N-demethylation of nicotine and reduction of nicotine-1'-N-oxide by Microsporum gypseum.

AUTOR(ES)
RESUMO

Several microorganisms were examined for their abilities to convert S-nicotine into nornicotine. Five microorganisms including Microsporum gypseum (ATCC 11395) produced nornicotine and three unknown metabolites. M. gypseum efficiently reduced nicotine-1'-N-oxide to nicotine, but no nornicotine was obtained when the N-oxide was used as substrate.
