ABSTRACT
Forskolin is a complex labdane plant diterpenoid, which has been used in the treatment of a variety of diseases based on its activity as an activator of adenosine monophosphate(cAMP) cyclase. Natural forskolin exists only in the cork layer of the root of Coleus forskohlii. Due to the complexity of the extraction and chemical synthesis processes, the yield and purity of forskolin cannot meet commercial requirements. In recent years, with the rapid development of synthetic biology and the analysis and interpretation of many diterpene biosynthetic pathways, a new approach has been provided for the green production of forskolin. In this paper, the structure, activity, biosynthetic pathway and the heterologous biosynthesis of forskolin were reviewed. The problems and solutions in the heterologous biosynthesis of forskolin were also discussed and summarized, which will provide references for the construction of high-yielding forskolin engineering strains.

The focus of microbiologists has moved to the rare actinomycetes.For selective isolation of rare actinomycetes that all play the important role in bioactive compounds,the approaches which involve the methods using gellan gum and flooding solution、 rehydration-centrifugation(RC)、 extremely high frequency radiation(EHF)、 bacteriophage and sucrose-gradient centrifugation were introduced in this paper.
