紫外光谱分析结果表明循环式液 液萃取器可有效抽提富集微量木素生物降解物质 ,抽提物通过气相色谱 质谱联用仪鉴定出 40余种木素生物降解相关物质组分 ,不同结构木素经不同酶处理后其降解产物组成及含量有显著差异 .为木素生物降解机制研究提供了一种新方法 .
The result of UV spectrum shows that the circulating liquid-liquid extractor can effectively extract and enrich the micro-lignin biodegradable material. Extracts of more than 40 kinds of lignin biodegradation related substances are identified by gas chromatograph-mass spectrometry. Different structures The composition and content of degradation products of lignin treated by different enzymes were significantly different, which provided a new method for the study of lignin biodegradation mechanism.
