摘要

甘蔗渣(SCB)是制糖业的副产品，每年生产约19亿吨。制糖业在甘蔗制糖过程中产生了大量的甘蔗渣，对环境产生了负面影响，引发了环境污染。本研究采用酸水解法从甘蔗渣中提取化学纯化的纤维素(CPC)和纤维素纳米晶体(cnc)。所制备的cnc具有棒状结构，直径在2 ~ 7 nm之间，可用于制备CNC-ZnS纳米复合材料。通过琼脂孔扩散法对CNC-ZnS纳米复合材料进行了进一步的抗菌研究。利用多种分析技术对合成材料进行了表征。结果表明，CNC-ZnS纳米复合材料具有增强的抗菌性能。

CELLULOSE NANOCRYSTALS FROM SUGARCANE BAGASSE: ISOLATION, CHARACTERIZATION AND APPLICATION

"Sugarcane bagasse (SCB) is a by-product of the sugar industry, with approximately 1.9 billion tonnes produced yearly. The sugar industry produces a huge quantity of bagasse during the manufacture of sugar from sugarcane, which has a negative environmental impact, triggering environmental pollution. In this work, chemically purified cellulose (CPC) and cellulose nanocrystals (CNCs) were very effectively extracted from sugarcane bagasse by the acid-hydrolysis method. The obtained CNCs had a rod-like shape, with a diameter in the range of 2-7 nm, and were used to form a CNC-ZnS nanocomposite. The CNCs were seen to be less agglomerated, and the CNC-ZnS nanocomposite was further tested in an antibacterial study using the agar well diffusion method. The synthesized materials were characterized using a number of analytical techniques. The results demonstrated an enhanced antibacterial property of the CNC-ZnS nanocomposite."
