Biodegradable plastics based on biomass-derived compounds are attracting attention as an alternative to conventional plastics, and Osaka Metropolitan University scientists have now synthesized biodegradable nylon precursors.<\/p>\n\n\n\n<p>Professor Yutaka Amao\u2019s team at the Research Center for Artificial Photosynthesis previously reported on a method for producing raw materials for biodegradable plastics from biomass-derived compounds. A polyester-type biodegradable plastic could be formed by using L-lactic acid as the raw material for polylactic acid.<\/p>\n\n\n\n<p>This time, by using L-alanine, an amino acid with a similar structure, the team created raw material for a nylon-type biodegradable plastic. Artificial photosynthesis technology was developed with the addition of the biocatalyst L-alanine dehydrogenase, which combines ammonia with pyruvate to produce L-alanine, to the photoredox system composed of a dye and a catalyst.<\/p>\n\n\n\n<p>\u201cWe have also succeeded in synthesizing the precursor of biodegradable nylon poly-L-alanine using solar energy,\u201d Professor Amao declared. \u201cIn the future, we hope to achieve the synthesis of nylon precursors that have a low impact on the environment, with the aim of producing L-alanine through artificial photosynthesis using ammonia derived from biomass compounds.\u201d<\/p>\n\n\n\n<p>The findings were published in&nbsp;<em>Sustainable Energy &amp; Fuels<\/em>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Nylon, a durable and elastic material, is like other plastics made from chemicals found in fossil fuels. <\/p>\n","protected":false},"author":2,"featured_media":25656,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[17],"tags":[],"class_list":["post-25655","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-research"],"featured_image_urls":{"full":["https:\/\/www.revoscience.com\/en\/wp-content\/uploads\/2025\/01\/photoredox-system.jpg",738,321,false],"thumbnail":["https:\/\/www.revoscience.com\/en\/wp-content\/uploads\/2025\/01\/photoredox-system-200x200.jpg",200,200,true],"medium":["https:\/\/www.revoscience.com\/en\/wp-content\/uploads\/2025\/01\/photoredox-system-675x294.jpg",675,294,true],"medium_large":["https:\/\/www.revoscience.com\/en\/wp-content\/uploads\/2025\/01\/photoredox-system.jpg",738,321,false],"large":["https:\/\/www.revoscience.com\/en\/wp-content\/uploads\/2025\/01\/photoredox-system-675x294.jpg",675,294,true],"1536x1536":["https:\/\/www.revoscience.com\/en\/wp-content\/uploads\/2025\/01\/photoredox-system.jpg",738,321,false],"2048x2048":["https:\/\/www.revoscience.com\/en\/wp-content\/uploads\/2025\/01\/photoredox-system.jpg",738,321,false],"ultp_layout_landscape_large":["https:\/\/www.revoscience.com\/en\/wp-content\/uploads\/2025\/01\/photoredox-system.jpg",738,321,false],"ultp_layout_landscape":["https:\/\/www.revoscience.com\/en\/wp-content\/uploads\/2025\/01\/photoredox-system.jpg",738,321,false],"ultp_layout_portrait":["https:\/\/www.revoscience.com\/en\/wp-content\/uploads\/2025\/01\/photoredox-system-600x321.jpg",600,321,true],"ultp_layout_square":["https:\/\/www.revoscience.com\/en\/wp-content\/uploads\/2025\/01\/photoredox-system-600x321.jpg",600,321,true],"newspaper-x-single-post":["https:\/\/www.revoscience.com\/en\/wp-content\/uploads\/2025\/01\/photoredox-system.jpg",738,321,false],"newspaper-x-recent-post-big":["https:\/\/www.revoscience.com\/en\/wp-content\/uploads\/2025\/01\/photoredox-system-550x321.jpg",550,321,true],"newspaper-x-recent-post-list-image":["https:\/\/www.revoscience.com\/en\/wp-content\/uploads\/2025\/01\/photoredox-system-95x65.jpg",95,65,true],"web-stories-poster-portrait":["https:\/\/www.revoscience.com\/en\/wp-content\/uploads\/2025\/01\/photoredox-system.jpg",640,278,false],"web-stories-publisher-logo":["https:\/\/www.revoscience.com\/en\/wp-content\/uploads\/2025\/01\/photoredox-system.jpg",96,42,false],"web-stories-thumbnail":["https:\/\/www.revoscience.com\/en\/wp-content\/uploads\/2025\/01\/photoredox-system.jpg",150,65,false]},"author_info":{"info":["RevoScience"]},"category_info":"<a href=\"https:\/\/www.revoscience.com\/en\/category\/news\/research\/\" rel=\"category tag\">Research<\/a>","tag_info":"Research","comment_count":"0","_links":{"self":[{"href":"https:\/\/www.revoscience.com\/en\/wp-json\/wp\/v2\/posts\/25655","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.revoscience.com\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.revoscience.com\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.revoscience.com\/en\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.revoscience.com\/en\/wp-json\/wp\/v2\/comments?post=25655"}],"version-history":[{"count":1,"href":"https:\/\/www.revoscience.com\/en\/wp-json\/wp\/v2\/posts\/25655\/revisions"}],"predecessor-version":[{"id":25657,"href":"https:\/\/www.revoscience.com\/en\/wp-json\/wp\/v2\/posts\/25655\/revisions\/25657"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.revoscience.com\/en\/wp-json\/wp\/v2\/media\/25656"}],"wp:attachment":[{"href":"https:\/\/www.revoscience.com\/en\/wp-json\/wp\/v2\/media?parent=25655"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.revoscience.com\/en\/wp-json\/wp\/v2\/categories?post=25655"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.revoscience.com\/en\/wp-json\/wp\/v2\/tags?post=25655"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
