| Popis: | There is a significant deterioration of mycological condition of premises with modern interiors synthetic materials, including plasterboard which have significant demand. The aim was to determine the species, which are specific to plasterboard and damage it under operating conditions. Microscopic fungi were isolated from samples of plasterboard and air in homes that had signs of excessive moisture and office premises with no signs of moisture. Methods of cumulative culture and serial dilutions on agar nutrient media were used to isolate fungi in pure culture. Frequency of occurrence of fungal species for mycobiota of individual premises was calculated. Thus, mycobiota of plasterboard constructions was investigated in different premises; it was represented by 25 species of microscopic fungi belonging to 12 genera of Ascomycota division. It was established that the number of species of microscopic fungi, that are contaminants of plasterboard in conditions of excessive moisture areas, far exceeds the average rate for premises with no signs of moisture. It was shown that in climates of Kyiv main contaminants of plasterboard constructions are species Stachybotrys chartarum, Aspergillus niger, A. sydowii, A. versicolor, A. ustus and Sarocladium strictum, which are hazardous to health and life of humans and warm-blooded animals. |
