Potencial biorrecuperación de un suelo de minería de carbón proveniente de Amagá (Antioquia) para posterior uso agrícola

The contamination of soils produced by mining operations is one of the most common problems nowadays, since this practice affects soils in such a way that it leaves them totally deprived of nutrients and also the biotic population; In turn it harms the population surrounding it, because it ends its source of food and economic sustenance. In this research work was determined the biorrecuperación of a soil from a coal mine located in the municipality of Amagá, Antioquia, through the methodology known as bioaugmentation with an autochthonous Gram-positive bacterium and isolated of it First we determined the initial characteristics of the soil without any treatment, such as pH, conductivity, silicon and ecotoxicity. Then we inoculated the isolated bacterium and then bioaugmentation it and added to the ground, where the Lactuca sativa L was again sown, in order to compare and determine the change in the soil (biorecuperation) when applying this methodology. It was found that the optimum percentage of soil inoculated with autochthonous bacteria to add to the degraded soil is 50%, where the greatest increase in colony forming units is evident along with the percentage of germinated seeds. It is therefore stated that bioaugmentation may be a good option for the treatment of coal-contaminated soils.
