摘要:

食品中的很多微生物无法分离培养,传统的微生物研究方法不仅费时费力,而且会造成偏差。变性梯度凝胶电泳(denaturing gradient gel electrophoresis,DGGE)是一种不依赖于纯培养的分子技术,因其快速、灵敏、分析全面等特点已被广泛应用于微生物生态学的研究中。本文介绍了DGGE 的发展历程、原理、操作步骤及其在食品微生物研究中的进展,评价了该技术的优势和局限性,展望了其在食品领域内的应用前景。

关键词: 食品微生物, 变性梯度凝胶电泳(DGGE), 微生物多样性

Abstract:

There are lots of unknown and “unculturable” microorganisms in food, but traditional microbiological methods not only are labor-intensive and time-consuming, but may cause deviation. Denaturing gradient gel electrophoresis (DGGE) is a cultural-independent molecular technique, and has been recently introduced into food microbial ecology. DGGE could easily identify the microorganisms from food, avoiding the potential deviation of traditional methods. This review summarized the development, concept, principle, operation procedure of DGGE and its application in food and food-related ecosystems. The limitation and application prospect of this approach in food microbiology were also discussed.

Key words: food microorganism, denaturing gradient gel electrophoresis (DGGE), microbial diversity
