Bioremediation (natural attenuation and biostimulation) of diesel-oil-contaminated soil in an alpine glacier skiing area

Article Abstract:

Bioremediation using naturally stimulated soil bacteria is feasible and effective, according to researchers who used this technique to remediate an alpine glacier area 2,875 meters above sea level that was contaminated with diesel oil. Biostimulation involves fertilizing soil with nitrogen, phosphorus, and potassium to stimulate the growth of indigenous soil bacteria.

Characterization of hydrocarbon-degrading microbial populations in contaminated and pristine Alpine soils

Article Abstract:

Research has been conducted on biodegradation of petroleum hydrocarbons in Alpine soils. The authors have investigated the prevalence of genotypes involved in n-alkane, aromatic hydrocarbon and polycyclic aromatic hydrocarbon degradation using PCR hybridization analyses of the soil microbial community DNA.

Efficiency of indigenous and inoculated cold-adapted soil microorganisms for biodegradation of diesel oil in alpine soils

Article Abstract:

The efficiency of indigenous and inoculated cold-adapted soil microorganisms for biodegradation of diesel oil in alpine soils was evaluated to show patterns of decontamination and biostimulation of indigenous soil microorganisms. Results reveal that microorganisms are beneficial to in environments where contaminants resist biodegradation by indigenous microorganisms. Furthermore, environmental parameters play crucial roles in in determining the rate of degradation at contaminated sites.
