Claims24
A strain of Claviceps purpurea (Fr.) Tul., that produces an amount of beta-ergokryptine greater than the amount of alpha-ergokryptine during parasitic growth on a cereal.
A strain of Claviceps purpurea (Fr.) Tul., that has been deposited according to The Budapest Treaty in the International depositary authority Czech Collection of Microorganisms (CCM) at the Masaryk University, Tvrdého 14, Brno, Czech Republic under Accession Number CCM 8360.
A strain of Claviceps purpurea (Fr.) Tul., that produces sclerotia containing a high content of ergot peptide alkaloids relative to CCM F-721.
A strain of Claviceps purpurea derived from strain CCM F-721 having an average content of ergot peptide alkaloids that is higher than that present in CCM F-721.
A method for producing a mutant of CCM F-721 that produces a content of ergot peptide alkaloids higher than CCM F-721, and/or a higher amount of beta-ergokryptine than alpha-ergokryptine, comprising mutagenizing CCM F-721, thus producing a mutant of CCM F-721, and determining whether the mutant produces a content of ergot alkaloids higher than CCM F-721, and/or a higher amount of beta-ergokryptine than alpha-ergokryptine.
