“…The study of microbial volatile organic compounds (MVOCs) produced by moulds developed in indoor environments has been addressed by several authors, especially in relation with dampness situations and possible human health problems (Cabral, 2010;Moularat et al, 2008;Polizzi et al, 2009;Wady et al, 2003). Since the 1990s, MVOCs are often discussed to be associated with the sick building syndrome (SBS) because of their suspected role as responsible for a wide range of specific and non-specific symptoms and discomfort (Elke et al, 1999;Larsen et al, 1998;Matysik et al, 2008;Meyer et al, 1998;Wessén and Schoeps, 1996).…”

“…1-octen-3-ol and 3-octanol, as well as ketones and furans were addressed as indicators of mould, recognised both on pure culture studied, on agar substrate, and on wallpaper and building materials (Polizzi et al, 2012). Aspergillus and Penicillium are the most investigated fungal genera in MVOC studies (Fiedler et al, 2001;Matysik et al, 2008Matysik et al, , 2009Moularat et al, 2008;Polizzi et al, 2012;Schuchardt and Kruse, 2009;Wady et al, 2003, Wady andLarsson, 2005) because of their ubiquity in indoor environments (Cabral, 2010;Samson et al, 2004), also in association with the biodeterioration of Cultural Heritage (Micheluz et al, 2015;Sterflinger, 2010;Zyska, 1997). However, in the recent years, specific fungal contamination emerged inside Italian archives and library, mainly caused by a xerophilic fungus with a lack of knowledge about its MVOC emission capability, i.e.…”

The principal fungal species isolated from a contaminated library environment were tested for their microbial volatile organic compound (MVOC) production ability. Aspergillus creber, A. penicillioides, Cladosporium cladosporioides, Eurotium chevalieri, E. halophilicum, Penicillium brevicompactum and P. chrysogenum were cultivated on suitable culture media inside sample bottles specifically designed and created for direct MVOC injection to a GC-MS instrument. The fungal emissions were monitored over several weeks to detect changes with the aging of the colonies, monitored also by respirometric tests. A total of 55 different MVOCs were detected and isopropyl alcohol, 3-methyl-1-butanol and 2-butanone were the principal compounds in common between the selected fungal species. Moreover, 2,4-dimethylheptane, 1,4-pentadiene, styrene, ethanol, 2-methyl-1-butanol, acetone, furan and 2-methylfuran were the most detected compounds. For the first time, the MVOC production for particular fungal species was detected. The species A. creber, which belongs to the recently revised group Aspergillus section Versicolores, was characterized by the production of ethanol, furan and 1,4-pentadiene. For the xerophilic fungus E. halophilicum, specific production of acetone, 2-butanone and 1,4-pentadiene was detected, supported also by respirometric data. The results demonstrated the potential use of this method for the detection of fungal contamination phenomena inside Cultural Heritage's preservation environments.

“…Some of the airborne fungal species (Aspergillus spp., Penicillium spp., Cladosporium spp.) that occur in the mine excavations and galleries can possibly cause individual allergies and fungal infections in some exposed workers (Gamboa et al 1996;Obtułowicz 2006;Cabral 2010).…”

We determined the species composition and the concentration of colony forming units of airborne bacteria and fungi in a coal mine in Poland. We sampled at six locations in a working shaft at about 500-600 m below ground level. Air samples were collected between 6 and 9 a.m. using the impact method onto Potato Dextrose Agar and TSA. The volume of air filtered for each coalmine sample was 50 L. We found 11 fungal species, with Penicillium meleagrinum and P. notatum as the most common. Six bacterial genera were identified, with Micrococcus spp. as the most common. There were no pathogenic fungi or bacteria identified. The concentration of fungal spores and bacteria in the coal mine air is not a direct hazard to mine workers.

“…may represent a direct health threat for animal husbandry workers. For the sheer fact that they are capable of producing mycotoxins [30] or able to cause mycoses and other respiratory system diseases [31], these fungi are considered one of the important components of indoor bioaerosol. Nevertheless, in order to confirm such a causative relationship in any individual case it is necessary to conduct a series of molecular tests, as not all of the isolates derived from air sampling show the ability to synthesize mycotoxins [32,33].…”
