[Morphological and biosynthetic activity of Trichothecium roseum in relation to the polynuclear conidia of the fungus].
The effect of the number of the nuclei on the morphological and synthetic variability was studied with the conidia of Trichothecium roseum. Treatment of suspensions of the conidia with 0.5--1.0 percent solutions of colchicine during two hours increased the number of the nuclei in the conidia, induced the formation of giant colonies, and augmented the ability to produce antibiotics. No reliable differences have been found in the levels of proteolytic activity between the control strains and the strains treated with colchicine.
