Therefore, practice is far more important in the analysis of villagers＇ belief problems. In everyday life, villagers produce an entire set of local knowledge based on their needs and experience to life, and form various social relationships based on the shared knowledge. Narration and practice are not only the strategies that villagers often use to construct their local knowledge but also the leading ways to produce and inherit it. So it is indispensable to pay attention to the production ways and the practice, which concerning about the local belief knowledge, thus it may be better to understand their inner logic of participating the relevant ritual activities when we analyze xiangtou （香头） and kanxiang （看香） activities widely existed in rural areas of North China.展开更多
高氨氮浓度会对厌氧发酵过程中微生物群落结构和活性产生显著的影响,文章利用高通量测序手段考察高氨氮浓度条件下厌氧发酵系统中微生物的活性菌群及代谢途径的差异。结果显示,微生物群落结构随氨氮浓度发生了显著的改变,在高氨氮浓度...高氨氮浓度会对厌氧发酵过程中微生物群落结构和活性产生显著的影响,文章利用高通量测序手段考察高氨氮浓度条件下厌氧发酵系统中微生物的活性菌群及代谢途径的差异。结果显示,微生物群落结构随氨氮浓度发生了显著的改变,在高氨氮浓度条件下,主导微生物由Ruminofilibacter和Lactobacillus向Clostidium和Peptostreptococcus转变;代谢过程也出现了明显的差异,与孢子形成和细胞结构相关的代谢过程基因,如休眠与孢子形成(Dormancy and Sporulation)和细胞壁与荚膜(Cell Wall and Capsule)等相对丰度增加;与细胞分裂相关的代谢基因相对丰度降低;产甲烷过程中相应酶基因的表达量逐渐减少。这些结果表明,高氨氮浓度会改变微生物群落结构形成新的生态位,同时会改变各功能基因的表达活性,降低细胞生长和代谢相关基因表达;休眠和孢子形成,基因表达提高,有助于微生物抵抗高氨氮胁迫。展开更多
