Effect of presence or absence of Margaritifera laevis or Margaritifera togakushiensis (ML/MT) on the amount of inorganic compounds and bacterial flora composition of neighboring biofilms (control: C). (a) Ammonia nitrogen concentration, (b) Nitrate nitrogen concentration, (c) Bacterial flora composition. Error bars indicate standard deviation. The * in (c) is significantly different by Student's t-test (p <0.05). From the data of (a) and (b), the concentration of inorganic nitrogen in the river biofilm is low in the presence of Margaritifera, and from the data of (c), the distribution of photosynthetic bacteria in the biofilm is particularly different. These findings suggest that the energy metabolism of the organisms constituting the biofilm are different.
