DNA analysis as tool for identification of bacteria in archaeological waterlogged wood
2014
Abstract In this work molecular techniques were applied in order to integrete the results obtained by Optical (OM) and Scanning Electron (SEM) Microscopy, to understanding and assessing the changes in the anatomical structure of archaeological waterlogged wood (Pinus sp.) induced by bacteria colonization. Observation of wooden thin sections revealed by OM showed the presence of black and dark -brown areas (must probably due to sulphur compounds) and mineral concretions. The SEM micrographs revealed a specific cell wall alteration attributable to bacterial activity and abundant pyrite framboids (as single structure or clustered). The presence of sulfur compounds in archaeological waterlogged…
