高温放线菌科最新研究进展小型综述

The family Thermoactinomycetaceae-A review

高温放线菌科(Thermoactinomycetaceae)是一个古老而又年轻的微生物类群。目前其分类地位为:细菌域(Domain Bacteria),厚壁菌门(Phylum Firmicutes),芽孢杆菌纲(Class Bacilli),芽孢杆菌目(Order Bacillales),高温放线菌科。经过一个多世纪,尤其是近十年广泛而深入地研究,该类群已拓展到14个属25个种。这些资源广泛分布在陆生性热泉、高温大曲、堆肥、稻草、甘蔗渣等高温场所,同时在海洋沉积物和临床来源也有发现,该类群微生物有抗性的内生孢子可在土壤、水或海洋基质中存活。高温放线菌科具有较大的药物开发和工业应用潜力,因此得到学者的广泛关注。本文综述了高温放线菌科的分类学研究进展与生态多样性,并介绍了其在药物开发和工业生产中的应用潜力。

Thermoactinomycetaceae is a new and old prokaryotic group. The present taxonomic status is： Domain Bacteria, Phylum Firmicutes, Class Bacilli, Order Bacillales, Family Thermoactinomycetaceae. Study on this family is going on more than a century. Until now, this family comprises of 14 genera and 25 species. Members of the family Thermoactinomycetaceae are widely distributed in the terrestrial hot springs, high-temperature Daqu （a starter culture for Chinese alcohol fermentation） , compost, straw, bagasse and other places of high temperature, and marine sediments. The drug-resistance spores can survive in soil, water for long time. They also have great potential in both industrial and drug development, So they got a wide attention by scholars. This paper reviews the research progress of taxonomical studies and ecological diversity of the family Thermoactinomycetaceae, also introduces their potential applications in drug development and industrial production.
