Análisis de la aplicación de microorganismos para la degradación de plásticos

Currently one of the most common waste is plastic, it is possible to find it in large volumes in soil and water, however, the danger of this does not lie in its composition but in the amount that is produced, consumed and discarded. annually across the globe. "Each year around 500,000 billion bottles and a trillion plastic bags are manufactured in the world" (EPA, 2012); This generates research on more mechanisms to treat this contamination by plastic waste; One of the possible solutions that have been proposed is bioremediation, that is, biodegradation by means of microorganisms, such as bacteria, or mainly fungi; taking advantage of its ability to accelerate the decomposition of these polymers, minimizing collateral waste. In the present work the biological processes that a microorganism carries out when in contact with a polymer under certain conditions are explained, it is evident that two species of fungi and bacteria (Aspergillus, Fusarium, Pseudomonas and Streptomyces) are the most optimal to obtain energy and food of the polymer in question as the only source; In the same way, the need to expand the study in order to obtain a complete degradation is present.
