Influence of nystatine, a polyene antibiotic, on the formation of complex-bound sterols and the formation of conidia by Coprinus cinereus (author's transl)

In contrary to the wild strain, a monocaryotic mutant of Coprinus cinereus (basidiomycete) does not contain hydrosoluble, complex-bound sterols. Under nystatine-treatment, however, the mutant is induced to produce this kind of stereols in abundance. Furthermore, nystatine highly increases sporulation of the mutant and decreases sporulation of the wild strain.
