[Peculiarities of growth and development of strains Hormoconis resinae (Lindau) V. arx & De Vries F. Resinae and Cladosporium sphaerospermum penz].

ABSTRACT

The work deals with the effect of limitation of organic carbon (glucose) on the growth and morphology of two species of microscopic fungi Hormoconis resinae and Cladosporium sphaerospermum (11 strains), isolated from premises of the 4th unit of the Chernobyl NPP and isolation places which arc pure from radionuclides. The dissimilar reaction of each of the species to decreasing the amount of organic carbon in the culture medium has been established. Ontogenesis reduction was observed for both species under the conditions of limitations of organic carbon. In was manifested for H. resinae in reduction of the typical conidial sporulation and in transition to micelial way of existence, and only conidial sporulation and formation of "empty" micelium Were registered under such conditions for C. sphaerospermum. The studied strains were related to 3 ecologic groups by oligocarbotolerance criterion typical saprotrophs, intermediate group, strains with a tendency to oligocarbotolerance.
