Micromorphological and ultrastructural investigation showed diverse forms of biological as well as non-biological deterioration. Wood from a cabinet in the Thomas A. Edison Laboratory Museum, Fort Myers, Florida (40–60 years old) appeared soft and shredded. The unusual deterioration resulted from a chemical spill of caustic substance(s) that gradually delignified the wood. Middle lamellae were removed from the woody cell walls leaving detached secondary wall layers. Samples of furniture and tomb structure from Tumulus MM, Gordion, Turkey (700 <span>BC</span>), considered to be the tomb of King Midas, had extensive soft rot. Extensive cavity formation was observed throughout the S<sub>2</sub> layers of secondary walls. Egyptian samples (3000-1000 <span>BC</span>) were attacked primarily by brown rot fungi. Localized areas of severely degraded wood contained cells that appeared porous and lacked structural intergrity. The lignified residue that remained fragmented into dust-like particles. An unusual form of soft rot with cavities within the S<sub>1</sub> layer of the secondary wall also was found in one Egyptian object. Ancient buried, waterlogged wood (10 000–4000 <span>BC</span>) was degraded by tunneling and erosion forms of bacteria. Minute cavities and a diffuse attack of the cell wall occurred. These ultrastructural results provide information concerning the current condition of the wood and also a chronology of past degradative processes that are essential to ascertain the most appropriate methods of conservation.</p></div>","PeriodicalId":13629,"journal":{"name":"International Biodeterioration","volume":"28 1","pages":"Pages 3-22"},"PeriodicalIF":0.0,"publicationDate":"1991-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0265-3036(91)90030-U","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87228068","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Communities of mosses grew preferentially on mortars with pronounced disintegrating effects due to penetration of rhizoids. Both lichens and bryophytes lead to mechanical and chemical damage to stonework. This represents a stage in the succession which gives rise to the later invasion by vascular plants, whose roots cause important deterioration in the structure of the buildings, mainly roofings, tiles, guttering, etc.</p></div>","PeriodicalId":13629,"journal":{"name":"International Biodeterioration","volume":"28 1","pages":"Pages 151-163"},"PeriodicalIF":0.0,"publicationDate":"1991-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0265-3036(91)90040-X","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80530710","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
