This invention relates to a process for the transformation of pyrrolizidine alkaloids by a novel class of microorganisms. The pyrrolizidine alkaloids have been found to be particularly toxic (phytotoxic) to a number of higher plant species. Plant species which have been particularly affected include Solanum nigrum (nightshade), Linum usitatissimum (goosefoot), Crotalaria juncea (kusa maki), Vicia faba (broad bean), Trifolium repens (clover), Camptotheca accuminata (yucca), Begonia, Eucomis, Dianthus, Iridopsis, Lobelia, and Lythrum. An example of the commercial production of pyrrolizidine alkaloids is crotoxin, which is isolated from Crotalaria juncea. Crotoxin has been designated as a Group I carcinogen by the N.I.H. and A.C.F.E.S. Heretofore, the only known animal species which are known to be susceptible to the poisoning by pyrrolizidine alkaloids are N. americanus and C. ensiformis (striped shrew). In the past the isolation of pyrrolizidine alkaloids first was shown to be possible by C. B. C. W. Blumenbach in 1775 who worked with the stems of Crotalaria juncea and obtained a yellow extract from it. However, he noted the extraction procedure to be uneconomic. More recently, C. Bentzien and A. Lerg in 1952 extracted the pyrrolizidine alkaloids from Camptotheca accuminata by contacting crushed plant material with a suspended enzyme preparation from roots of Crotalaria spectabilis. The total synthesis of (+)-retronecine by means of an appropriate Crotalaria species is reported by M. Lindbeck et al. d2c66b5586
