This plastic is the common polymer polybutylene succinate (PBS), which is generally regarded as an ecofriendly polymer because it naturally biodegrades when exposed to the elements; however, in marine environments it does so to only a limited extent. The biodegradability of PBS has led to an increase in its use since the early 1990s in industrial plastics, including mulching films, compostable bags and packaging. However, many of these discarded plastic items wind up in the oceans where they then remain permanently.<\/p>\n<p>In order to see what microorganisms can degrade PBS, scientists at Hokkaido University and their colleagues at the Mitsubishi Chemical Group in Japan decided to investigate. They did this by examining the effects of microbes gathered from natural seawater off the coasts of Japan to identify several types of marine bacteria that could do the job. In the process they identified the enzyme responsible for degrading PBS in a specific strain of bacteria called Vibrio ruber. They named the enzyme PBSase. The scientists then used molecular biological techniques to insert the gene for PBSase into the common bacterium Escherichia coli, which they cultured to produce highly purified samples of the enzyme, as they detail in a study.<\/p>\n<p>The purified enzyme allowed the researchers to examine its structure and their simulations suggest it is closely related to a different enzyme known to degrade another common polymer: polyethylene terephthalate (PET). \u201cBy exploring the enzyme\u2019s activity in degrading other polymers, such as PET, we hope that our work will contribute more widely to advances in plastic recycling technologies,\u201d notes Tomoo Sawabe, who led the research team at Hokkaido University\u2019s Faculty of Fisheries Sciences.<\/p>\n<p>Source: <a rel=\"noopener\" href=\"https:\/\/www.sustainability-times.com\/sustainable-business\/bacteria-can-help-us-eliminate-plastic-waste-from-the-seas\/\">Sustainability Times<\/a><\/p>\n<\/div>\n<p>The post <a rel=\"noopener\" href=\"https:\/\/vastuullisuusuutiset.fi\/fi\/environmental-news-en\/2-417\/\">Bacteria can help us eliminate plastic waste from the seas<\/a> appeared first on <a rel=\"noopener\" href=\"https:\/\/vastuullisuusuutiset.fi\/fi\">Vastuullisuusuutiset.fi<\/a>.<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_jetpack_memberships_contains_paid_content":false,"footnotes":""},"categories":[22],"tags":[1127,575,694,1344],"class_list":["post-117777","post","type-post","status-publish","format-standard","hentry","category-news","tag-bacteria","tag-environmental-news-en","tag-plastic","tag-sea"],"jetpack_featured_media_url":"","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/posts\/117777","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/comments?post=117777"}],"version-history":[{"count":0,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/posts\/117777\/revisions"}],"wp:attachment":[{"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/media?parent=117777"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/categories?post=117777"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/tags?post=117777"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
