Moving away from crude oil to renewable resources for the production of a wide range of compounds is a challenge for future generations. To overcome this, the use of lignocellulose as substrate can contribute to drastically reduce the consumption of crude oil. In this study, sugars from lignocellulose were used as a starting material for the enzymatic synthesis of surface-active sugar esters. The substrates were obtained by an acid-catalyzed, beechwood pretreatment process, which resulted in a fiber fraction that is subsequently hydrolyzed to obtain the monosaccharides. After purification and drying, this glucose- and xylose-rich fraction was used to create a deep eutectic solvent, which acts both as solvent and substrate for the lipase-catalyzed reaction at the same time. Finally, the successful synthesis of glycolipids from a sustainable resource was confirmed by ESI–Q–ToF mass spectrometry and multidimensional NMR experiments. Moreover, conversion yields of 4.8% were determined by LC–MS/MS.

山毛榉碳水化合物用于酶法合成可持续的糖脂。

从原油转向可再生资源以生产多种化合物是对后代的挑战。为了克服这个问题，使用木质纤维素作为底物可以大大减少原油的消耗。在这项研究中，木质纤维素中的糖被用作表面活性糖酯酶促合成的原料。底物是通过酸催化的山毛榉预处理过程获得的，该过程产生了纤维级分，随后将其水解以获得单糖。纯化和干燥后，将这种富含葡萄糖和木糖的馏分用于创建深共晶溶剂，该溶剂同时充当脂肪酶催化反应的溶剂和底物。最后，ESI-Q-ToF质谱和多维NMR实验证实了从可持续资源成功合成糖脂。此外，LC-MS / MS测定的转化率为4.8％。
