It is debating whether Taisui is living or not, myxomycete complex or fungi. The passage studies the 228 finding reports of Taisui in modern China. It confirms that the first finding time of Taisui in modern China is 1963, and the first reported time is 1992. Taisui has been found in 25 administrative divisions. Taisui occurs the most times in Shandong Province. Besides, provinces where Taisui has been found most times are in northern China. Finding locations of Taisui vary from place to place. Taisui is most often found in normal earth layer, with different burying depth. Taisui is mainly found through seeing, tramping, and digging. Taisui findings lack subjective motivations and are connected with the life and production of the finders. Conclusion: Taisui is an object growing in earth layer.展开更多
[目的]分析不同形态太岁中所含古菌多样性和群落结构。[方法]提取3种太岁深层组织样品的古菌DNA,进行16S r DNA PCR扩增后,利用Miseq平台进行测序统计。[结果]共得到有效序列92 849条,归类为5 161个OTU,属于2个门、5个目、11个属。21、8...[目的]分析不同形态太岁中所含古菌多样性和群落结构。[方法]提取3种太岁深层组织样品的古菌DNA,进行16S r DNA PCR扩增后,利用Miseq平台进行测序统计。[结果]共得到有效序列92 849条,归类为5 161个OTU,属于2个门、5个目、11个属。21、82、91号3个样品中,广古菌门(Euryarchaeota)都是最优势门,所占比例分别是99.67%、98.79%和99.71%。甲烷杆菌属(Methanobacterium)、甲烷短杆菌属(Methanobrevibacter)和甲烷球菌属(Methanosphaera)是丰度均排在前三位的属,所占比例之和依次是93.05%、84.16%和82.63%,其中甲烷杆菌属独自各占83.90%、47.14%、31.23%,其余两个属所占比例及其总量在不同形态太岁中不同。[结论]太岁中普遍含有古菌,优势类群为甲烷杆菌属、甲烷短杆菌属、甲烷球菌属,其在不同形态太岁所含古菌中占比范围在82.63%~93.05%之间。展开更多
