Bacteria are cosmopolitan microbes. They can live everywhere and anywhere as long as the environment is capable for them to live. Moreover, they can live in the organisms and microorganisms, such as mushroom/fungi. In my study, I learn about the bacteria in/on fungal mycelial isolates. The bacteria can be divided into two types as Exo- and Endo-Hyphal Bacteria. During my research in Tottori, I found many bacteria isolated from ectomycorrhizal fungal isolates. They had the uniqueness each other. I called these bacteria as culturable hyphal bacteria. I am sure that many bacteria livings in/on the fungal isolates, but mostly maybe they are unculturable bacteria.

Previously, my bachelor’s degree field was about isolation ectomycorrhizal fungi on serpentine (harsh/toxic) soil. And I did the postulate Koch to confirm the isolate can penetrate as ectomycorrhizal fungi to the plant. Then, my master’s degree field was about the taxonomy using ecological, morphological, molecular, and biological species concepts for fungal subject as in Zygomycota. From my previous fields, I used and compiled the skills for my Doctoral degree field here. I found my passion in mycology field.

Being the doctoral student in Tottori University makes my passion and interest of mycology to become more confident. During my doctoral research that I found the bacteria, now I am thinking about the role of the bacteria for the fungal host and non-fungal host too. The result will explain us about the relationship between the bacteria and the fungi as consortium phenomenon. As a researcher here, I investigate the interaction of the microorganisms.
