摘要

本研究介绍了一种新型的可回收的酒石酸/酒石酸钠（TA/ST）缓冲系统，以解决竹生物质生产低聚木糖（XOS）的挑战：减少木糖副产品并使TA再利用。在优化条件下（60 mM TA/ST，摩尔比8.0,170℃，30 min）， TA/ST体系的XOS产率达到50.0%，比仅TA水解的XOS产率提高43.6%，木糖产率降低8.5%。通过双极膜电渗析，酒石酸回收率为78.6%。最后，通过纤维素酶水解脱木质素竹渣，获得了97.7%的高葡萄糖收率。这种方法为XOS生产提供了一种高效、可持续的途径，促进了生态友好型生物炼制实践。

A Novel Tartaric Acid/Sodium Tartrate Buffer System for Xylo-Oligosaccharide Production from Moso Bamboo.

This study introduces a novel and recyclable tartaric acid/sodium tartrate (TA/ST) buffer system to address challenges in xylo-oligosaccharide (XOS) production from bamboo biomass: minimizing xylose byproducts and enabling TA reuse. Under optimized conditions (60 mM TA/ST, molar ratio 8.0, 170 °C, 30 min), the TA/ST system achieved 50.0% XOS yield, surpassing TA-only hydrolysis by enhancing XOS production 43.6% and reducing xylose production by 8.5%. Additionally, 78.6% tartaric acid was recovered via bipolar membrane electrodialysis. Finally, a high glucose yield of 97.7% was obtained from the delignified bamboo residue by cellulase hydrolysis. This approach provides an efficient, sustainable pathway for XOS production, advancing eco-friendly biorefinery practices.
