Abstract

The genus Aureobasidium is wellknown as a wood-staining mold and as a black yeast-like fungi, which produces mainly dark spores or pigmented hyphae within the wood cell lumens. Nevertheless, few studies are dedicated to wood-colonizing Aureobasidium species and little is known about the wood degradation patterns of this genus. In the present study, four Aureobasidium species, including Aureobasidium melanogenum, Aureobasidium leucospermi, Aureobasidium pullulans, and an unknown Aureobasidium sp., were isolated and identified based on phylogenetic analysis. A. melanogenum and A. leucospermi were observed for the first time in Korea. The degradation pattern of Douglas-fir by Aureobasidium was observed for the first time by scanning electron microscopy (SEM). All tested Aureobasidium species except an unknown Aureobasidium sp. revealed soft-rot Type II (erosion) in sapwood pine.
