Abstract
The present long-term study (about 1,100 days) monitored the diversity of methanogens during the mesophilic, anaerobic digestion of beet silage. Six fermentor samples were analyzed by ribosomal RNA gene restriction analysis, fluorescence in situ hybridization, and fluorescence microscopy. Hydrogenotrophic methanogens dominated within the population in all samples analyzed. Multidimensional scaling revealed that a rapid decrease in hydraulic retention time resulted in increased species richness, which in turn led to slightly higher CH(4) yields.
摘要
本长期研究（约 1100 天）监测了嗜温、厌氧消化甜菜青贮过程中产甲烷菌的多样性。通过核糖体 RNA 基因限制性分析、荧光原位杂交和荧光显微镜分析了 6 个发酵罐样品。在所有分析的样品中，氢营养型产甲烷菌在种群中占主导地位。多维尺度分析显示水力停留时间的快速缩短导致了物种丰富度的增加，进而导致 CH4 产量略有提高。
