Wood degradation is a complex process influenced by various biological, chemical, and environmental factors. It significantly impacts the durability and longevity of wood products and structures, necessitating effective preservation and protection strategies.
In moist and oxygenated soil, there are few treatments that enable vulnerable wood (softwood here) to resist for long against bacterial or fungal degradation Detail of sample in photo above. Wood easily degrades without sufficient preservation.
Biological wood oxidation is a composting of wood substrate which aims at generating heat—for this reason, it is also known as "compost heating". During the wood oxidation process; microorganisms, mainly bacteria and fungi, degrade wood substrate into CO 2 , H 2 O, and subsequently release heat in the presence of oxygen.
Wood decay caused by Serpula lacrymans (called true dry rot, a type of brown-rot). Fomes fomentarius is a stem decay plant pathogen Dry rot and water damage. A wood-decay or xylophagous fungus is any species of fungus that digests moist wood, causing it to rot.
Pyrolysis liquids from slow pyrolysis of bark and hemp have been tested for their antifungal activity against wood decaying fungi, showing potential to substitute the current wood preservatives [99] while further tests are still required. However, their ecotoxicity is very variable and while some are less toxic than current wood preservatives ...
Waterlogged wood is a wooden object that has been submerged or partially submerged in water and has affected the original intended purpose or look of the object. . Waterlogged wood objects can also include wood found within moist soil from archaeological sites, underwater archaeology, maritime debris, or damaged w
Acetylated wood is a type of modified wood that is produced through a chemical modification process and does not contain any toxic substances. [1] It produced from a chemical reaction (named as acetylation), involving acetic anhydride and a modification process to make wood highly resistant to biological attacks by fungi and wood-boring insects and durable to environmental conditions.
The brown-rot fungi, which are able to colonize wood by degrading cellulose, are only able to partially degrade lignin. Some bacteria also produce LMEs, although fungal LMEs are more efficient in lignin degradation. Fungi are thought to be the most substantial contributors to lignin degradation in natural systems. [1]
