Abstract
One of the most used polymers in the industry is low-density polyethylene thanks to its physicochemical properties, resistance to high temperatures, and mechanical hardness however, given the massive use that society has given to this material, it has brought with it problems where its accumulation and final disposal have affected the ecosystem and people’s health. For this reason, this project seeks to carry out a biodegradation model of LDPE mediated by fungal cultures with Aspergillus brasiliensis in submerged liquid fermentation, with the colonization of the material. The process was conducted on a laboratory-scale bioreactor prototype under aerobic conditions. After one month of treatment, the results were analyzed with the help of analysis of Scanning Electron Microscopy (SEM) and Fourier Transform Infrared Spectroscopy (FTIS), including the biodegradation process with the colonization of the material and the formation of biofilms, reaching a biodegradation percentage of 1.89% +/-0.56.
