The Role of Ascomycete and Imperfect Fungi in Effecting the Degradation of Wood (O Roli Sumchatykh i Nesovershennykh Gribov v Razrushenii Drevesiny),

Abstract

The effect of micromycetes on wood is very poorly understood and has received very little attention in the literature. In the study it was found that micromycetes represents a unified group with numerous ecological modifications which can be extremely similar in species composition. The numerous modifications are a result of their high flexibility, which makes it possible for them to reorganize their enzymatic system, adapting it to changing conditions. In wood, as the most readily available nutrients of the protoplast are used, the micromycetes, can convert to the use of less readily accessible nutrition sources, such as the lignin-cellulose complex of cell walls and thereby cause rot. With respect to the frequency of their occurrence, micromycetes as wood degraders considerably surpass macromycetes and yield to them only with respect to the rate at which the process transpires. In economic respects, micromycetes must be regarded as of great importance, and the antiseptics used for the protection of wood must be evaluated not only with respect to their effect on macromycetes, as is done at present, but also with respect to micromycetes.
