Abstract: Growth parameters of fungi that previously considered as active growing in conditions of ChNPP 4th block were studied. Such growth parameters were radial growth velocity, hyphal growth unit (HGU) and also intensity of colonization of substratum. All experiments were made on 2 types of nutrient medium: optimal medium malt agar and starving agar. Two types of radioactive substrates colonization by fungi were identified. The growth of main species-biodestructor Cladosporium sphaerospermum on other concentrations of glucose was investigated and its ability to fixation of carbonic acid form air and oligotrophia were shown. The trophic relations of main species-biodestructor Cladosporium sphaerospermum and two species that constantly were isolated with it were also studied. It was shown that fungi that previously considered as active growing in conditions of ChNPP 4th block are really those.
