| 中文摘要: |
| 本研究利用酒糟酶解液驱动康普茶菌在河道淤泥（SP）表面原位构建细菌纤维素（BC）网络，以制备一种绿色、低成本的造纸填料，并考察了其在纸张中的应用效果。结果表明，酒糟酶解液培养基制备复合填料（EW-BC/SP）的BC负载量达109.1 mg/g，表现出优异的BC负载能力，原位改性效果优于传统培养基（68.6 mg/g）。当加填量为40%时，纸张中EW-BC/SP的留着率高达88.2%，显著优于SP组（54.7%）；所制加填纸张的抗张指数达31.2 N·m/g，较SP组提高了30.6%，而其耐破指数达1.81 kPa·m²/g，与SP组基本一致，显示出BC网络的显著增强效果。 |
| Abstract: |
| In this study， enzymatic hydrolysate of distiller’s grains was used to drive kombucha bacteria to in-situ construct bacterial cellulose (BC) networks on the surface of river silt， to prepare a green and low-cost papermaking fillers， and investigating its application effect in paper. The results showed that the composite filler (EW-BC/SP) prepared with the distiller’s grains enzymatic hydrolysate medium achieved a BC loading of 109.1 mg/g， exhibiting an excellent BC loading capacity with superior in-situ modification performance compared with the traditional medium group (68.6 mg/g). When the filler dosage was fixed at 40%， the retention rate of EW-BC/SP in paper reached as high as 88.2%， which was significantly higher than that of SP group (54.7%). The tensile index of the paper added EW-BC/SP reached 31.2 N·m/g， which was 30.6% higher than that of SP group， and the burst index was 1.81 kPa·m²/g， showing basically no difference from SP group， and demonstrated the remarkable enhancement effect of the BC network. |
