| Abstract: | Examination of different species of local fungi, grown on two nutritive solutions of different composition, for alkaloid formation was investigated. The formation of alkaloids was confined to four species, namely: Geotrichum candidum, Mucor hiemalis, Aspergillus flavus and Rhizopus nigricans. A comparative study of the growth as well as the formation of alkaloids by these species and by Claviceps purpurea NRRL was carried out. Methods were also described with which the different alkaloids produced by the experimental strains were identified. Peptides as well as clavine type alkaloids were detected in all cases except with Mucor hiemalis where a compound corresponding to ergosine was the only alkaloid present. |
