单扩增基因组 (SAG) 和宏基因组组装基因组 (MAG) 的组装导致古细菌和细菌成员的基于基因组的发现激增，从而需要制定未培养微生物的命名指南。国际原核生物命名法（ICNP）仅将培养物视为“典型材料”，从而阻止对未培养生物的命名。在本共识声明中，我们提出了解决这一命名难题的两种可能途径。一种选择是采用先前提出的对 ICNP 的修改，以将 DNA 序列识别为可接受的类型材料；另一种选择是为未开化的古生菌和细菌创建命名代码，将来最终可能会与 ICNP 合并。无论采取何种路径，我们认为科学界现在需要采取行动，为未培养的分类单元的命名制定一致的规则，以提供清晰度和稳定性，并有效传达微生物多样性。在这份共识声明中，作者讨论了未培养的原核微生物的命名问题，由于缺乏模式材料或培养的代表，这些微生物目前没有正式的命名系统，并提出了两项建议，包括将DNA序列识别为模式材料。
The assembly of single-amplified genomes (SAGs) and metagenome-assembled genomes (MAGs) has led to a surge in genome-based discoveries of members affiliated with Archaea and Bacteria, bringing with it a need to develop guidelines for nomenclature of uncultivated microorganisms. The International Code of Nomenclature of Prokaryotes (ICNP) only recognizes cultures as 'type material', thereby preventing the naming of uncultivated organisms. In this Consensus Statement, we propose two potential paths to solve this nomenclatural conundrum. One option is the adoption of previously proposed modifications to the ICNP to recognize DNA sequences as acceptable type material; the other option creates a nomenclatural code for uncultivated Archaea and Bacteria that could eventually be merged with the ICNP in the future. Regardless of the path taken, we believe that action is needed now within the scientific community to develop consistent rules for nomenclature of uncultivated taxa in order to provide clarity and stability, and to effectively communicate microbial diversity.In this Consensus Statement, the authors discuss the issue of naming uncultivated prokaryotic microorganisms, which currently do not have a formal nomenclature system due to a lack of type material or cultured representatives, and propose two recommendations including the recognition of DNA sequences as type material.
