松口蘑是一种以赤松为寄主的担子菌，能形成外生菌根。它的子实体，日本的“松茸”，是一种可食用的，非常珍贵的蘑菇，它生长在一个被称为仙女环的圆圈中。在T的仙女环下。松茸，一种白色的菌丝-土壤聚集带，在日本被称为“shiro”，发展。四郎的前部是一个活跃的菌根区，其功能是从土壤和根系中收集养分，以滋养仙女环。细菌和产孢真菌从四郎前线减少，而它们在四郎前线内外增加。大原证明了shiro front具有抗菌活性，但抗菌物质50年来一直未被发现。我们已经确定了抗微生物物质为（草酸）铝酸盐络合物，称为草酸和磷酸铝释放可溶性磷的反应产物。该复合体保护Shiro免受微生物的侵害，并有助于其发展。
Tricholoma matsutake, a basidiomycete, forms ectomycorrhizas withPinus densifloraas the host tree. Its fruiting body, “matsutake” in Japanese, is an edible and highly prized mushroom, and it grows in a circle called a fairy ring. Beneath the fairy ring ofT. matsutake, a whitish mycelium-soil aggregated zone, called “shiro” in Japanese, develops. The front of the shiro, an active mycorrhizal zone, functions to gather nutrients from the soil and roots to nourish the fairy ring. Bacteria and sporulating fungi decrease from the shiro front, whereas they increase inside and outside the shiro front. Ohara demonstrated that the shiro front exhibited antimicrobial activity, but the antimicrobial substance has remained unidentified for 50 years. We have identified the antimicrobial substance as the (oxalato)aluminate complex, known as a reaction product of oxalic acid and aluminum phosphate to release soluble phosphorus. The complex protects the shiro from micro-organisms, and contributes to its development.
