| Zusammenfassung: | The wall paintings in the inner area of the church of the St. George monastery in Voroneţ, Rumania, show a big area with pink bacterial infestation. The extensive use of bee wax-made candles and votive smoke from the daily (orthodox) liturgy has resulted into continuous stress due to the smoke gases/burning-products deposited on the walls and arch surfaces. Investigations focused on the bee wax, votive smokes, and soot with reference to the importance (for the bacteria), of room climate, calcium nitrate, calcium sulphate, and of harmful effect of the bacteria. The choice of the reference area represents the grounds for a long term monitoring of the bacterial infestation. The results of biocide treatments in the laboratory and on the test areas in the monastery led to the development of a restoration proposal regarding bacteria. |

Zusammenfassung in rumänischer Sprache: Rezumat: Pictura bisericii Sf. Gheorghe din Voronet (România) prezinţa un atac biologic cu bacteria roz pe o suprafata mare. Folosirea (indelungata) a lumanarilor din ceara de albinesi a candelelor la slujbele religioase (ortodoxe) zilnice au condus la depuneri consistente de fum pe pereti si pe suprafata arcelor. Investigatiile s-au facut in special pentru ceara de albine, fumul de la candele si funingine cu referiri la importanta (pentru bacterie) a climatului, sarurilor (azotat de calciu si sulfat de calciu) si a efectul daunator al bacteriei. Alegerea zonelor in discutie reprezinta suprafete pe care s-a realizat o monitorizare indelungata a atacului biologic cu bacterie roz. Rezultatele experimentale ale biocidarii in laborator si pe zona de lucru prin expunere cu culturi bacteriene sunt descrise in conceptul de restaurare. Cuvânt-titlu : bacteria roz, vum votiv, ceara de albine, azotat de calciu si sulfat de calciu, biocizi, concept de restaurare |
