To assess the co-catabolism of phenanthrene and tricyclazole in different samples, the interaction during the degradation of phenanthrene and tricyclazole were investigated in medium, soil and soil/spent mushroom compost (SMC) mixture. Generally, tricyclazole showed a negative influence on the activity of phenanthrene dioxygenase and it inhibited the degradation of phenanthrene prominently, both in cultures of phenanthrene catabolic isolates (Sphingomonas paucimobilis ZX4 and the mixed flora M1) and soils, while a similar inhibition caused by phenanthrene was also found for the degradation of tricyclazole in soil/SMC. However, the inhibition effect on phenanthrene degradation was eliminated in soil/SMC mixture, due to the abundant microorganisms and enormous catabolic potential in SMC. Furthermore, it was proved that the negative influence between phenanthrene and tricyclazole was most likely derived from the molecular similarity and it tended to decrease with improved microbial diversity in environment.

在介质，土壤和土壤/堆肥混合物中，菲和三环唑的降解之间存在负向相互作用。

为了评估菲和三环唑在不同样品中的共分解代谢，在培养基，土壤和土壤/废蘑菇堆肥（SMC）混合物中研究了菲和三环唑降解过程中的相互作用。通常，三环唑对菲双氧合酶的活性有负面影响，并且在菲分解代谢物（鞘脂单胞菌ZX4和混合菌群M1）和土壤中均显着抑制菲的降解，而菲的类似抑制作用是还发现其在土壤/ SMC中降解三环唑。然而，由于土壤中丰富的微生物和SMC中巨大的分解代谢潜力，在土壤/ SMC混合物中消除了对菲降解的抑制作用。此外，
