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.
