biosynthesis of four new diterpenoids was observed following the addition of a marine alpha-proteobacterium to an established culture of the marine-derivedfungus Libertella sp. The fungal strain and the marine bacterium, cultured alone, do not produce diterpenoid metabolites. The induced diterpenoids, libertellenones A-D, are cross-conjugated ketones of the pimarane class. The libertellenones show varying
