Plastics Remediation



An easy way to discover microbes that break down plastic is to find plastic that is breaking down, analyze it, and find out what microbes are doing the work. A good place to find disintegrating plastic is in your kitchen sink. Probably one out of ten houses has a splash guard in the late stages of breaking down. So if you are a scientist who wants to learn how to disintegrate plastic using microbes, go cut the disgusting black plastic splash guard out of someone's sink and put it under a microscope! (I discovered this last night when I was scraping out what remained of my old splash guard.)

"What scientists have recently discovered is that the sudden appearance of concentrated nutrients is waking up and attracting dormant microbial life."

L.A. Times: Scientists find microbes thriving on plastic marine debris. "Plastisphere, a biological wilderness on microbial reefs of polyethylene and polypropylene in the open ocean teeming with single-celled animals, fungi and bacteria, many of them newly discovered. Some may be pathogens hitching rides on floating junk." . . . " 'We were surprised to find microbes in such high numbers on these plastics,' said Tracy Mincer, an associate scientist in marine chemistry and geochemistry at Woods Hole Oceanographic Institution and coauthor of a report on the findings published online in June in Environmental Science and Technology." "These unique menageries, which arose on plastic debris introduced to the world's ocean over the last six decades, make up extensive food chains of bacteria and single-celled animals that produce their own food, bacteria that feed on their waste products and predators that feed on all of them." "Another surprise: Some microbes seem to have acquired a taste for polypropylene. Others, however, prefer polyethylene." Led by microbial ecologist Erik Zettler of the Sea Education Assn., biologist Linda Amaral-Zettler of the Marine Biological Laboratory, and Mincer—all in Woods Hole, Mass."

wasterecyclingnews.com Yale undergraduates, including Pria Anand, have discovered organisms in Amazon Rainforest fungi which can degrade polyurethanes. The discovery, which is featured in the journal Applied and Environmental Microbiology, may lead to innovative ways to reduce waste in the world's landfills, the university said in a press release.

bbc.co.uk "At the UK's University of Sheffield, scientists are investigating how they could accelerate the speed at which the plastic breaks down by looking at micro-organisms already found in the sea that naturally feed on plastic.

Nature.com reports that microbes are eating plastic in the ocean. The article reports: "Plastic-eating bacteria might help explain why the amount of debris in the ocean has levelled off, despite continued pollution."
