Triterpenoid production by I. obliquus under submerged fermentation.
Trametenolic acid, 3β-hydroxy-lanosta-8,24-dien-21-al, inotodiol, and betulin.
Addition of MeJA with Tween-80 or fatty acids stimulates the production.
Fatty acids are less effective than MeJA on the production.
Different effect on biosynthesis of individual tritepenoid components.
