Foreign Title : Biodegradación de polietileno de baja densidad por acción de un consorcio microbiano aislado de un relleno sanitario, Lima, Perú. One prevalent type of plastic is polyethylene, a semicrystalline polymer built from ethylene subunits. PE such as low density polyethylene (LDPE) and high density polyethylene (HDPE), have been used for biodegradation studies [ 86, 97] (Fig. 2 ). LDPE was prepared by the high pressure polymerization of ethylene. The presence of branched chains is responsible for the low density of LDPE. The biodegradation was carried out for a period of 55 days. Following 30 days cultivation of the IRE-31 strain, the biodegradation of linear low-density PE particles was evidenced clearly by morphological changes of the polymer surface monitored by scanning electron microscopy and the formation of additional carbonyl groups in the polymer chains indicated by Fourier transform infrared spectroscopy. Bo-Yu Peng State Key Laboratory of Pollution Control and Resource Reuse, College of Environmental Science and Engineering, Tongji University, Shanghai, 200092, China. Petroleum-derived (petro-)plastics have many desirable characteristics.
