Many microorganisms that can do this have already been found, but they can usually only work at temperatures above 30C (86F). This means that using them in industrial practice is prohibitively expensive because of the heating required. It also means using them is not carbon neutral. Scientists from the Swiss Federal Institute WSL have found microbes that can do this at 15C, which could lead to a breakthrough in microbial recycling. Their findings have been published in the journal Frontiers in Microbiology.<\/p>\n<p>Dr Joel R\u00fcthi from WSL and colleagues sampled 19 strains of bacteria and 15 of fungi growing on free-lying or intentionally buried plastic kept in the ground for one year in Greenland, Svalbard and Switzerland. They let the microbes grow as single-strain cultures in the laboratory in darkness at 15C and tested them to see if they could digest different types of plastic. The results showed that the bacterial strains belonged to 13 genera in the phyla actinobacteria and proteobacteria, and the fungi to 10 genera in the phyla ascomycota and mucoromycota.<\/p>\n<p>The plastics tested included non-biodegradable polyethylene (PE) and the biodegradable polyester-polyurethane (PUR) as well as two commercially available biodegradable mixtures of polybutylene adipate terephthalate (PBAT) and polylactic acid (PLA). None of the strains were able to digest PE, even after 126 days of incubation on these plastics. But 19 strains (56%), including 11 fungi and eight bacteria, were able to digest PUR at 15C, while 14 fungi and three bacteria were able to digest the plastic mixtures of PBAT and PLA.<\/p>\n<p>Source: <a rel=\"noopener\" href=\"https:\/\/www.theguardian.com\/science\/2023\/may\/10\/microbes-digest-plastics-low-temperatures-recycling\">Guardian<\/a><\/p>\n<\/div>\n<p>The post <a rel=\"noopener\" href=\"https:\/\/vastuullisuusuutiset.fi\/fi\/environmental-news-en\/microbes-discovered-that-can-digest-plastics-at-low-temperatures\/\">Microbes discovered that can digest plastics at low temperatures<\/a> appeared first on <a rel=\"noopener\" href=\"https:\/\/vastuullisuusuutiset.fi\/fi\">Vastuullisuusuutiset.fi<\/a>.<\/p>","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":[7772,575,1180,694],"class_list":["post-114186","post","type-post","status-publish","format-standard","hentry","category-news","tag-digestion","tag-environmental-news-en","tag-microbes","tag-plastic"],"jetpack_featured_media_url":"","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/posts\/114186","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/comments?post=114186"}],"version-history":[{"count":0,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/posts\/114186\/revisions"}],"wp:attachment":[{"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/media?parent=114186"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/categories?post=114186"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/tags?post=114186"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
