Abstract:
The monokaryotic yeast phase of the heterobasidiomycete Itersonilia perplexans, unlike the hyphal phase, was found to be sensitive to mycocins produced by killer strains of Cryptococcus humicola, Cr. laurentii, Cystofilobasidium bisporidii and Rhodotorula fujisanense. Both the yeast and hyphal phases wer resistant to mycocins of Cr. podzolicus, Filobasidium capsuligenum, Rhodotorula glutinis, Rh. mucilaginosa, Rh. pallida, Sporidiobolus johnsonii, Sb. pararoseus and Sporobolomyces alborubescens. The different sensitivity patterns of yeast and hyphal phases are probably caused by biochemical differences in the cell walls.
