title: Microbial degradation of steroid alkaloids. Effect of nitrogen atom in the side-chain on the microbial degradation of steroid alkaloids.
abstract: The microbial dehydrogenation of steroid alkaloids follows the dehydrogenation pattern of steroids until the 3-keto-1,4-diene stage. No side-chain cleavage or degradation of the steroid nucleus is observed. Side-chain cleavage of tomatidine is achieved only by previous induction of side-chain splitting enzymes.
