| Summary: | The effect of electrostatic and hydrophobic properties of microbes in anaerobic sludge on immobilization to support materials was examined. The most popular aceticlastic methanogen, Methanosaeta concilii, was uncharged and hydrophobic. Methanosarcina barkeri of a methyltrophic methanogen, and acidogens cultivated selectively from anaerobic sludge, were negatively charged and hydrophobic. Immobilized microbes on support materials were incubated with sodium acetate. Methanogens were dramatically immobilized to bamboo charcoal, in contact with hydrophilic alumina. Methanosaeta-like microbes were immobilized to bamboo charcoal. These results indicate that the hydrophobic and negatively-charged support material that can suppress the immobilization of microbes except for Methanosaeta species is suitable for selective immobilization of Methanosaeta species, which is the most important microbe in methane fermentation.† This paper, appeared originally in Japanese in J.
