Microbial population in rotten living body ofSalix matsudana

Abstract

The microbial population in rotten living body ofSalix matsudana caused byTrametes suaveolens (L.) was researched. 11 bacteria species (1 species ofBacillus, 2 species ofClostridium and 8 species of non-brood-cell bacteria), 1 species ofActinomyces that belongs to Lavendulac, 8 species of fungi and 6 species ofTrichoderma were isolated from rotten trunk. The hyphae ofTrametes suaveolens mainly existed between rotten sections and discoloration sections. In over-rotten section and healthy section the fungi (Trametes suaveolens) were not isolated. The microbes that lived in the discoloration section were the most in kinds and number and they were the pioneer microbes of wood rotting. Only after they dwelled in wood and eliminated its rot-resistance, could wood-rotting fungi invade wood and caused wood-rotting.
