A novel process for the fermentation of phytosterol compositions to androstenedione (androst-4-ene-3, 17-dione, AD) and/or androstadienedione(androsta-1, 4-diene-3, 17-dione, ADD) is disclosed. The process utilizes the micro-organism Mycobacterium MB 3683, and selected suitable solubilizing age...
One possible route leads 4-cholesten-3-one to AD, which is then oxidized by 3-ketosteroid Δ1 dehydrogenase (KSTD) or 3-ketosteroid 9α-hydroxylase (KSH) to become ADD or 9α-hydroxy-4-androstene-3,17-dione (9OHAD), respectively. ADD and 9OHAD is then transformed into 9α-hydroxy-1...
