Abstract:In recent years, great attentions have been paid to marine actinomycetes for their ability to synthesize new metabolites. Some of the synthesized metabolites with new lead structures have demonstrated great potential to be developed as new drugs. This situation has also prompted the development of marine actinomycetes research in China. This review mainly discusses the latest advances regarding Marinactinospora thermotolerans research in terms of the taxonomy, the discovery of novel metabolites, their biosynthesis mechanisms, and the species genome analytical results, etc. M. thermotolerans is considered to be a good model of marine actinobacteria for mining resource research in future.
