Monoterpenes with an unsaturated hydrocarbon structure are mineralized anaerobically by the denitrifying beta-proteobacterium Alcaligenes defragrans. Organic acids occurring in cells of A. defragrans and culture medium were characterized to identify potential products of the monoterpene activation reaction.
