Actinomycete strains isolated from 2,4,6-trinitrotoluene (TNT)-contaminated and uncontaminated environments were compared for TNT tolerance and abilities to transform TNT. Regardless of previous TNT exposure history, no significant differences in TNT tolerance were seen among strains. Selected strains did not significantly mineralize [14C]TNT. The actinomycetes did, however, transform TNT into reduced intermediates. The data indicate that, in actinomycete-rich aerobic environments like composts, actinomycetes will transform TNT into intermediates which are known to form recalcitrant polymers.
对从受2,4,6-三硝基甲苯（TNT）污染和未受污染环境中分离出的放线菌菌株进行了TNT耐受性和转化TNT能力的比较。无论之前的TNT暴露历史如何，各菌株之间在TNT耐受性方面均未观察到显著差异。所选菌株并未使[14C]TNT发生显著矿化。然而，放线菌确实将TNT转化为了还原中间体。数据表明，在像堆肥这样富含放线菌的需氧环境中，放线菌会将TNT转化为已知会形成难降解聚合物的中间体。
