Fungi on mummified human remains and in the indoor air in the Kuffner family crypt in Sládkovičovo (Slovakia)

• The fungal microflora isolated from mummified remains was investigated.
• Fungal airborne community was also isolated from mausoleum environment.
• Fungal identification by ITS sequencing and biodegradative properties was assessed.
• Isolates belonged mainly to the orders Eurotiales, Mucorales and Microascales.
• Airborne fungi showed stronger deterioration activity respect the human counterpart.

Microscopic fungi were isolated from different materials including muscles, bones, skin and funeral clothes from the mummified human remains of three members of the Kuffner's family and from the surrounding air environments. Their hydrolytic abilities such as cellulolytic, lipolytic, and proteolytic-keratinolytic were also assessed. The most isolated fungi, from human remains, belonged mainly to the species of Aspergillus (Aspergillus candidus, Aspergillus calidoustus, Aspergillus fumigatus, Aspergillus niger, Aspergillus sydowii, Aspergillus terreus, Aspergillus ustus, Aspergillus venenatus, Aspergillus versicolor, Aspergillus westerdijkiae) and Penicillium (Penicillium chrysogenum, Penicillium commune, Penicillium crustosum, Penicillium griseofulvum, Penicillium hordei, Penicillium polonicum). Aspergilli and penicillia were the predominant actors also in the air samples, but also many strains belonging to the Rhizopus group were isolated as well. Several fungi exhibited different hydrolytic ability, the most active isolated from human remains belonged to the species A. candidus, A. westerdijkiae, Coprinellus xanthothrix, P. chrysogenum, P. commune, P. griseofulvum and Scopulariopsis brevicaulis. The species recovered from the air displayed stronger deterioration characteristics as compared to human samples. This study can be considered one of few investigations focused on mummified human remains conserved in this kind of the environment.
