A Mariannaea fungus was isolated during investigation of an elm tree infested with unidentified beetles. Based on morphological characteristics and molecular analysis of the internal transcribed spacer rDNA sequence, the fungus was identified as Mariannaea elegans var. elegans. Fungal growth was better on malt extract agar than on potato dextrose agar and oatmeal agar. Optimal temperature and pH for growth of the fungus were 30℃ and pH 7.0, respectively. The fungus was found to have the ability to produce extracellular enzymes such as amylase, β-glucosidase, cellulase, and protease. This is first report on M. elegans var. elegans in Korea.
在对一棵被不明甲虫侵害的榆树进行调查期间，分离出了一种玛丽安娜霉菌。基于形态特征和内转录间隔区rDNA序列的分子分析，该真菌被鉴定为雅致玛丽安娜霉菌雅致变种。该真菌在麦芽提取物琼脂上的生长情况优于在马铃薯葡萄糖琼脂和燕麦片琼脂上的生长情况。该真菌生长的最适温度和pH分别为30℃和pH 7.0。发现该真菌具有产生淀粉酶、β-葡萄糖苷酶、纤维素酶和蛋白酶等细胞外酶的能力。这是韩国关于雅致玛丽安娜霉菌雅致变种的首次报道。
