M. Patrick et al., PRODUCTION OF AN INDOLIZIDINE ALKALOID, SWAINSONINE BY THE FILAMENTOUS FUNGUS, METARHIZIUM-ANISOPLIAE, Biotechnology letters, 15(10), 1993, pp. 997-1000
The physiology of Metarhizium anisopliae has been studied with a view
to improving swainsonine production. In preliminary work, the stabilit
y of pure swainsonine in aqueous solution has been investigated under
varying conditions of pH and temperature and in the presence of oxidiz
ing agents. The effects of oxygen on the growth and morphology of M.an
isopliae and the production of swainsonine were also examined. Shaken
flask fermentations have been carried out in order to develop a medium
suitable for production of swainsonine
