The major concern over Global Warming has made many people become more environmentally conscious. Numerous amount of environmentally-friendly methods have been promoted and one of those method is reducing the use of plastic bags. Unfortunately, promotion and practice does not always go hand-in-hand. There are still many people that continuously use plastic bags. So, instead of reducing the use of plastic bags why not make plastic bags that are eco-friendly?
According to an article in Science Daily "Bioengineers Succeed in Producing Plastics Without the Use of Fossil Fuels", a team of South Korean Scientists discovered a method of producing biodegradable plastic in a more efficient manner. The research team, which was led by Professor Sang Yup Lee focused on polylactic acid or PLA. PLA which is a bio-based polymer is an eco-friendly alternative to petroleum based plastics because it's biodegradable and is less toxic to humans. The research team discovered a one-step method of obtaining PLA by using a metabolically engineered strain o E. coli. Professor Lee believes, "This strategy will be useful for developing other engineered organisms capable of producing various unnatural polymers by direct fermentation from renewable resources."
