“…Actinobacteriota and Proteobacteria were the most abundant bacterial phyla in all treatments in our study. Previous studies found that Proteobacteria are the dominant microorganisms in various pesticide-contaminated soils due to their good tolerance to pollutants ( Vaishampayan et al, 2007 ; Jia et al, 2021b ). In addition, several atrazine-degrading bacteria have been identified in Actinobacteriota and Proteobacteria, such as Arthrobacter/Paenarthrobacter ( Vaishampayan et al, 2007 ), Pseudomonas ( de Souza et al, 1998 ), and Nocardioides ( Piutti et al, 2003 ).…”

Atrazine, a triazine herbicide, is widely used around the world. The residue of atrazine due to its application in the fore-rotating crop maize has caused phytotoxicity to the following crop sweet potato in China. Bioaugmentation of atrazine-contaminated soil with atrazine-degrading strains is considered as the most potential method to remove atrazine from soil. Nevertheless, the feasibility of bioaugmentation and its effect on soil microbiome still need investigation. In this study, Paenarthrobacter sp. AT-5, an atrazine-degrading strain, was inoculated into agricultural soils contaminated with atrazine to investigate the bioaugmentation process and the reassembly of the soil microbiome. It was found that 95.9% of 5 mg kg−1 atrazine was removed from the soils when inoculated with strain AT-5 with 7 days, and the phytotoxicity of sweet potato caused by atrazine was significantly alleviated. qRT-PCR analysis revealed that the inoculated strain AT-5 survived well in the soils and maintained a relatively high abundance. The inoculation of strain AT-5 significantly affected the community structure of the soil microbiome, and the abundances of bacteria associated with atrazine degradation were improved.

“…Soil samples (5 g) from the incubations were freeze-dried and extracted following the method of Jia et al, and the recovery ranged from 93.5 to 102.9%. 18 Briefly, the soil samples were extracted with methanol (25 mL) once, acetonitrile (25 mL) once, and dichloromethane (25 mL) once by repeated shaking (200 rpm, 2 h) and ultrasonication for 30 min for each extraction step. The extracts from each extraction step were separated from soil by centrifugation (12,000 g, 10 min).…”

“…Bioaugmentation refers to introducing specific microorganisms to improve the degradability of pesticide-contaminated areas, and it has emerged as a promising approach to eliminate pesticide residues . Our recent study has shown that the CPF degrading strains can enhance the dissipation of CPF and promote the mineralization of BRs, thereby reducing the persistence of CPF in soil . However, it is well known that bioaugmentation is greatly affected by environmental factors, especially soil types .…”

Chlorpyrifos (CPF) is one of the most critical insecticides in the world. However, many countries are gradually banning its use due to its reported hazardous impacts on humans. This study explored the possibility of reducing the environmental risk of CPF through appropriate agricultural management practices. Results showed that the environmental risk of CPF is lower under drainage conditions because there is more mineralization and less bound residues (BRs) than under submerged conditions. Bioaugmentation significantly enhanced the CPF mineralization and inhibited the formation of CPF-BRs. Biochar adsorbed CPF and thus reduced its bioavailability, but it could not completely eliminate the toxicity of CPF. In addition, bioaugmentation did not significantly affect the native microbial community of CPF-contaminated soil, suggesting its safety in reducing the environmental risk of CPF. The study indicated that the environmental risk of CPF could be reduced by appropriate agricultural management such as water management, bioaugmentation, soil biochar amendment, and selecting suitable soil types.
