Abstract

In the study, we confirmed morphological traits and calculated the Risk Class of 25 mould species, including Tyromyces palustris, through decomposition rate of substrate for characteristic confirmation of injured microorganisms. We received the injured microorganisms in wood and it was pure cultivated. We observed growth traits and decomposition rate of substrate. Also, it allows the calculation of Risk Class to be worried in the case of growth in wooden cultural properties. As a result, Tyromyces palustris, representative of brown-rot, has the characteristics about decomposition rate of substrate - Cellulose ; more active(+++), Lignin ; more active(+++), Xylan ; more active(+++), Starch ; active(++). We classified Tyromcyes palustris as a first Risk Class and as a second Risk Class about Schizophyllum commune et al(9 species, See table 1. We look forward to offering standard data base for evaluating Risk Class as a matter of applying preventive conservation in wooden cultural properties through our study.
