Microbes and Plastic: A Love Hate Relationship?
[ alt-No ] https://i0.wp.com/cos.northeastern.edu/wp-content/uploads/2019/10/ocean_plastic.jpg?w=800&ssl=1 When plastic in the ocean is broken down by the sun, what happens to the surrounding ocean and itβs living inhabitants? To answer this question, visiting graduate student Lixin Zhu, Associate Professor Aron Stubbins https://cos.northeastern.edu/people/aron-stubbins/, and their team exposed plastic to UV radiation in the lab and observed the impact on bacteria and other microbes living in surrounding ocean water. Results indicated that as the degraded plastic released dissolved organic carbon, some microbes were able to utilize the additional carbon to increase their growth, but for other microbes, growth was inhibited by the presence of degraded plastic. These findings, recently published in The Journal of Hazardous Materials https://www.sciencedirect.com/science/article/pii/S0304389419310192 illustrate the complexity of interactions between marine debris, the environment, and marine organisms. The Stubbins lab will continue and extend this research investigating sunlightβs impact on ocean plastic, thanks to a new grant https://news.northeastern.edu/2019/08/07/nearly-eight-million-tons-of-plastic-are-missing-from-our-oceans-new-research-shines-some-light-on-what-may-be-happening/ from the National Science Foundation. -- With over 1,000,000 million devices now running Windows 10, customer satisfaction is higher than any previous version of windows. |
