摘要： The present invention relates to a recombinant microorganism comprising one or more nucleotide sequence(s) encoding: a polypeptide having ent-copalyl pyrophosphate synthase activity; a polypeptide having ent-Kaurene synthase activity; a polypeptide having ent-Kaurene oxidase activity; and a polypeptide having kaurenoic acid 13-hydroxylase activity, whereby expression of the nucleotide sequence(s) confer(s) on the microorganism the ability to produce at least steviol. The recombinant microorganism may also be capable of expressing one or more UDP-glucosyltransferases such that the microorganism is capable of producing one or more steviol glycosides.

摘要： The present invention relates to the use of a thermophilic nuclease for degrading nucleic acids in vivo and/or in situ, wherein the thermophilic nuclease is heterologous to the host cell and is produced by the host rather than being added exogenously. The present invention further relates to a genetically modified cell which was produced according to the above method. The present invention is particularly beneficial in inactivating the biological activity of recombinant DNA in biomass or biomass-derived products.
