Application of a simazine degrading bacterium, Arthrobacter ureafaciens XMJ‐Z01 for bioremediation of simazine pollution

Abstract

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 simazinecontaminated 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.

Retracted: Synthesis and surface modification of mesoporous metal-organic framework (UiO-66) for efficient pH-responsive drug delivery and lung cancer treatment

“…Stimuli-responsive drug delivery system is an efficient technique for cancer treatment [1][2][3][4][5]. Various materials have been developed for drug delivery, including metal-organic frameworks (MOFs), magnetic materials, inorganic materials, and liposomes [6][7][8][9]. The stimulus used to trigger the drug release at the target sites includes temperature, light, pH, redox reagent, etc [10][11][12][13].…”

“…Generally, a pH-sensitive polymer with high biocompatibility is coated on the surface of a delivery vehicle. Among various pH-sensitive materials, carboxymethylcellulose (CMC) is an anionic water-soluble natural polymer [16][17][18][19]. It has been widely used in the drug delivery system for pH-responsive drug release, due to the characteristics of high pH sensitivity, high biocompatibility, nontoxicity, and high hydrophilicity [20][21][22][23].…”

“…On the basis of this, it can also degrade simazine. 572 The strain XMJ-Z01 is highly resistant to simazine and can tolerate simazine at a high level.…”

“…In conjunction with it, Arthrobacter ureafaciens bacterium secretes deglycosylation enzymes capable of cleaving all nonreducing unbranched N-acetyl­neuraminic and N-glycolylneuraminic acid residues by hydrolysis. On the basis of this, it can also degrade simazine . The strain XMJ-Z01 is highly resistant to simazine and can tolerate simazine at a high level.…”

Synthesis and application of new silver and sulfur decorated S-doped reduced graphene oxide in ultra-trace analysis of pesticides by ion mobility spectrometry

“…Simazine, as an endocrine disrupting chemical, can exacerbate infectious diseases, as well as interfere with the human immune system. 14 Alachlor (ALA) is a herbicide from the group of chloroacetanilides and is extensively used in cotton, maize, soybean, brassica, and sugarcane fields. It is absorbed by plant shoots and prevents lipid, protein, and gibberellin synthesis.…”
