Randomized trial examines p-nitrophenol degradation in soil, suggesting ways to enhance bioremediation.

This study aims to understand the degradation kinetics of p-nitrophenol and the microbial dynamics involved under natural conditions.
Conducted a 168-day sand box experiment with p-nitrophenol-contaminated soil.
Analyzed concentrations, physico-chemical properties, enzyme activities, microbial communities, and C/N cycling genes at multiple time points.
Used 16S rRNA/ITS sequencing and KEGG annotation to evaluate microbial changes and functional gene expression.
p-Nitrophenol degraded from initial concentrations of 10–40 mg kg−1 to 2 mg kg−1 within 126 days, following first-order kinetics.
Microbial diversity decreased in high-contamination zones but recovered by Day 126, with Bacillus and Penicillium dominant early, and Sphingomonas and Arthrobacter later.
Key functional genes showed peak expression on Day 84, correlating with PNP degradation phases.

Dong et al. (2026) studied this question.
