The current commercial plastic manufactures have been produced using petroleum-based resource. However, due to concerns over the resource depletion and the environmental sustainability, bioresource-based manufacturing processes have been developed to cope against these concerns. Bioresource-derived 2,5-furandicarboxylic acid (FDCA) can be utilized as a building block material for plastic manufactures. To date, numerous technologies have been developed for the production of FDCA using various types of bio-based feedstocks such as hydroxymethylfurfural (HMF), 6-C sugars, and polysaccharides. The commercial companies produce FDCA using HMF-based production processes due to their high production efficiency, but the high price of HMF is a problem bottleneck. Our review affords important information on breakthrough approaches for the cost-efficient and sustainable production of FDCA using raw plant feedstocks rich in inulin. These approaches include bioprocessing technology based on the direct use of raw plant feedstocks and biomodification of the target plant sources. For the former, an ionic liquid-based processing system is proposed for efficient pretreatment of raw plant feedstocks. For the latter, the genes encoding the key enzymes; sucrose:sucrose 1-fructoyltransferase (1-SST), fructan:fructan 1-fryuctosyltransferase (1-FFT), fructan 1-exohydrolase (1-FEH), and microbe-derived endoinulinase, are introduced for biomodification conducive to facilitating bioprocess and improving inulin content. These approaches would contribute to cost-efficiently and sustainably producing bio-based FDCA.

将富含菊粉的植物生物质转化为 2,5-呋喃二甲酸 (FDCA):生物可再生塑料的进展与挑战

目前的商业塑料制品是使用石油资源生产的。然而,由于对资源枯竭和环境可持续性的担忧,已经开发了基于生物资源的制造工艺来应对这些担忧。生物资源衍生的 2,5-呋喃二甲酸 (FDCA) 可用作塑料制造的积木材料。迄今为止,已经开发了多种技术来使用各种类型的生物基原料如羟甲基糠醛 (HMF)、6-C 糖和多糖生产 FDCA。由于生产效率高,商业公司使用基于 HMF 的生产工艺生产 FDCA,但 HMF 的高价格是一个问题瓶颈。我们的评论提供了关于使用富含菊粉的原始植物原料以具有成本效益和可持续的方式生产 FDCA 的突破性方法的重要信息。这些方法包括基于直接使用原始植物原料的生物加工技术和目标植物来源的生物改性。对于前者,提出了一种基于离子液体的处理系统,用于有效预处理植物原料。对于后者,编码关键酶的基因;蔗糖:蔗糖 1-果糖基转移酶 (1-SST)、果聚糖:果聚糖 1-果糖基转移酶 (1-FFT)、果聚糖 1-外切水解酶 (1-FEH) 和微生物来源的菊粉内切酶,用于生物改性,有助于促进生物过程和改善菊粉含量。这些方法将有助于经济高效且可持续地生产基于生物的 FDCA。
