摘　　要：厌氧消化酒精废醪中的产甲烷细菌数量较多,组成较杂;通常情况下,甲烷杆菌占优势,环境条件如温度,pH以及废水成份的变化会导致优势种群的更替;冷藏是保存产甲烷细菌的有效方法,浅盘静止曝氧会引起厌氧活性污泥中的产甲烷菌数急剧下降。This result shows that there exists high guantity and various types of Methanogens in anaerobic digestion of alcohol-producing wastewater.In general, the dominant Methanogens are Methanobacterum, but the type of dominant Methanogens will change with the environmental conditions (such as temperature, pH, or composition of wastewater) . Methanogens are stored effectively by cold storage If Methanogens are exposed to oxygen, they will decrease in number rapidly.
