LOPEZ-ARANDA, Bélgica G.. MICROBIOLOGICAL CHARACTERIZATION OF WAREHOUSES OF THE MUSEUM TUMBAS REALES DE SIPÁN IN LAMBAYEQUE, PERU. Zaranda ideas [online]. 2020, vol.18, n.2, pp.136-145. ISSN 1853-1296.

The objective of the study was to evaluate the biodeterioration of the archaeological collections of the Tumbas Reales de Sipán museum warehouses in Lambayeque. The surface of 24 textiles and 30 bones with physical alterations in four warehouses was sown and planted on agar, at 30 ° C in aerobiosis for up to 10 days. 100 % of textiles presented alterations in texture, coloration, and integrity and 45.8 % at the edges. Bacteria were quantified with an average of 4.9 x 104 CFUm-2 in textiles and 1.4x105 CFUm-2 in bones. Fungi were quantified with an average of 7.1x103 CFUm-2 in textiles and 5.2x103 CFUm-2 in bones. The genera Bacillus, Micrococcus, Staphylococcus, Streptococcus and Streptomyces were identified in textiles and bones. In textiles, the genera Aspergillus, Alternaria, Cladosporium, Chrysosporium, Geotrichum, Gliocladium, Penicillium, Rhizopus, and Scopulariopsis were identified. In skeletons Aspergillus, Alternaria, Curvularia, Cercospora, Cladosporium, and others.
