Abstract:
Biosurfactants have garnered increased attention lately due to their superiority of their properties over fossil-derived counterparts. While the cost of production remains a significant hurdle to surpass synthetic surfactants, biosurfactants have been anticipated to gain a larger market share in the coming decades. Among these, glycolipids, a type of low-molecular-weight biosurfactant, stand out for their efficacy in reducing surface and interfacial tension, which made them highly sought-after for various surfactant-related applications. Glycolipids are composed of hydrophilic carbohydrate moieties linked to hydrophobic fatty acid chains through ester bonds that mainly include rhamnolipids, trehalose lipids, sophorolipids, and mannosylerythritol lipids. This review highlights the current landscape of glycolipids and covers specific glycolipid productivity and the diverse range of products found in the global market. Applications such as bioremediation, food processing, petroleum refining, biomedical uses, and increasing agriculture output have been discussed. Additionally, the latest advancements in production cost reduction for glycolipid and the challenges of utilizing second-generation feedstocks for sustainable production are also thoroughly examined. Overall, this review proposes a balance between environmental advantages, economic viability, and societal benefits through the optimized integration of secondary feedstocks in biosurfactant production.
摘要:
生物表面活性剂由于其性质优于化石衍生的对应物而最近引起了越来越多的关注。虽然生产成本仍然是超过合成表面活性剂的重要障碍,预计生物表面活性剂将在未来几十年获得更大的市场份额。其中,糖脂,一种低分子量的生物表面活性剂,因其降低表面和界面张力的功效而脱颖而出,这使得它们在各种表面活性剂相关的应用中备受追捧。糖脂由通过酯键与疏水性脂肪酸链连接的亲水性碳水化合物部分组成,主要包括鼠李糖脂。海藻糖脂质,槐糖脂,和甘露糖赤藓糖醇脂质。这篇综述突出了糖脂的现状,涵盖了特定的糖脂生产率和全球市场上发现的各种产品。应用,如生物修复,食品加工,石油精炼,生物医学用途,并讨论了增加农业产出的问题。此外,还彻底研究了糖脂生产成本降低的最新进展以及利用第二代原料进行可持续生产的挑战。总的来说,这项审查建议在环境优势之间取得平衡,经济可行性,通过在生物表面活性剂生产中优化二次原料的整合和社会效益。
