木聚糖酶分子改造及工业应用研究现状

Present Status of Molecular Modification and Industrial Application of Xylanase

每个蛋白酶分子都有其相对应的最适反应温度和pH以及保持其稳定性的温度和pH。其中最适温度和pH共同决定了其应用领域,而对温度和酸碱性的稳定程度决定其是否具有商业化生产前景。在科技进步和社会需求相互推进的背景下,酶制剂领域也随时代的节奏蓬勃发展。人工改造技术使得每个天然酶分子保留其原有优势特性的同时向着更适合社会生产需要的方向转化,从而开辟出了更广阔的应用范围,创造出更大的商业价值,推动社会和人类的进步。文章从木聚糖酶的生化特性着手介绍,进而阐述常用的分子改造手段及木聚糖酶的主要应用成果。

Each enzyme molecule has its corresponding optimum reaction temperature, pH and the tolerance stability of temperature and pH. The optimum temperature and pH determines its application domain and it scommercial prospect depends on the degree of stability of temperature and the acid or alkaline. Under the background of scientific and technological progress and social needs improvement, enzyme areas thrives rapidly. Artificial modification technology made each natural enzyme molecules retain its original properties and transform to suit for the need of social production, thereby opened up a wider range of applications, created greater commercial value and promoted the progress of the society and human. This paper started from the biochemical features of xylanase and then talked about com- mon molecular modification method, finally summarized the main application of xylanase.
