The efficiency of organic matter degradation in attached biomass reactors depends on the suitable selection of artificial support for the retention of bacterial communities. We have studied the growth on glass and clay beads of methylaminotrophic, acetotrophic and hydrogenotrophic methanogenic bacterial communities isolated from anaerobic reactors. Bacterial counts were performed by the standard MPN technique. Experiments were performed in 50 ml vials for 12 days at 35 degrees C. Increase in the counts of methylaminotrophic and hydrogenotrophic methanogens occurred on both glass and clay beads. The latter support material also stimulated the growth rate of methylaminotrophic methanogens.
附着生物量反应器中有机物的降解效率取决于为保留细菌群落而对人工载体的适当选择。我们研究了从厌氧反应器中分离出的甲基营养型、乙酸营养型和氢营养型产甲烷细菌群落在玻璃珠和粘土珠上的生长情况。细菌计数采用标准的最大可能数（MPN）技术进行。实验在50毫升小瓶中于35℃下进行12天。甲基营养型和氢营养型产甲烷菌的数量在玻璃珠和粘土珠上均有所增加。后一种载体材料还刺激了甲基营养型产甲烷菌的生长速率。
