高温放线菌科最新研究进展

The family Thermoactinomycetaceae－A review

摘要:

摘要: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。

Abstract:

Abstract: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.
