“…A comparison with previously published microscopic views of bacterial erosion of wood (Daniel and Nilsson 1986;Schmidt et al 1987;Singh et al 1990Singh et al , 1992 and wood fibres (Singh et al 1987 a) suggests that the distinctive troughs seen under the TEM (Fig. TEM observations, however, showed the various formations, e.g.…”

Light and electron microscopic observations were made of Pinus radiata wood treated to a high retention of copper-chrome-arsenate (CCA), which had failed after approximately 11 years in Service. The predominant wood cell wall degradation patterns seen under the light microscope and scanning electron microscope äs channels and shallow depressions and which were probably responsible for failure of the pole were shown by transmission electron microscopy to be caused by erosion bacteria. Although this type of wood decay is known, the predominance of attack of deeper regions of the pole by erosion bacteria was unusual and significant in terms of the ecology of wood degradirig bacteria. Soft-rot was seen in outer regions of the wood at the groundline but was very rareiy seen in deeper regions. MicroscopyThe pole had dried out on arrival at the laboratory. Small Chips of wood, 5 mm thick in a radial direction were removed with a chisel at the surface, and at depths of 20, 40, 60 and 80mm, across the diameter of discs. Transverse, radial and.tangential sections were Holzforschung / Vol. 48 / 1994 / No. 6

“…Methods such as transmission electron microscopy (TEM) and scanning electron microscopy (SEM) are well suited to reveal structural details of the degradation mechanism in bacteria infected woody tissues (Nilsson and Singh, 1984;Daniel and Nilsson, 1985;Singh and Butcher, 1986;Schmidt et al, 1987;Singh, 1989;Nilsson et al, 1992;Daniel, 1994;Schmidt and Liese, 1994;Liese et al, 1995;Schmidt, 1995;Daniel and Nilsson, 1998;Schmitt and Hoffmann, 1998;Björdal et al, 1999Björdal et al, , 2000Hoffmann et al, 2004;Schmitt and Melcher, 2004;Rehbein et al, 2008;Singh et al, 2009). To obtain topochemical information on bacterial cell wall degradation, special techniques like UV-microspectrophotometry (UMSP) must be applied.…”

“…Partial waterlogging can support the activity of soft-rot fungi and wood degrading bacteria [6]. However, when exposure conditions become anoxic due to complete waterlogging, for example, in deep ocean waters, ocean, river and lake sediments, and mud, wood is mainly degraded by erosion bacteria [7][8][9][10][11][12][13][14][15][16][17][18]. Soft-rot fungi and tunnelling bacteria may also be present but are much less frequent [13,14,16,[18][19][20].…”

This review provides information on the advances made leading to an understanding of the micromorphological patterns produced during microbial degradation of lignified cell walls of buried and waterlogged archaeological woods. This knowledge not only serves as an important diagnostic signature for identifying the type(s) of microbial attacks present in such woods but also aids in the development of targeted methods for more effective preservation/restoration of wooden objects of historical and cultural importance. In this review, an outline of the chemical and ultrastructural characteristics of wood cell walls is first presented, which serves as a base for understanding the relationship of these characteristics to microbial degradation of lignocellulosic cell walls. The micromorphological patterns of the three different types of microbial attacks—soft rot, bacterial tunnelling and bacterial erosion—reported to be present in waterlogged woods are described. Then, the relevance of understanding microbial decay patterns to the preservation of waterlogged archaeological wooden artifacts is discussed, with a final section proposing research areas for future exploration.
