A bacterium named XMJ‐Z01 is screened from soil and identified as Arthrobacter ureafaciens, which can efficiently degrade simazine. The strain XMJ‐Z01 is highly resistant to simazine and can tolerate simazine at a level of not less than 2000 mg/L. The degradation efficiency of simazine (100 mg/L) in liquid medium by strain XMJ‐Z01 can reach about 99.1% in 7 days. Adding a small amount of fresh soil during the degradation of simazine (in culture medium) by strain XMJ‐Z01 can improve the degradation efficiency. The use of strain XMJ‐Z01 in simazine‐contaminated farmland will accelerate the degradation of simazine residues in the soil and reduce its leakage into the deep soil; in addition, it is also beneficial to reduce the adverse effects of simazine on soil enzyme. Therefore, it is considered that strain XMJ‐Z01 can be used for bioremediation of simazine pollution in soil.

辛嗪降解细菌尿素节杆菌XMJ-Z01在生物修复Simazine污染中的应用

从土壤中筛选出一种名为XMJ-Z01的细菌，并将其鉴定为尿素节杆菌，可以有效降解simazine。XMJ-Z01菌株对西马津具有高度抗性，并且对西马津的耐受水平不得低于2000 mg / L。XMJ-Z01菌株在液体培养基中对simazine（100 mg / L）的降解效率在7天内可达到约99.1％。在菌株XMJ-Z01降解simazine（在培养基中）的过程中添加少量新鲜土壤可以提高降解效率。XMJ-Z01菌株在被simazine污染的农田中的使用将加速土壤中simazine残留物的降解，并减少其向深层土壤的泄漏。此外，减少西玛津对土壤酶的不利影响也是有益的。因此，可以认为XMJ-Z01菌株可用于土壤中Simazine污染的生物修复。
