FUNGISTATIC AND FUNGICIDAL ACTION OF 6 BIOCIDES APPLIED IN THE TREATMENT OF CONTAMINATED ARCHAEOLOGICAL WOOD

Numerous microorganisms grow on waterlogged archeological woods leadin g to their deterioration. Microbial proliferation should be avoided by the use of one or several biocides. In a previous study, we surveyed the mycoflora found in a waterlogged boat from the end of the 17th cen tury, discovered in 1990 near Bordeaux (Bouliac, France). In this work , 7 species, representative of the different taxonomic groups isolated and identified from small wood samples, have been checked for their s ensitivity towards six commercial biocides containing various classes of active compounds. The minimal inhibitory concentrations and the min imal lethal concentrations have been determined for each biocide.
