ABSTRACT

RESUMEN Las bacterias y los hongos son un riesgo potencial para el material arqueológico y trabajadores de los museos en Lambayeque, Perú. Con el objetivo de cuantificar la microbiología ambiental aislada del museo Tumbas Reales de Sipán, se muestrearon cuatro almacenes, con Agar Nutritivo y Agar Papa Dextrosa, incubándose a 30 °C, en aerobiosis, hasta por 7 días, para bacterias y, hasta por 10 días, para hongos. Se cuantificaron bacterias con un máximo de 2,7x104 UFC cm-2, en las superficies de pisos y paredes; 1,4x103 UFC m-3, en el aire y hongos filamentosos, con un máximo de 7,5x104 UFC cm-2, en las superficies y 9,1x104 UFC m-3, en el aire. Se aislaron e identificaron los géneros de bacterias: Bacillus, Micrococcus, Acinetobacter, Nocardia, Streptococcus, Staphylococcus y Streptomyces y los géneros de hongos filamentosos: Aspergillus, Cladosporium, Circinella, Syncephalastrum, Penicillium, Alternaria, Staphylotrichum, Cercospora, Rhizopus, Cunninghamella, Chrysosporium, Nigrospora, Stachybotrys, Gliocladium y Verticillium.


ABSTRACT Bacteria and fungi are a potential risk to archaeological material and museum workers in Lambayeque, Peru. In order to quantify the isolated environmental microbiology of the Tumbas Reales de Sipán museum, four warehouses were sampled with Nutritive Agar and Papa Dextrose Agar, incubated at 30 °C in aerobiosis for up to 7 days for bacteria and up to 10 days for fungi. Bacteria were quantified with a maximum of 2.7x104 CFU cm-2 on the floor and wall surfaces, 1.4x103 CFU m-3 in the air and filamentous fungi with a maximum of 7.5x104 CFU cm-2 on the surfaces and 9.1x104 CFU m-3 in the air. Bacterial genera were isolated and identified: Bacillus, Micrococcus, Acinetobacter, Nocardia, Streptococcus, Staphylococcus and Streptomyces and the filamentous fungal genera: Aspergillus, Cladosporium, Circinella, Syncephalastrum, Penicillium, Cyrryspunrichum, Cyrrysopositive, Cyrrysylopola Rushingum, Cyrrysophyllizum, Nigrospora, Stachybotrys, Gliocladium and Verticillium.
