醋酸菌多相分类研究进展

Research Progress on the Polyphasic Taxonomy of Acetic Acid Bacteria

摘要:

醋酸菌是一大群革兰氏染色阴性、绝对好氧的细菌的总称, 能将乙醇或糖类不完全氧化为有机酸。醋酸菌的分类在近30年经历了很大变化, 早期的分类系统主要以表型和生化特征为基础。如今, 大多采用结合表型、化学分类法和基因型数据的多相分类法对醋酸菌进行分类。本文综述了醋酸菌的多相分类研究进展, 主要介绍了醋酸菌的现行分类情况及表型分类、化学分类和基因分型等方法在醋酸菌分类中的应用。

Abstract:

Acetic acid bacteria are Gram-negative, obligate aerobic bacteria that have the ability to incompletely oxidize alcohols or sugars to organic acids as end products. The taxonomy of acetic acid bacteria has undergone many changes in the last 30 years. The early classification systems for these bacteria were based on morphological and biochemical characteristics. Today, the acetic acid bacteria are classified as the consensus result of a polyphasic analysis, combining phenotypic, chemotaxonomic and genotypic data. This paper reviewed the polyphasic taxonomy of acetic acid bacteria, mainly introduced the current classification of acetic acid bacteria, then discussed the application of phenotypic, chemotaxonomic and genotypic method in the taxonomy of acetic acid bacteria.
