2026-09-18 Article“Freeze-thaw cycles and biodegradable microplastics alter the microbial degradation of atrazine in mollisols”（new） doi:10.57760/sciencedb.iga.001gq en This thesis is based on a systematic study on the impact of freeze-thaw cycles (FTCs) on the microbial degradation of the herbicide atrazine in black soil. The study used typical black soil from Northeast China (collected from Hailun, Heilongjiang Province) as the test soil. Four different frequency and melting temperature freeze-thaw cycle patterns were set to simulate the seasonal freeze-thaw process under natural conditions. Through indoor microcosm cultivation experiments, the degradation dynamics and changes in bioavailability of atrazine were measured. Additionally, high-throughput sequencing and metagenomics techniques were employed to analyze the structure of the soil microbial community, the characteristics of co-occurrence networks, and the response patterns of functional genes.
