益生乳酸菌遗传稳定性研究进展

Genetic stability of probiotic lactic acid bacteria-A review

益生乳酸菌因为与人类健康息息相关而日益备受关注。时至今日,益生乳酸菌衍生制品已发展成为时尚养生领域的新宠儿。对于准备进入生产流通环节的益生乳酸菌,除需具有优异的益生特性,还应具有良好的稳定性。本文拟从遗传稳定性的研究方法出发,结合其国内外的研究进展作一综述,旨在为同行提供一些参考。

Growing attention has been focused on probiotic lactic acid bacteria because of their important health-promoting effects. Nowadays, probiotic-based products have become fashionable nutraceuticals of choice. Before a newly developed probiotic-based product is to be introduced into the industry, it is important to ensure not only the desirable properties of the probiotic strain but also a good genetic stability. This article firstly introduces the research methods for investigating genetic stability, followed by summarizing the latest research progress in China and overseas.
