continuous-culture apparatus (chemostat) supplied with an influent containing 30 mg of glycerol trinitrate per liter.

摘要

甘油三硝酸酯在遭受微生物攻击时的命运已得到研究。与一些早期报告相反,在各种培养条件下,采用分批或连续技术时,该化合物很容易被生物降解。甘油三硝酸酯通过二硝酸酯和单硝酸酯异构体逐步分解,每一步后续反应的速率都较慢。在停留时间为8至15小时后,在配备有每升含30毫克甘油三硝酸酯进水的连续培养装置(恒化器)的流出物中,检测不到任何甘油硝酸盐。
