GARCIA MINIET, Michel  and  SANCHEZ ESPINOSA, Renier. Study of airborne fungal concentration at the Archivo Municipal de Cardenas, Cuba. Rev. Soc. Ven. Microbiol. [online]. 2012, vol.32, n.1, pp.37-43. ISSN 1315-2556.

The control of certain parameters in indoor environments, such as temperature and relative humidity, constitutes an essential element for the conservation of heritage, and preservation of human health, due to the potential risk implied by the presence of microorganisms in these environments, specifically fungi. The purpose of this study was to determine the airborne fungal concentration at the Archivo Municipal de Cardenas (Cuba), establish the taxonomic identification of isolates and describe the biodeteriorating and pathogenic potential represented for the documentary heritage and human health, respectively. We used a SAS Super 100 biocollector and Petri dishes containing an adequate culture medium for microbiological sampling, and later determined the biodeteriorating capacity of the strains. The fungal concentration values obtained at site 1 were considerably higher than those obtained at site 2, allowing classifying the first one as highly contaminated. The predominant fungal genus was Penicillium, registering 53% and 81.8% at sites 1 and 2, respectively. All the isolates presented marked cellulolytic activity and acid production, while 58% excreted pigments to the medium, verifying their biodeteriorating capacity. The fungus genus isolated represents potential pathogens for human health
