  • Identification of Sesquiterpene Synthases from the Basidiomycota Coniophora Puteana for the Efficient and Highly Selective Β-Co
    Mischko et al. Microb Cell Fact (2018) 17:164 https://doi.org/10.1186/s12934-018-1010-z Microbial Cell Factories RESEARCH Open Access Identifcation of sesquiterpene synthases from the Basidiomycota Coniophora puteana for the efcient and highly selective β‑copaene and cubebol production in E. coli Wolfgang Mischko , Max Hirte , Monika Fuchs , Norbert Mehlmer and Thomas B. Brück* Abstract Background: Terpenes are an important and extremely versatile class of secondary metabolites that are commer- cially used in the pharmaceutical, food and cosmetics sectors. Genome mining of diferent fungal collections has revealed the genetic basis for a steadily increasing number of putative terpene synthases without any detailed knowl- edge about their biochemical properties. The analysis and research of this rich genetic source provides a precious basis for the advancing biotechnological production of an almost endless number of valuable natural metabolites. Results: Three annotated terpene synthases from the little investigated Basidiomycota Coniophora puteana were studied in this work. For biochemical characterization, the heterologous expression in E. coli was conducted leading to the identifcation of two sesquiterpene synthases capable of the highly selective generation of β-copaene and cubebol. These compounds are commercially used as food and favor additives. The new enzymes show the high- est reported product selectivity for their main compounds and therefore represent the frst exclusive synthases for β-copaene (62% product selectivity) and cubebol (75% product selectivity) generation. In combination with an opti- mized heterologous microbial production system, we obtained product titers of 215 mg/L β-copaene and 497 mg/L cubebol. Conclusion: The reported product selectivity and our generated terpene titers exceed all published biotechnological data regarding the production of β-copaene and cubebol.

Besides, inulin is believed to induce certain techno-functional and associated artichoke; fat replacer; properties in food systems. Inulin owing to its foam forming ability has been successfully used as fat hypercholesterolemia; replacer in quite a wide range of products as dairy and baked products.
