Calidad microbiológica del ambiente de la Biblioteca Alfonso Patiño Rosselli, Tunja- Boyacá (Colombia)

Abstract

Air quality of indoor environments can be influenced by the presence of biotic and abiotic agents such as microorganism, spores, acari, and pollen, natural components in these environments, which can be transported from the outdoor air by dust particles.. The microorganisms present in the environment of the Library Alfonso Patiño Rosselli, Tunja (Boyacá) were evaluated and it was determinated which of the isolated fungal genera could represent risk of biodeterioration on the documents. The open Petri dish sedimentation method was employed for the microbiological sampling, using Sabouraud Agar for fungi isolation and Nutrient Agar for bacteria, whereas for sampling of documents, the Potato Dextrose Agar as culture media was utilized. In the environment, the highest diversity was represented by fungi with 23 isolated genera, predominating Cladosporium spp., whereas yeasts were less representative, with Geotrichum the predominant genus. Regarding bacterial forms, Gram positives were the most abundant, being Staphylococcus the most prevalent genus of the 13 identified ones, with respect to three genera of Gram negative. On books, Aspergillus spp., and Penicillium spp. were the predominant fungi. Microbial concentration of environment was high, but within the limit of sanity of public places to be considered as not contaminated; however, it is important to establish control measures of these microbial populations and the environmental conditions that could favor its development.

Fungal diversity in environments of repository of the national archive of the Republic of Cuba from the 80s to 2022

“…The genera Acremonium, Aureobasidium, Chaetomium, Chrysonilia, Exophiala, Trichophyton and Torula have been detected in the air of foreign archives, libraries and museums. 32,37,64,67,70,72,73,77,77,85,[86][87][88]90 Likewise, the genera Itersonilia and Sprorobolomyces were isolated from dust settled on books in an Italian library 93 and a member of Botryotrichum genus was isolated from the documents surface preserved in a Polish library. 94 On the other hand, the genera Aureobasidium, Bipolaris, Sepedonium, Torula and Trichophyton were found in repositories of the Provincial Historical Archive of Pinar del Río (located in the westernmost province of the Cuba), 60 while the genera Torula and Zygosporium were found in the air of repositories of the Provincial Historical Archive of Santiago de Cuba (one of the eastern provinces of the country).…”

Bacterias y hongos en el ambiente y sobre la superficie de documentos de un archivo forense colombiano

“…Similarmente, Alternaria s.p. se ha encontrado en ambientes de archivos y bibliotecas del mundo (Borrego Alonso y Perdomo Amistad, 2014;Borrego et al, 2008;Carlo et al, 2016;García Miniet y Sánchez Espinosa, 2012;Giraldo-Castrillón et al, 2009;Molina Veloso y Borrego Alonso, 2014;Pantoja et al, 2012;Toloza y Lizarazo, 2013;Zhu et al, 2003) y se ha asociado como el agente causal de alergias e infecciones respiratorias (Carlo et al, 2016).…”

Micromicetos anemófilos de patogenicidad condicionada y biodeterioradores, en ambientes interiores del Centro Cultural de San Marcos

“…[8]. Se han efectuado numerosos estudios con la finalidad de demostrar la presencia de micromicetos en ambientes interiores; los que se han aislado con mayor frecuencia son los filamentosos Cladosporium, Penicillium, Aspergillus, Fusarium, Alternaria y Acremonium; y las levaduras Rhodotorula y Candida [13,14,15].…”
