Studies from Sookmyung Women's University Reveal New Findings on Enzymes and Coenzymes [Biodegradation of polylactic acid (PLA) fibers using different enzymes]

By a News Reporter-Staff News Editor at Life Science Weekly -- Current study results on Enzymes and Coenzymes have been published. According to news reporting originating in Seoul, South Korea, by NewsRx journalists, research stated, "The biodegradability of polylactic acid (PLA) nonwovens was evaluated using enzymatic degradation. To evaluate enzyme biodegradation, three enzymes, lipase, esterase, and alcalase, which are known to hydrolyze PLA effectively, were selected."

The news reporters obtained a quote from the research from Sookmyung Women's University, "Degradation time was determined under optimal enzyme treatment conditions. Enzymatic degradation affected the width and thickness of PLA nonwovens. In addition, the degree of crystallinity of the PLA nonwovens increased with time for the first 21 days of enzyme biodegradation and then decreased. Alcalase was more efficient than lipase and esterase in degrading the PLA nonwovens. Degradation was found to create cracks on the fiber surface, making the fibers rough. Weight loss and change in tensile strength were not significant, and the observed changes could be due to the cracks on the surface."

According to the news reporters, the research concluded: "Our findings propose the mechanism of enzymatic degradation of PLA nonwovens, which might be useful for waste management in the textile industry."
