Comparison of indoor air microbiota of Prykarpattya museums

Monitoring of air microbiota state of various museum apartments, that is the basic source of spreading of microorganisms able to destroy exhibits or buildings, is the actual problem of nowadays. Indoor air microbiota (quantitative and qualitative composition) of the Lviv historical museum, Ivano-Frankivsk regional art museum and Lviv religion history museum was analysed. It was established that air of most apartments of investigated museums insignificantly populated by microorganisms (their amount did not exceed possible norms). However, the fact of isolation of great quantities of mould fungi troubled, in particular, known damagers of various materials of museum exhibits. It is confirmed, that the common amount of microorganisms grows with the increasing of temperature and humidity of air, and with the increasing of number of visitors − only amount of bacteria. It was established that in indoor air of all museums happen mostly the identical genera of mould fungi, in particular, in air of Lviv historical museum − Penicillium and Aspergillus − (35 and 25 %, accordingly); Ivano-Frankivsk regional art museum – Penicillium, Aspergillus and Alternaria (36, 25 and 6 %, accordingly); Lviv religion history museum – Aspergillus, Penicillium, Cladosporium, Alternaria, Mortierella (26, 21, 15, 11 and 10 %, accordingly). Accordingly to the obtained results correspon­ding recommendations were given to administrations in relation to the improvement of museum exhibits storage conditions and inhibition of microbiota development
