In recent years, microorganisms capable of degrading it have been reported, most of which come from environments in which PVC is accumulated.

description PVC is one of the most widely used plastics today and the one that produces the most waste. In recent years, microorganisms capable of degrading it have been reported, most of which come from environments in which PVC is accumulated. The aim of this work was to study the degradation of PVC without plasticizer, from fungi isolated from a soil sample contaminated with PVC resin. The fungi were isolated and morphologically characterized, 30 morphospecies were obtained, 8 were chosen to undergo preliminary tests in a medium whose only carbon source was a PVC film. Growth curves of the two isolates with better results were made and their molecular identification showed that they corresponded to Penicillium sp. and Mucor sp., the latter gained biomass from PVC and in both cases, the films showed visible changes, which were supported by infrared spectra. Although the results shown in this article are preliminary, they open the door to new forms of PVC waste degradation that are very persistent.

El PVC es uno de los plásticos más usados y de los que más residuos se producen. En los últimos años, se han reportado microorganismos capaces de degradarlo y que en su mayoría provienen de ambientes en los que se acumula. El objetivo de este trabajo fue estudiar la degradación del PVC sin plastificante, a partir de hongos aislados de una muestra de suelo contaminada con resina de PVC. Los hongos se aislaron y caracterizaron morfológicamente, obteniendo 30 aislamientos de los que se escogieron 8 para someterlos a pruebas preliminares, en un medio cuya única fuente de carbono era una película de PVC. Se hicieron curvas de crecimiento de los dos aislamientos con mejores resultados, y su identificación molecular mostró que correspondían a Penicillium sp. y Mucor sp.. Este último ganó biomasa a partir del PVC y en los dos casos, las películas mostraron cambios visibles, que fueron respaldados por espectros de infrarrojo. Aunque los resultados mostrados en este artículo son preliminares, abren la puerta a nuevas formas de degradación de los residuos de PVC, que son muy persistentes.
