To discover and characterize microbial diversity, approaches based on new sequencing technologies, novel isolation techniques, microfluidics, and metagenomics among others are being used. These approaches have contributed to discovery of novel genes from environmental samples, to massive characterization of functional and phylogenetic genes and to isolation of members of formerly uncultured yet ubiquitous groups like Verrucomicrobia, Acidobacteria, OP10, and methanogenic Archaea. Cheaper sequencing is key in this process by making available applications that were previously restricted to big research centers, complementing previously available methodologies and potentially replacing some of them. The new tools are reshaping the way we study the environment, increasing the resolution at which microbial communities, their complexities and dynamics, can be studied to reveal their genetic potential and their functional diversity.
为了发现和表征微生物多样性,人们正在使用基于新测序技术、新型分离技术、微流体技术和宏基因组学等方法。这些方法有助于从环境样本中发现新基因,对功能基因和系统发育基因进行大规模表征,并分离出以前未培养但普遍存在的类群成员,如疣微菌门、酸杆菌门、OP10和产甲烷古菌。更廉价的测序是这一过程的关键,它使以前仅限于大型研究中心的应用得以普及,补充了以前可用的方法,并有可能取代其中一些方法。这些新工具正在重塑我们研究环境的方式,提高研究微生物群落及其复杂性和动态性的分辨率,以揭示其遗传潜力和功能多样性。
