Supporting evidence — 8 representative gaps

• Assessing Microbial Activity and Rhizoremediation in Hydrocarbon and Heavy Metal-Impacted Soil (2025) · Microorganisms · cited 20× · doi

  The paper identifies a gap in the understanding of plant-microbe interactions in the rhizosphere and their impact on PHC degradation in heavy metal co-contaminated soil. There is a need for effective remediation strategies for PHC-heavy metal co-contaminated soils. The study highlights the importance of considering the impact of plant species on microbial communities and PHC degradation.

• Assessing Microbial Activity and Rhizoremediation in Hydrocarbon and Heavy Metal-Impacted Soil (2025) · Microorganisms · cited 20× · doi

  The study faced challenges in terms of soil contamination and the need for effective remediation strategies. The experiment had to consider the impact of plant species on microbial communities and PHC degradation. The study had to account for the co-contamination of heavy metals and petroleum hydrocarbons in the soil.
