摘要: Abstract The wide application of mesosulfuron-methyl (MS) in soil may affect microbial community, yet the information is limited. In this work, two distinct types from Anyang (AY) and Nanjing (NJ) were spiked with MS (0, 0.006, 0.06, or 0.6 mg kg–1) incubated for 90 days. decreased bacterial fungal (except last sampling) abundance altered their diversity community. Five biomarkers species help degradation more increased xenobiotics biodegradation pathways also observed 0.6 mg kg–1 treatment AY soil. A co-occurrence network revealed grouped one module all soils, suggesting these act concert to degrade MS. impacted N transformation increasing N2-fixing bacteria both soils ammonia-oxidising (AOB) NJ decreasing ammonia-oxidizing archaea (AOA) AY. contents NO3–-N NH4+-N by Structural equation models that fungi was responsible contents. conclusion, work aids safety assessments degradation-related research
