This work discussed the preparation of Ag nanoparticles (AgNPs) and AgNPs impregnated sub-micrometer crystalline jute cellulose (SCJC) particles using a green synthetic bioreduction method. The ultimate nanocomposite particles were named as SCJC/Ag. The crystalline structure of AgNPs was maintained in SCJC/Ag nanocomposte particles. The catalytic efficiency of SCJC/Ag nanocomposite particles were evaluated for the degradation of congo red (CR) and methylene blue (MB) using NaBH4 as reducing agent. A complete degradation of 20 mL of each CR (0.1 mM) and MB (0.05 mM) dye solution was achieved within 14 min when 0.005 mg mL-1 of SCJC/Ag nanocomposite particles was employed. SCJC/Ag nanocomposite particles also exhibited moderate antibacterial activities against Staphylococcus aureus, Escherichia coli, Shigella dysenteriae and Shigella boydii and the results were comparable with those of the reference AgNPs. SCJC/Ag nanocomposite particles were the most effective against Escherichia coli (E. coli) with minimum inhibitory concentration of 0.014 mg mL-1.

银浸渍的亚微米级结晶黄麻纤维素颗粒：催化和抗菌性能。

这项工作讨论了使用绿色合成生物还原法制备银纳米颗粒（AgNPs）和浸渍亚微米级结晶黄麻纤维素（SCJC）的AgNPs。最终的纳米复合颗粒被命名为SCJC / Ag。AgNPs的晶体结构保持在SCJC / Ag纳米复合颗粒中。使用NaBH4作为还原剂，评估了SCJC / Ag纳米复合颗粒对刚果红（CR）和亚甲基蓝（MB）降解的催化效率。当使用0.005 mg mL-1的SCJC / Ag纳米复合颗粒时，在14分钟内可以完全降解20 mL的每种CR（0.1 mM）和MB（0.05 mM）染料溶液。SCJC / Ag纳米复合颗粒还对金黄色葡萄球菌，大肠杆菌，痢疾志贺氏菌和博伊氏志贺氏菌，其结果与参考AgNPs相当。SCJC / Ag纳米复合颗粒对大肠杆菌（E. coli）的抑制作用最强，最小抑制浓度为0.014 mg mL-1。
