Assessment of biological colonization of historic buildings in the former Auschwitz II-Birkenau concentration camp

A study assessing biological colonization of historic buildings at Auschwitz II-Birkenau revealed significant biodiversity among colonizing organisms, including bacteria, fungi, cyanobacteria, algae, lichens, and bryophytes. While microbial activity on barrack surfaces was not elevated, symptoms of biodegradation were observed, particularly in wooden structures. The research identified over 30 species of lichens and mosses, with notable differences between wooden and brick buildings. Cyanobacteria and algae predominantly affected floors and bathroom walls, while lichens and bryophytes colonized outer surfaces more extensively on brick structures. This assessment provides critical data for developing targeted disinfection and conservation strategies to mitigate progressive biodegradation.
