TI  - Factual analysis of granule flotation in brewery wastewater treatment plants by 
      the fluorescence in situ hybridization method.

AB  - The factors that change the microbial distribution and consequently the flotation 
      of brewery granules were investigated using laboratory-scale upflow anaerobic 
      sludge blanket (UASB) reactors and the fluorescence in situ hybridization (FISH) 
      method. The startup operations of laboratory-scale UASB reactors fed with 
      acetate-based synthetic wastewater, in which the loading rate was maintained at 
      0.1 gCOD/gVSS/d (Run 1) and increased in a stepwise manner from 0.1 gCOD/gVSS/d 
      to 1.0 gCOD/gVSS/d (Run 2), generated methanogen colonies near the granule 
      surface, while the overloading operation at 1.0 gCOD/gVSS/d from the startup (Run 
      3) resulted in the formation of methanogen colonies deep in the granules. In each 
      run, a proportion of the granules floated when overloaded at 2.0 gCOD/gVSS/d and 
      circulation was stopped. The ratio of floating granules increased as the 
      methanogen-growing region increased. On the other hand, the Bacteria layer on the 
      granule surface, which is also considered as a possible cause of granule 
      flotation, was not formed by the inflow of other organic acids such as propionate 
      and lactate. Glucose caused formation of a 5-microm-thick surface Bacteria layer, 
      but the granules were still resistant to flotation. Interfusing of air under 
      glucose feeding caused the formation of a Bacteria layer over 50 microm thick 
      leading to granule flotation.
