In this work, laccase treatment was employed to enhance nanofiltration process by lignin removal. Results showed that the membrane filterability was increased in terms of deionized water flux and PHL filtration process. On the other hand, the hemicellulosic sugars were negligible affected and can be concentrated to 172 g/L, which was increased about 300% from the original one. The combined laccase-nanofiltration process provides an alternative approach to utilize hemicellulosic sugars of PHL in an environmentally friendly way.
在这项工作中，漆酶处理被用于通过去除木质素来增强纳滤过程。结果表明，在去离子水通量和 PHL 过滤过程方面，膜过滤性能得到了提高。另一方面，半纤维素糖的影响可以忽略不计，并且可以浓缩至 172g/L，比原始浓度提高了约 300%。漆酶-纳滤组合工艺为以环保的方式利用 PHL 的半纤维素糖提供了一种替代方法。
