ISOLATING, SCREENING AND SELECTING POLYETHYLEN ABLE OF DEGRADING MICROORGANISMS
Main Article Content
Abstract
Polyethylene has been used increasingly over time, and its degradation is becoming a great challenge. Annually, approximately 500 billion to 1 trillion polyethylene carry-bags are being consumed worldwide. This study aimed at isolating, screening and selecting microorganisms that are able to degrade polythene. A total of 25 microorganism were isolated. Bacillus drentensis, Bacillus subtilis ATCC 5230 and Aspergillus oryzae ATCC 10124 were ones of the isolates identified in this study. They have the potential to degrade PE. The extent of biodegradation on the polyethylene sheets was assessed by various techniques including weight loss analysis (48.8%), Fourier Transform Infrared Spectroscopy (FTIR), PE distance from environmental surfac, tensile and change of surface structure of PE (SEM), genus Bacillus drentensis were confirmed to be good candidates for PE biodegradation. Further research is also recommended to survey biodegradation of strains of microorganisms preservation in strain collection.
