Abstract

|
Scopolamine and hyoscyamine are important anticholinergic compounds. To increase the productivity, we have selected various elicitors and developed culture system using a bubble column bioreactor (BCB). As the same manner of elicitation in flask cultures, the elicitors were introduced into BCB cultures and the productivity was investigated. Except the bacterial elicitor of Staphyllococcus aureus, the elicitors inhibited hyoscyamine production. In scopolamine production, the elicitors revealed different responses from the results obtained in flask cultures. The elicitors of KCl and Candida albicans less increased the production than flask cultures. However, methyl jasmonate and S. aureus showed stronger positive effects on tropane alkaloid production. In particular, S. aureus was the most effective elicitor on scopolamine production and the elicitor resulted in the highly increased production, approximately 10 times higher than the control culture.
