Progress in biostimulation-based remediation of TPH-contaminated soils: a comprehensive review.

ABSTRACT:

Background

Petroleum pollution in soils poses a significant global environmental threat, primarily due to increased industrial activities and oil spills. Biostimulation, a bioremediation strategy that enhances indigenous microbial activity through nutrient amendment, has gained prominence for its sustainability and effectiveness.

Methods

This review consolidates findings from 276 peer-reviewed studies published between 2000 and 2025, covering the application of organic amendments, mineral nutrients, and biochar. It further analyzes microbial community responses, degradation efficiency, and synergistic treatment outcomes under varied environmental conditions.

Results

Biostimulants such as compost, nitrate, and phosphate significantly enhance microbial degradation of to
