摘要：

从处理糖蜜酒精废液的UASB反应器颗粒污泥中筛选出优势菌株,并对优势菌的生态位、代谢产物及降解性能进行了研究.结果显示,优势菌种组成的复合菌群有很宽的生态位,且在不同的生态位都有相应的优势菌种,具有生态位的多样性和稳定性;复合菌群能通过调节代谢产物适应外界条件的改变,并逐渐使外界环境向菌群适宜的生态位迁移.通过温度、COD、pH等生态因子对复合菌群降解性能影响的研究,得出了复合菌群适宜的降解条件,为优势菌群的应用奠定了基础.

关键词: 糖蜜酒精废液, 优势复合菌群, 生态位, 降解性能

Abstract:

Dominant bacterial strains have been screened out from UASB reactor granular sludge which was used in the treatment of molasses alcohol wastewater,and the ecological niche,metabolic products,and degradation capacity of dominant bacteria are studied. The results show that the compound florae,which consist of dominant strains,have wide ecological niches. In different niches,compound florae have corresponding dominant strains. The compound flore have the diversity and stability of niches. Compound florae can accommodate the changes of external conditions by adjusting metabolic products,and make the external environment move gradually to the niche that is suitable for florae. The degradation conditions suitable for compound florae have been obtained through the research on the effects of ecological factors,such as temperature,COD and pH on the degradation capacity of compound florae,laying foundations for the application of dominant florae.Dominant bacterial strains have been screened out from UASB reactor granular sludge which was used in the treatment of molasses alcohol wastewater,and the ecological niche,metabolic products,and degradation capacity of dominant bacteria are studied.
