Abstract:
Sugarcane industry is a major agricultural sector capable of producing sugars with byproducts including straw, bagasse, and molasses. Sugarcane byproducts are no longer wastes since they can be converted into carbon-rich resources for biorefinery if pretreatment of these is well established. Considerable efforts have been devoted to effective pretreatment techniques for each sugarcane byproduct to supply feedstocks in microbial fermentation to produce value-added fuels, chemicals, and polymers. These value-added chains, which start with low-value industrial wastes and end with high-value products, can make sugarcane-based biorefinery a more viable option for the modern chemical industry. In this review, recent advances in sugarcane valorization techniques are presented, ranging from sugarcane processing, pretreatment, and microbial production of value-added products. Three lucrative products, ethanol, 2,3-butanediol, and polyhydroxyalkanoates, whose production from sugarcane wastes has been widely researched, are being explored. Future studies and development in sugarcane waste biorefinery are discussed to overcome the challenges remaining.
摘要:
甘蔗工业是一个主要的农业部门,能够生产包括秸秆在内的副产品糖,甘蔗渣,和糖蜜.甘蔗副产品不再是废物,因为如果对其进行预处理,它们可以转化为富含碳的资源用于生物精炼。相当大的努力已经致力于有效的预处理技术的每一个甘蔗副产品供应原料在微生物发酵生产增值燃料,化学品,和聚合物。这些增值链,以低价值的工业废物开始,以高价值的产品结束,可以使基于甘蔗的生物炼制成为现代化学工业更可行的选择。在这次审查中,介绍了甘蔗增值技术的最新进展,从甘蔗加工,预处理,和微生物生产增值产品。三个利润丰厚的产品,乙醇,2,3-丁二醇,和聚羟基链烷酸酯,其从甘蔗废料中生产的产品已经得到了广泛的研究,正在探索。讨论了甘蔗废物生物炼制的未来研究和发展,以克服剩余的挑战。
