“…Alternaria has been previously detected by the viable (Arnold et al, 1987;Rojas et al, 2002) and nonviable methods (Herrera et al, 2003), but this is the first time, they are identified at species level in Caribbean outdoor areas. Alternaria tenuissima has been reported in other parts of the world (AbuDieyeh et al, 2010) and N. sphaerica has been mainly found in Cuban aerobiological indoor environments (Borrego & Perdomo, 2012).…”

“…Syncephalastrum racemosum, Rhizopus stolonifer and R. oryzae have been previously reported in indoor environments of Cuba only, mainly in warehouses and stores (Borrego & Perdomo, 2012). Trichoderma was previously isolated from indoor and outdoor environments (Borrego et al, 2010).…”

“…However, outdoor studies are scarce, and most of them were focused on the assessment of the fungal destructive effect on cultural heritage (Borrego et al, 2010;Borrego & Perdomo, 2012; or about the air quality evaluation in homes (Aira et al, 2002). The use of volumetric systems for fungal propagules sampling represents a great advantage in relation to gravimetric methods since they allow to obtain quantitative results as colony forming units per volume of air (CFU/m 3 ).…”

“…Estos plantean que dichos gé-neros son los géneros más representativos en el aire tanto de interiores como de exteriores, por lo que se consideran contaminantes por excelencia del patrimonio cultural. Otros autores [31][32][33][34][35][36][37] han demostrado que los conidios de Aspergillus y Penicillium en general son más numerosos en el aire de interiores que de exteriores de lo que se deduce que muchos de ellos provienen de los materiales y soportes contaminados en dicho medio. Penicillium es el género más abundante en ambientes interiores de viviendas y Aspergillus es el más común en el aire de viviendas húmedas al igual que en archivos, museos y almacenes soterrados seguido de Penicillium [33].…”

ResumenEl biodeterioro del Patrimonio Cultural es uno de los procesos de daño más importantes en los climas tropicales, caracterizados por elevadas humedades y temperaturas. Estas favorecen la colonización biológica y el crecimiento y desarrollo de diferentes organismos vivos sobre el sustrato material de los bienes patrimoniales. Entre estos organismos destacan los hongos e insectos por su ubicuidad, fisiología y medios de dispersión. En el presente trabajo se exponen resultados de muestreos microbiológicos directos y ambientales realizados en diferentes museos de La Habana, Cuba. Se detectaron concentraciones fúngicas del aire correlacionadas con la humedad relativa del ambiente. Los géneros fúngicos predominantes en muestreos directos y aéreos fueron Aspergillus, Penicillium y Clasdosporium, especies con potencialidades fisiológicas que determinan el elevado riesgo de biodeterioro fúngico de las colecciones albergadas en las instituciones estudiadas. Estos estudios permitieron el establecimiento de políticas preventivas eficientes que aumentan la esperanza de vida de este Patrimonio Cultural de Cuba.

Os géneros de fungos predominantes no ar interior e nos diferentes substratos testados foram Aspergillus, Penicillium e Cladosporium, que têm potencialidades fisiológicas que representam um elevado risco de micobiodeterioração das colecções albergadas pelas instituições estudadas. Os estudos levados a cabo permitiram estabelecer políticas de prevenção eficientes que aumentam a esperança de vida deste Património Cultural de Cuba.Microbiologia aplicada: uma ferramenta para a conservação do Património Cultural

“…Such risks appears to be lower in naturally ventilated buildings in comparison to those ventilated through mechanical means. For instance, in an earlier study conducted by Borrego and Perdomo [5], fungal contamination was reported to be reduced in buoyancy driven ventilated building than the forced ventilated counterparts. The reason, according to the study, is not unconnected with the natural ventilation that facilitate movement of particles in the air thereby making spores deposition difficult.…”

Air Handling Units in mechanical ventilation system possess a high degree of potential to circulate contaminants within occupied spaces of a building which often results in sick building syndrome (SBS), building related illness (BRI) and other indoor air quality (IAQ) related issues. This happens despite the expected role of ventilation systems to create a balance of thermal comfort and indoor air quality to the building occupants as well as the stored components. In the hot and humid climate mechanical ventilation systems play an important role of controlling the indoor hygrothermal conditions. Inadequate performance of the mechanical ventilation systems result in several issues ranging from human occupants discomfort, mechanical damages to archival materials and mould problem amongst others. This study presents the measurement and analysis of the mechanical ventilation systems' performance and its effect on various indoor spaces in an academic building in Malaysia. Measurement of airflow, thermal and hygric conditions of the facility together with the aero-biological sampling were executed. The ventilation performance assessment revealed that the AHU fails in its cooling and dehumidification capacities as most of the occupied zones witnessed elevated humidity and low temperature and hence poor hygrothermal performance. On the other hand, results of bio-aerosol assessment indicates that the AHU performs well in its decontamination capacities by reducing the microbial level between the AHU and the occupied zones. The dominant species of mould in the assessed spaces are Penicillium sp., Yeast, Cladosporium sp., and Chaetomium sp. with 100 % occurrence in all the assessed space. On the other hand, Black Mold, Syntalidium sp., and zygomycetes are the least species in spaces with 25 % occurrence. The presence of black mould portends a great danger to the occupants' health and therefore requires urgent attention.
