Tissues and mucus of acorn worms are known to contain phenolic compounds, which inhibit activity of aerobic bacteria. Mycobiota of tissues, the body surface, and burrows were studied for the acorn worm Saccoglossus mereschkowskii (Wagner, 1885). Three fungal species were found in the plating of intestine samples. Seven fungi were isolated from samples washed out from the S. mereschkowskii body surface. Five species were found in burrow samples; and 15, in sediment samples from the S. mereschkowskii habitat. Cultures of intact specimens, gill bars, and axial organ did not reveal the growth of mycelial fungi. A potential fungistatic effect was consequently assumed for acorn worm tissues.
已知柱头虫的组织和黏液中含有酚类化合物，这些化合物会抑制需氧细菌的活性。对瓦格纳1885年发现的梅氏柱头虫（Saccoglossus mereschkowskii）的组织、体表和洞穴中的真菌群落进行了研究。在肠道样本的平板培养中发现了三种真菌。从梅氏柱头虫体表冲洗出的样本中分离出七种真菌。在洞穴样本中发现了五种真菌；在梅氏柱头虫栖息地的沉积物样本中发现了15种真菌。完整标本、鳃条和轴器官的培养物未发现丝状真菌生长。因此推测柱头虫组织具有潜在的抑菌作用。
