Di-(2-ethylhexyl) phthalate-degrading functional microorganisms were identified in black soil based on high throughput analysis.

ABSTRACT: Di-(2-ethylhexyl) phthalate (DEHP) has become an increasingly serious pollutant in soils. Microbial degradation represents a highly promising approach for its remediation. In this study, four black soils were used to simulate the natural degradation of DEHP over a 75-day microenvironmental experiment. High-throughput analysis was conducted to investigate the distribution and abundance of functional genes in soil microorganisms, aiming to explore functional microbial information. The degradation efficiency of DEHP in black soils was 76.37 %, 74.16 %, 92.21 %, and 75.35 %. The α-diversity of microbial community was positively correlated with the degradation rate. Actinobacteria and Proteobacteria exhibited sensitivity to DEHP contamination. Xanthomonaceae, Sphingomonadaceae, Hypomicrobiaceae
