Item Degradación del polietileno de baja densidad mediada por hongos filamentosos: Una revisión sistemática(Universidad Santiago de Cali, 2023) Banguera Ortiz , Adriana Sofia; Rangel Hoyos, Patricia; Rojas Barreto, Julián Alonso; Caicedo Bejarano, Luz DaryLow-density polyethylene (LDPE), is used in the food, clothing, transportation, construction, and medical industries. It is a high-consumption material and due to its physicochemical nature is extremely durable, recalcitrant, relatively unbreakable, and could be present for more than 50 years in the environment. Their accumulation generates serious pollution damage affecting natural resources, threatening fauna, wildlife, and even public health. In most landfills plastic waste represents the largest fraction, reaching up to 25% by weight in some sites. Degradation of LDPE can occur by chemical, physical, and biological methods, which can be affected by temperature, UV light, and enzymatic actions of both bacterial and fungal microorganisms. In biodegradation studies, fungi are considered potential candidates for LDPE degradation, due to their ability to adhere to the polymer surface and the production of intra- and extracellular enzymes. This review reports fungi isolated from LDPE-rich landfills with LDPE biodegradative capacity. Some fungi reported were of the genus Aspergillus, Penicillium, Rhizopus, among others. Scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR) techniques are used to measure biodegradation and although other reviews have been analyzed, there is little information on fungi extracted from landfills used for LDPE biodegradation
