A team from Fudan University in Shanghai has launched the world's most comprehensive global microbial gene catalog - a database containing 303 million unigenes that will help researchers better understand the relationship between microorganisms and human health.

上海复旦大学的一个研究团队发布了全球最全面的微生物基因目录，共包含3.03亿个物种级的基因，这将帮助研究人员更好地理解微生物和人类健康之间的关系。

A paper about the catalog, "Towards the Biogeography of Prokaryotic Genes", was published in the science journal Nature on Thursday.
相关研究成果《原核生物基因的生物地理学研究》于12月16日以长文形式发表于《自然》主刊。

To collect all the genes in the global microbiome to create the catalog, a team from Fudan's Institute of Science and Technology for Brain-Inspired Intelligence - Luis Pedro Coelho, Zhao Xingming and Peer Bork created the database based on 13,000 pieces of publicly available data.
为了收集全球微生物组中的所有基因并创建目录，来自复旦大学类脑研究院的路易斯•佩德罗•科埃略、赵兴明和皮尔•伯克团队对1.3万个公开宏基因组样本进行挖掘，构建了该目录。

The researchers said microbiome research is normally carried out according to different habitats such as human microorganisms and marine microorganisms, but the catalog can analyze microbial metagenomes in different habitats on a global scale.
研究人员表示，传统微生物组研究按照人类微生物、海洋微生物等不同栖息地分别进行研究，但该目录可以在全球范围内分析不同栖息地的微生物宏基因组。
