| Summary: | The biodegradation of polymeric materials has become a necessity given the current problematic related to the management of plastic waste that directly impacts ecosystems and the low efficiency of currently used alternatives. The present investigation was focused on the evaluation of the biodegradation process of low-density polyethylene sheets using inoculums of a) Aspergillus niger, b) Aspergillus brasiliensis and a c) consortium of these two strains in compost-type soil matrix with control treatments using sheets of polylactic acid determining the percentage of biodegradability. The highest percentages of LDPE biodegradation were evidenced using Aspergillus brasiliensis strain as inoculum in a period of 68 days. The studies carried out with this strain are still limited within the scientific bibliography, therefore, this project is considered relevant in the characterization of the biodegradation processes of complex polymers such as low-density polyethylene. |
