Temporal differences in degradation patterns of mannan and xylan epitopes in waterlogged archaeological wood

Temporal differences in the degradation of mannans and xylans during erosion bacterial decay were investigated in waterlogged archaeological wood (hard pine) using transmission electron microscopy (TEM) and immunogold labelling with monoclonal antibodies specific to mannan (LM21) and xylan (LM10). While the general degradation of hemicelluloses by erosion bacteria is well documented, comparative data on the timing and susceptibility of specific hemicelluloses remain limited. In this study, mannan epitopes were detected in the residual material of decayed tracheid cell walls, whereas xylan epitopes were not observed. These findings suggest differential susceptibility and temporal degradation patterns of mannans and xylans during erosion bacterial decay. This contributes to a deeper understanding of microbial decay mechanisms and has implications for the conservation of waterlogged archaeological wood.
