| 目的 介绍木质纤维素材料的化学组成及结构，综述常见的木质纤维素材料预处理方法及其在合成包装材料聚羟基脂肪酸酯（PHA）方面的应用的研究进展。方法 通过对国内外研究现状和研究成果分析总结，重点论述常见的木质纤维素材料预处理方法蒸汽爆破预处理、热水预处理、酸预处理、碱预处理、氨纤维爆破预处理、离子液体预处理、有机溶剂预处理等对木质纤维素材料糖化率的影响，及其在合成包装材料聚羟基脂肪酸酯（PHA）方面的应用。结果 不同的木质纤维素材料和不同的预处理方法对最终产生的总糖含量及总糖内单糖种类和单糖占总糖质量分数产生很大的影响，其中将不同总 糖（包含不同单糖种类和单糖占总糖的质量分数）作为碳源用于微生物发酵生产PHA，还会使形成 PHA的单体及单体在PHA中的质量分数不同，形成具有不同性质的PHA，能广泛应用到包装领域中。 结论 关于国内外研究优化预处理和酶解工艺提高生成可发酵糖产量的研究有很多，热水预处理技术相较于其他预处理技术具有生产成本低、绿色环保等特点，因此，开发经济性好且适用于大规模工业化生产的热水预处理技术是今后值得关注的重点方向。 |
| 英文摘要: |
| The work aims to introduce the chemical composition and structure of lignocellulosic materials and review the research progress of the common pretreatment methods of lignocellulosic materials and their application in the synthesis of polyhydroxyalkanoates (PHA). Based on the analysis and summary of the research status and achievements at home and abroad, the influence of common pretreatment methods of lignocellulosic materials, such as steam explosion pretreatment, hot water pretreatment, acid pretreatment, alkali pretreatment, ammonia fiber explosion pretreatment, ionic liquid pretreatment, organic solvent pretreatment, etc., on the saccharification rate of lignocellulosic materials and their application in synthetic packaging materials polyhydroxyalkanoates were emphatically discussed. Different lignocellulosic materials and different pretreatment methods had a great influence on the content of total sugar and the type of monosaccharide in total sugar and the mass fraction of monosaccharide in total sugar. Meanwhile, different total sugars (including different monosaccharide types and the mass fraction of monosaccharide in total sugar) were used as carbon source for microbial fermentation to produce PHA, which would form monomer of PHA and different mass fractions of monomer in PHA, thus forming PHA with different properties and widely used in the field of packaging. There are many studies on optimizing pretreatment and enzymolysis technology used to improve the yield of fermentable sugar at home and abroad. Compared with other pretreatment technologies, hot water pretreatment technology is featured by low production cost and environmental protection. Therefore, the development of economic hot water pretreatment technology suitable for large-scale industrial production is the focus of attention in the future. |
