    摘要: A method for producing (-)trans-2, 3-epoxysuccinic acid, which can be used as a good starting material for the sythesis of optically active compounds such as optically specific single .beta.-lactam antibiotics, characterized in that filamentous fungi capable of producing (-)trans-2,3-epoxysuccinic acid are cultured in liquid medium while either ammonia, sodium hydroxide or potassium hydroxide is added to maintain the culture medium in a pH range of 5.0 to 7.5 throughout the culturing period.

    摘要: The present invention provides a method of producing lysergic acid and other ergot alkaloids by genetic modification of a fungus. A strain of fungus comprising Aspergillus fumigatus (A. fumigatus) and expressing one or more genes of the ergot alkaloid biosynthesis pathway from one or more fungus selected from the group consisting of Epichloë festucae var. lolii×Epichloë typhina isolate Lp1 (E. sp. Lp1); Claviceps species; Claviceps africana (C. africana); Claviceps gigantea (C. gigantea); Epichloë coenophiala and Periglandula species, wherein gene easA or gene easM is inactivated in said A. fumigatus, is provided.
