[Survivability of some black yeast-like fungal species under UV-irradiation].

The survival of 4 species (14 strains) of black-pigmented yeast-like fungi, isolated from radioactive polluted ecotopes, after UV-irradiation has been studied. Their survival was different in the limits of 3 orders from 0.7 to 0.

[Screening of alpha-N-acetylgalactosaminidase producers among microorganisms of different taxonomic groups].

Screening of producers of alpha-N-acetylgalactosaminidase among 854 strains of micromycetes, 171 yeast and 357 bacterial cultures has been carried out. A capacity to synthesize the enzyme was revealed in 11% of cultures. Representatives of Aspergillus genus (activity--0.
