地嗜皮菌科放线菌的研究进展

Recent advance in Geodermatophilaceae－A review

摘要:

摘要:地嗜皮菌科(Geodermatophilaceae)是放线菌中一个年轻的分类单元。早在1996年Normand曾提出过地嗜皮菌科，但一直未能得到公认;直到2006年，Normand综合了地嗜皮菌属(Geodermatophilus)、芽生球菌属(Blastococcus)和贫养杆菌属(Modestobacter)等3个属的共同特征，全面概括了地嗜皮菌科的典型特征，终于使地嗜皮菌科被正式编入放线菌的一个科。到目前为止，地嗜皮菌科涵盖了地嗜皮菌属、芽生球菌属和贫养杆菌属等3个属共25个有效描述种。地嗜皮菌科菌株被视为极端环境的先锋生物之一，在抗逆机制研究、沙漠治理、环境修复等方面初现优势。本文就地嗜皮菌科的建立、分类学特征、科内各属的研究现状、以及它们在生态学与应用研究方面的进展和前景进行了综述。

Abstract:

Abstract:The family Geodermatophilaceae is a newly established actinobacterial taxon．Normand ever proposed the family Geodermatophilaceae in 1996，which was recognized as an invalid taxon at that time．In 2006，based on the common characteristics of the genera Geodermatophilus， Blastococcus and Modestobacter，Normand summarized the typical characteristics of Geodermatophilaceae，then the family Geodermatophilaceae was finally accommodated as a validly described taxon in the phylum Actinobacteria．Up to date，the family Geodermatophilaceae consisted of 3 genera，i.e.，Geodermatophilus，Blastococcus and Modestobacter，including 25 validly described species．The members of the family Geodermatophilaceae were considered as biologic pioneers in extreme environments，exhibiting many potential advantages in the study of mechanism of stress resistance，desertification control and environmental remediation．The objective of this review is to summarize the research advances in the family Geodermatophilaceae，including the establishment and taxonomic characteristics of the family，as well as their application prospect and the roles in the field of ecology.
