This article presents the results of the adaptative versatility and tolerance of a bacterial consortium made up of 10 bacterial stocks endemic to a contaminated soil coming from an onion farm located near Laguna de Tota, Aquitania, Boyacá, Colombia. This soil has been exposed to the uncontrolled use of nitrogen rich fertilizers. The bacterial consortium from the soil is made up of Bacillus megaterium, Bacillus licheniformis, Pseudomonas stutzeri, Acinetobacter sp, Propionibacterium sp, Peptoestreptococcus sp, coagulasa negative sthaphylococci, Corynebacterium sp, Clostridium sp, and Actinomyces sp. It was demonstrated that the isolated microorganisms have in vitro denitrifying capabilities, thus transforming nitrates to molecular nitrogen. The isolated bacterial association constitutes a bioremediation alternative to recover the soil that has been contaminated by the excess of nitrogen rich fertilizers.
