Biotecnologia per a la recuperació sostenible de sòls contaminats

Soil is a living and life-giving non-renewable natural resource. Pollution associated with human activity is one of the main agents of soil degradation. Hydrocarbons are the most abundant group of soil pollutants, including the toxic and carcinogenic polycyclic aromatic hydrocarbons (PAHs). Bioremed...
