Bioremediation of Emerging Contaminants Using Antarctic Ampicillin-Degrading Bacteria

The project was based on the study of a new Antarctic bacterial species, P. violetae (named in honor of Chilean artist and musician Violeta Parra (1917–1967)), isolated and identified in the Bionanotechnology Laboratory of Universidad Andrés Bello in Chile, from soil samples taken from the Unión Glacier in Antarctica. This strain is characterized by being part of the Pseudomonas genus, being a Gram-negative bacillus, and having a growth temperature range between 0 and 30°C. Finally, its resistance in a medium containing ampicillin and its capacity to degrade it were evaluated. The use of this bacterium is proposed as a feasible method to combat the emerging contamination of antibiotics in wastewater.
