“…alone caused damage worth hundreds of millions of pounds (Carlile et al 2001). Approximately, 120 species have been found in North German buildings (Huckfeldt and Schmidt 2006;Schmidt and Huckfeldt 2011), and this number corresponds to surveys in other countries (Ważny and Czajnik 1963;Guillitte 1992;Alfredsen et al 2005). In the Northern Hemisphere, the interior structural timbers are mainly coniferous woods, and the most important wood-degrading fungi in Europe and North America are brown-rot fungi.…”

Wood decay by indoor basidiomycetes at different moisture and temperature

Some of the most important indoor wood-decay basidiomycetes were investigated in Erlenmeyer flask experiments, in which 50 Pinus sylvestris sapwood samples with moisture content (MC) of 16% were piled, in view of the parallel influence of wood moisture and temperature on decay in buildings. In the piles, the moisture flow from the liquid at the bottom was interrupted by a metal ring at layer 7. Laboratory incubations with Antrodia xantha, Coniophora puteana, Donkioporia expansa, and Gloeophyllum abietinum over the temperature range of 10°C-25°C showed that fungi are able to colonize, moisten, and thereafter degrade wood samples below fiber saturation, if a moisture source nearby is available. In extreme cases, mycelium grew on wood with 17.4% final MC, and wood mass loss of more than 2% occurred at 24.6% moisture.

“…Similarly, P. spadiceum colonises typically dead hardwood, and demonstrated potential for the biological treatment of landfill leachates and textile wastewaters [ 51 , 52 , 53 ]. Moreover, a large-scale study targeting indoor wood-decaying fungi in 2000 buildings over a 9-year period, identified B. adusta in beams and windows of houses [ 54 ]. However, most of the fungal species identified in the current study are also known to be associated with respiratory, eye and skin symptoms in indoor environments [ 55 , 56 , 57 , 58 ].…”

Research into the biodeteriorative potential of fungi can serve as an indicator of the condition of heritage items. Biodeterioration of canvas paintings as a result of fungal metabolic activity is understudied with respect to both the species diversity and mechanisms involved. This study brings new evidence for the physiology of fungi biodeteriorative capacity of canvas paintings. Twenty-one fungal isolates were recovered from four oil paintings (The Art Museum, Cluj-Napoca) and one gouache painting (private collection), dating from the 18th to 20th centuries. The species, identified based on the molecular markers Internal Transcribed Spacer (ITS), beta-tubulin (tub2), or translation elongation factor 1 (TEF-1), are common colonisers of canvas paintings or indoor environments (e.g., Penicillium spp., Aspergillus spp., Alternaria spp.). Fungi enzymatic profiles were investigated by means of hydrolysable substrates, included in culture media or in test strips, containing components commonly used in canvas paintings. The pigment solubilisation capacity was assessed in culture media for the primary pigments and studied in relation to the organic acid secretion. Caseinases, amylases, gelatinases, acid phosphatase, N-acetyl-β-glucosaminidase, naphthol-AS-BI-phosphohydrolase, and β-glucosidase were found to be the enzymes most likely involved in the processes of substrate colonisation and breakdown of its components. Aureobasidium genus was found to hold the strongest biodeteriorative potential, followed by Cladosporium, Penicillium, Trichoderma, and Aspergillus. Blue pigment solubilisation was detected, occurring as a result of organic acids secretion. Distinct clusters were delineated considering the metabolic activities detected, indicating that fungi specialise in utilisation of certain types of substrates. It was found that both aged and modern artworks are at risk of fungal biodeterioration, due to the enzymatic activities’ diversity and intensity, pigment solubilisation capacity or pigment secretion.

“…The wet or cellar rot C. puteana is by far the most frequent species within this genus. C. puteana occurs mainly in new buildings, but also in old buildings, it can spread over the whole object, from cellar to roof (Grosser 1985;Schmidt and Huckfeldt 2011). This fungus proliferates in moist walls with cracks, occurs under boards in kitchens and bathrooms but can also develop outdoors on masts, poles and windows.…”

Wood is an important construction material, but when used incorrectly it can be subjected to deterioration by wood-destroying fungi. The brown rot producing dry rot fungus (Serpula lacrymans) is by far the most dangerous wood-destroying fungus in Europe. In the present publication, 645 fungal samples from damaged wood in the federal state of Styria (Austria) were examined and recorded by isolation date, geographical location, species identification of the wood-destroying fungus, location of damage, construction method, and age and type of building. In Styria, Serpula spp. accounted for 61.5% of damages, followed by Antrodia spp. (10.7%) and the genera Gloeophyllum (8.2%), Coniophora (3.9%) and Donkioporia (1.1%). Properties in the area of the Styrian capital Graz and old buildings were more often infested by wood-destroying fungi than houses in the rural area and new constructions.
