Answer: medicine

Question: Question: With regard to the alkaloids derived from ergoline:
Options: <0> They can be obtained by fermentation of pure Claviceps purpurea cultures and derived from phenylalanine and isoprene obtained by the mevalonic acid route (MVA). <1> They can be obtained by fermentation of pure cultures of Claviceps purpurea and derived from tyrosine and isoprene obtained by the DOXP route. <2> They can be obtained by fermentation of pure cultures of Claviceps purpurea and derived from tryptophan and isoprene obtained by the route of mevalonic acid (MVA). <3> They can be obtained by rye infection with Claviceps purpurea spores and derived from tryptophan and isoprene obtained by the DOXP route. <4> They can be obtained by wheat infection with Claviceps purpurea spores and derived from tyrosine and isoprene obtained by the mevalonic acid (MVA) route.
