During an investigation of fungi from an elm tree infested with bark beetles in Korea, one isolate, DUCC401, was isolated from elm wood. Based on morphological characteristics and phylogenetic analysis of the internal transcribed spacer and 28S rDNA (large subunit) sequences, the isolate, DUCC401, was identified as Mariannaea samuelsii. Mycelia of the fungus grew faster on malt extract agar than on potato dextrose agar and oatmeal agar media. Temperature and pH for optimal growth of fungal mycelia were 25℃ and pH 7.0, respectively. The fungus demonstrated the capacity to degrade cellobiose, starch, and xylan. This is the first report on isolation of Mariannaea samuelsii in Korea.
在对韩国受树皮甲虫侵害的榆树中的真菌进行调查期间,从榆木中分离出一个菌株DUCC401。基于形态特征以及内部转录间隔区和28S rDNA(大亚基)序列的系统发育分析,菌株DUCC401被鉴定为萨缪尔斯链格孢。该真菌的菌丝体在麦芽提取物琼脂上比在马铃薯葡萄糖琼脂和燕麦片琼脂培养基上生长得更快。真菌菌丝体最佳生长的温度和pH分别为25℃和pH 7.0。该真菌表现出降解纤维二糖、淀粉和木聚糖的能力。这是韩国关于分离出萨缪尔斯链格孢的首次报道。
