Atrazine Degradation Pathway and Genes of <i>Arthrobacter</i> sp. FM326

Abstract

Atrazine is a triazine herbicide selectively used on maize, sorghum, cotton and other crops [1]. It is stable and persistent in soil, which has brought huge pollution to soil, surface water and groundwater [2]. In addition, atrazine is a hormone disruptor, harmful to human health and the sustainable development of the ecosystem [3-4]. At present, the way to deal with pesticide pollution is to control the quantity of pesticides in the environment, including landfill treatment of polluted soil (which is also expensive). Microbial remediation is a good alternative method that has high efficiency and leaves no residue [5-7]. Atrazine can be deaminated, dechlorinated, and ring cracked by microorganisms. To date, many atrazinedegrading microbes have been found [8-18], and some highly efficient atrazine-degrading strains have been constructed by genetic engineering [19]. Among those, the degradation pathways of the Pseudomonas sp. ADP and Arthrobacter aurescens TC1 strains have been most extensively studied, and they are used as the model strains for the study of atrazine biodegradation [20-22]. The degradation genes atzA, B, C, D, E, and F,

Atrazine Degradation by Bacillus safensis Strain BUK_BCH_BTE6 Isolated from Agricultural Land in Northwestern Nigeria

“…After the gel so lidified, the comb was removed and the gel tray was placed in the buffer tank. The gel was submerged to a depth of 2 to 5 mm by pouring 0.5× TBE into the tank (Li et al 2020).…”

Biodegradation of Atrazine Herbicide: A Mini-review

“…A study on Arthrobacter sp. strain FM326, revealed that it is a highly efficient atrazinedegrading bacteria, which expresses atrazine-degrading genes and could completely degrade atrazine into CO2 and NH3 and did not accumulate cyanuric acid in culture [28].…”
