Abstract Our country, the Plurinational State of Bolivia and the city of Sucre have been characterized over time by its culture and tourism. In 1991 this city known as the White City of America, among the cultural heritage, was declare by UNESCO in Bolivia as the "Historical City of Sucre" for hosting cultural wealth such as the works of art found in different museums in the city. Among those, the Museo Universitario Colonial Charcas is stood out as the most prestigious nationwide. It has a wide collection of paintings concerning to the colonial, Republican and contemporary times. The colonial art room has 1300 works on different materials (wood, marble, glass) and 870 oil paintings on canvas, in which it was worked since last years with the Biochemistry Department of the University to determine first, the microbial communities that deteriorate these works as well as the microbiological control of environments. Based on the information obtained, this work had its continuity with the purpose of providing an alternative solution to the diagnosis made, showing the microbial sensitivity to SOCUZINC (CuSO4 1.6%/Zno 8%) when applied alongside latex paints on walls for preservation of oil paintings. A quantitative, descriptive and cross-sectional study was applied in the methodological part. Regarding the results, the effectiveness of the 1.6% CuSO4and 8% ZnO chemicals as microbial inhibitors applicable to the Museum's environments together with latex paint was confirmed by qualitative and quantitative microbiological techniques and thus contribute to the remaining works of the Colonial Charcas Museum

Keywords : Deteriorati on of paintings; microbial communities in Museums; sensitivity to chemicals and preservation.
