Abstract

Tricholoma matsutake has been the most valuable ectomycorrhizal fungi in Asia because of its unique flavor and taste. However, due to the difficulty of artificial cultivation, the cultivation of T. matsutake has relied on natural growth in forests. To cultivate the T. matsutake artificially, microorganisms in fairy rings were introduced. In this study, we isolated 30 fungal species of microfungi from the soil of fairy rings. Among them, one single fungal strain showed a promoting effect on the growth of T. matsutake. The growth effect was confirmed by measuring the growth area of T. matsutake and enzyme activities including α-amylase, cellulase, and β-glucosidase. In comparison with control, microfungal metabolite increased the growth area of T. matsutake by 213% and the enzyme activity of T. matsutake by 110-200%. The isolated fungal strain was identified as Penicillium citreonigrum by BLAST on the NCBI database. The Discovery of this microfungal strain is expected to contribute to artificial cultivation of T. matsutake.

青霉菌对松茸菌丝体生长的促进作用。

松茸以其独特的风味和口感成为亚洲最有价值的外生菌根真菌。然而，由于人工栽培的困难，松茸的栽培一直依赖于森林中的自然生长。为了人工培养松茸，引入了仙女环中的微生物。在本研究中，我们从仙女环的土壤中分离出30种微真菌。其中，单一菌株对松茸生长有促进作用。通过测量松茸的生长面积和包括α-淀粉酶、纤维素酶和β-葡萄糖苷酶在内的酶活性来证实生长效果。与对照相比，微真菌代谢产物使松茸的生长面积增加了213%，酶活性增加了110-200%。经NCBI数据库BLAST鉴定，该菌株为青霉菌。这种微真菌菌株的发现有望为松茸的人工栽培做出贡献。

期刊介绍： Mycobiology is an international journal devoted to the publication of fundamental and applied investigations on all aspects of mycology and their traditional allies. It is published quarterly and is the official publication of the Korean Society of Mycology. Mycobiology publishes reports of basic research on fungi and fungus-like organisms, including yeasts, filamentous fungi, lichen fungi, oomycetes, moulds, and mushroom. Topics also include molecular and cellular biology, biochemistry, metabolism, developmental biology, environmental mycology, evolution, ecology, taxonomy and systematics, genetics/genomics, fungal pathogen and disease control, physiology, and industrial biotechnology using fungi.
