使用浓缩技术，从每年四次使用这种除草剂的土壤中分离出能够降解EPTC的细菌和真菌。29株降解EPTC的真菌分属于11个分类群，其中以尖孢镰刀菌最为常见。在4℃营养琼脂上放置15个月后，有24个菌株对EPTC有显著的降解作用，其中青霉、青霉和双孢杆菌的降解率最高。在110株细菌中，有9株在贮藏3个月后降解了大量的EPTC，但在15个月后没有一株降解EPTC。细菌对EPTC降解能力的丧失归因于携带EPTC分解基因的质粒的丢失。
Bacteria and fungi capable of degrading EPTC were isolated from soil which had received four annual applications of the herbicide, using an enrichment technique. The 29 EPTC-degrading fungal isolates belonged to 11 taxa, of whichFusarium oxysporumwas the most frequent. After 15 months storage on nutrient agar at 4 °C, 24 of the isolates degraded significant amounts of EPTC.Paecilomyces, PenicilliumandDiheterosporawere the most efficient decomposers. Of 110 bacterial isolates, 9 degraded significant amounts of EPTC after 3 months storage, but none degraded EPTC after 15 months. The loss of EPTC-degrading ability by the bacteria is attributed to the loss of plasmids carrying the genes for EPTC decomposition.
