Microbial Hydroxylation of Indole Alkaloids [PDF]

Applied Microbiology, 1964
The hydroxylation of the indole-type alkaloids, yohimbine, α-yohimbine, β-yohimbine, and corynanthine, was achieved with several genera of higher fungi and species of Streptomyces . Microorganisms were found which monohydroxylated these compounds in three different positions.
