Organophosphorous insecticides are used extensively in agriculture. As a group, they are easily degraded by bacteria in the environment. However, a number of them have half-lives of several months. Little is known about their biodegradation by fungi. We showed that Phanerochaete chrysosporium mineralized chlorpyrifos, fonofos, and terbufos (27.5, 12.2, and 26.6%, respectively) during an 18-d incubation in nutrient nitrogen-limited cultures. Results demonstrated that the chlorinated pyridinyl ring of chlorpyrifos and the phenyl ring of fonofos undergo cleavage during biodegradation by the fungus. The usefulness of P. chrysosporium for bioremediation is discussed.
有机磷杀虫剂在农业中被广泛使用。作为一个类别，它们在环境中很容易被细菌降解。然而，其中一些的半衰期为数月。关于它们被真菌进行生物降解的情况知之甚少。我们发现，在营养氮受限培养物中进行18天培养期间，黄孢原毛平革菌将毒死蜱、地虫硫磷和特丁硫磷矿化（分别为27.5%、12.2%和26.6%）。结果表明，毒死蜱的氯化吡啶环和地虫硫磷的苯环在被该真菌生物降解过程中发生了裂解。讨论了黄孢原毛平革菌在生物修复中的实用性。
