Analyzing indoor mycobiomes through a large‐scale citizen science study in Norway

摘要: In the built environment, fungi can cause important deterioration of building materials and adverse health effects on occupants. Increased knowledge about indoor mycobiomes from different regions world, their main environmental determinants, will enable improved air quality management identification risks. This is first citizen science study at a large geographical scale in Europe, including 271 houses Norway 807 dust samples three house compartments: outside building, living room bathroom. The fungal community composition determined by DNA metabarcoding was clearly between outdoor samples, but there were no significant differences two compartments. 32 selected variables, related to features occupant characteristics, accounted for 15% overall variation composition, with compartment as key factor (7.6%). Next, climate driver (4.2%), while variables had minor influences (1.4% 1.1%, respectively). house-dust dominated ascomycetes (⁓70%) Capnodiales Eurotiales most abundant orders. Compared showed higher species richness, which probably due mixture sources. indicator belonged ecological groups allergenic potential: xerophilic molds skin-associated yeasts. Our results suggest that successful approach unraveling microbiome scales.
