  Provided are methods of producing 2,5-furandicarboxylic acid (FDCA) from renewable sources such as seaweed, alginate, oligoalginate, pectin, oligopectin, polygalacturonate, galacturonate, and/or oligogalacturonate. The sugars in the renewable sources can be converted into one or more intermediates such as 4-deoxy-L-erythro-5- hexoseulose uronate (DEHU), 4-deoxy-L-threo-5-hexosulose uronate (DTHU), 5- hydroxymethyl furfural (HMF), 2,5-dihydroxymethyl furan (DHMF), and 5-formyl-2- furancarboxylic acid (FFA), which can be converted into FDCA by dehydration and cyclization to produce 5-formyl-2-furancarboxylic acid (FFA), followed by oxidation to produce FDCA. DEHU or DTHU may also be converted into FDCA by oxidation to produce 2,3-dihydroxy-5-oxohexanedioic acid (DOHA), which then undergoes dehydration and cyclization to produce FDCA.

  提供的方法可以从可再生资源如海藻、藻酸盐、寡聚藻酸盐、果胶、寡聚果胶、多聚半乳糖酸、半乳糖酸和/或寡聚半乳糖酸中生产2,5-呋喃二甲酸（FDCA）。可再生资源中的糖可以转化为一个或多个中间体，如4-脱氧-L-红鼻子-5-己糖醛酸（DEHU）、4-脱氧-L-反-5-己糖醛酸（DTHU）、5-羟甲基糠醛（HMF）、2,5-二羟甲基呋喃（DHMF）和5-甲酰基-2-呋喃羧酸（FFA），通过脱水和环化转化为5-甲酰基-2-呋喃羧酸（FFA），然后氧化产生FDCA。DEHU或DTHU也可以通过氧化转化为2,3-二羟基-5-氧代己二酸（DOHA），然后进行脱水和环化产生FDCA。
