Miranda Wang and Jeanny Yao: Two young scientists break down plastics with bacteria
兩位少年科學家用細菌分解了塑料
Miranda Wang and Jeanny Yao have identified a new bacteria that breaks down nasty compounds called phthalates, common to flexible plastics and linked to health problems. And they’re still teenagers. Full bio

當然這確實有可能
而造成黴菌意外產生
幾乎是不可能的事情
幾乎是不可能的事情
吉尼:謝謝
菲莎河(Fraser River)裡找到細菌
很容易就滲入生態環境
透過嘴巴吃下肚及吸入
都會監測河流的鄰苯二甲酸酯濃度
都會監測河流的鄰苯二甲酸酯濃度
林賽.奧爾蒂斯博士
完全改變人生的意外及發現之旅
完全改變人生的意外及發現之旅
任何東西能在培育中生長
吉尼:我開個玩笑罷了
分離到中介容器來隔離菌株
但我們又錯了
(瓊脂: 細菌培養基)
鄰苯二甲酸酯的使用情形
其實是依賴鄰苯二甲酸酯而生的
可以分解鄰苯二甲酸酯的細菌
被認為與鄰苯二甲酸酯有關
鄰苯二甲酸酯這種有害毒素
沒有分解鄰苯二甲酸酯
其實源自於垃圾掩埋場
是隨著自然界的選擇而發生
細菌可以分解鄰苯二甲酸酯的人
細菌可以分解鄰苯二甲酸酯的人
以生化降解的方式分解它們
吉尼:謝謝
ABOUT THE SPEAKER
Miranda Wang and Jeanny Yao - Science fair winnersMiranda Wang and Jeanny Yao have identified a new bacteria that breaks down nasty compounds called phthalates, common to flexible plastics and linked to health problems. And they’re still teenagers.
Why you should listen
After a visit to a plastic-filled waste transfer station last year, students Miranda Wang and Jeanny Yao learned that much of the plastic in trash may not degrade for 5,000 years. Synthesized into plastics are phthalates, compounds that make shower curtain liners, food wraps and other products bendable but may also adversely impact human reproductive development and health. As plastics slowly break down, these phthalates would leach into the surrounding environment.
So, the two young scientists tackled the problem and ultimately discovered strains of bacteria that have the potential to naturally degrade phthalates. Their work earned a regional first place in British Columbia for the 2012 Sanofi BioGENEius Challenge Canada, as well as a special award for the most commercial potential at the contest’s finals.
