Production of peptide ergot alkaloids in submerged culture by three isolates of Claviceps purpurea.
Three strains of Claviceps purpurea (Fr.) Tul., isolated from sclerotia grown on rye, produce under submerged conditions ergocryptine and ergotamine, ergocornine and ergosine, and ergocristine, respectively. All of the strains either lacked the ability to produce conidia or formed them sparingly, but they accumulated large quantities of lipids and sterols. The fermentations are typically divide...
متن کاملThe history of ergot of rye (Claviceps purpurea) III: 1940-80.
The period 1940-80 in the history of ergot was dominated by two investigators, Arthur Stoll and Albert Hofmann. There was great excitement when their group isolated from ergot preparations the powerful psychotropic agent lysergic acid diethylamide (LSD).

متن کاملThe history of ergot of rye (Claviceps purpurea) II: 1900-1940.
Ergot, in 1900, was a 'chemical mess'. Henry Wellcome, the pharmaceutical manufacturer, invited Henry Hallett Dale, a physiologist, to join his research department and solve this problem. Dale, in turn, recruited an outstanding group of scientists, including George Barger, Arthur Ewins and Harold Dudley, who would make distinguished contributions not only to the chemistry of ergot but also to t...
متن کاملAssociation of insects and ergot (Claviceps purpurea) in Kentucky bluegrass seed production fields.
Insects in Kentucky bluegrass seed production fields in Oregon, Idaho, and Washington were sampled just before harvest and their association with ergot conidia of Claviceps purpurea Fr. (Tul.) was evaluated during 1996-1998. A diversity of insects was observed at all three locations. The most abundant beneficial insects collected with sweep nets were Nysium spp., Nabis spp., ichneumonid wasps, ...
متن کاملThe history of ergot of rye (Claviceps purpurea) I: from antiquity to 1900.
This article outlines the history of ergot of rye up to 1900. Ergot is a fungal disease that affects many grasses but is particularly damaging to rye. It occurs as the result of an infection by the parasitic organism Claviceps purpurea, which produces characteristic black spurs on the grass. When incorporated into grain, the ergot fungus can cause severe outbreaks of poisoning in humans called ...
