摘要: 宏基因组学是不依赖人为培养技术,研究环境中全部微小生物遗传物质的总和,在研究胃肠道微生物代谢和开发瘤胃微生物资源中具有广泛的应用。动物胃肠道中存在大量共生微生物群,对宿主的生理功能、物质代谢、健康和疾病状况有重要影响。因此该技术有望解决骆驼等反刍动物代谢研究中诸多热点或难点问题。作者介绍了宏基因组文库构建和筛选流程及Roche454和Illumina高通量测序方法,并展望了宏基因组学的应用前景。

Abstract: Metagenomics is the study of communities of microbial organisms directly in their natural environments, bypassing the need for isolation and laboratory cultivation of individual species and showing strong vitality in research of the metabolic pathway and exploring the resource of rumen microbiota. There are abundance of symbiotic microbiota in the gastrointestinal tract of animals, and they are deeply associated with the well-being of the host because of affecting normal physiology, metabolism and health, as well as the development of diseases. The application of metagenomics may solve many hot and difficult issues in the research of ruminant metabolism, especially camel metabolism. Therefore, this paper reviews the construction and selection procedures, especially introduced the Roche454 and Illumina high-throughput sequencing methods. Meanwhile, the application prospects of metagenomic in communities of microbial organisms are explored.
