摘要: 亚麻是中国重要的经济作物,为了提高亚麻原茎脱胶的效率,在利用PCR-DGGE技术研究亚麻茎杆上菌群多样性的基础上,对其最优电泳条件进行了优化。结果表明:当使用经胶回收后的样品进行PCR-DGGE,电泳时间为200~220 min,变性凝胶梯度为25%~55%,固定时间为12~15 min,染色时间为20 min,显影时间为5~10 min时,得到电泳和分离效果最好。本研究通过优化DGGE电泳条件,可以更加清晰的得到沤麻过程中细菌的多样性,该工作对利用PCR-DGGE技术研究亚麻茎秆菌群多样性提供了方法基础。

Abstract: Flax is an important economic crop in China. In order to improve the efficiency of retting, the authors used PCR-DGGE technique to study the flax stem microflora diversity, and optimized the best condition of this method. The results showed that, when PCR-DGGE was carried out using the gel recycling samples, the electrophoresis time was 200-220 min, modified gel gradient was 25%-55%, fixed time was about 12-15 min, dyeing time was 20 min, developing time was 5-10 min, the electrophoresis and separation results were good. The study clearly obtained the bacteria diversity in flax retting by optimizing the electrophoresis condition of DGGE. It could set a base for the use of PCR-DGGE to study the microflora community diversity of flax stem.
