Abstract：
In the mid-1990s, the category \'Candidatus\' was established for putative taxa of as yet uncultivated prokaryotes. The status of \'Candidatus\' is not formally included in the rules of the International Code of Nomenclature of Prokaryotes. Thus, \'Candidatus\' names do not have standing in the nomenclature. Curated annotated lists of \'Candidatus\' names (not including phyla) have been published since 2020. By April 2021, about 2700 names of \'Candidatus\' taxa had been published. The International Committee on Systematics of Prokaryotes recently rejected proposals to allow gene sequence data as nomenclatural types. An alternative code for naming uncultivated microorganisms (the \'SeqCode\') is now being developed for naming the majority of prokaryotes that are as yet uncultivated. In the opinion of the author, there is no need for such a code, as the existing system, with nomenclature quality control also for \'Candidatus\' names, fulfills the needs. Computer programs such as GAN which generates large numbers of correctly formed names from the short lists of Latin and Greek word elements and Protologger that produce descriptions directly from genome sequences will become important in the future for automated naming and description of large numbers of \'Candidatus\' taxa from metagenomic and single cell genome data. However, the formation of interesting and meaningful names is encouraged whenever possible.
摘要：
在1990年代中期,“Candidatus”类别是为尚未培养的原核生物的推定分类群建立的。“Candidatus”的状态未正式包含在《国际原核生物命名法》的规则中。因此，\'Candidatus\'名称在命名法中没有代表。自2020年以来，已发布了“Candidatus”名称（不包括门）的精选注释列表。到2021年4月，已经发布了大约2700个“Candidatus”类群的名称。国际原核生物系统学委员会最近拒绝了允许基因序列数据作为命名类型的提议。现在正在开发一种命名未培养微生物的替代代码（“SeqCode”），用于命名大多数尚未培养的原核生物。在作者看来,不需要这样的代码，作为现有的系统，还对“候选人”名称进行命名质量控制，满足需求。诸如GAN之类的计算机程序可以从拉丁语和希腊语单词元素的简短列表中生成大量正确形成的名称，而Protologger则可以直接从基因组序列中生成描述，这在将来对于从宏基因组和单细胞基因组数据中自动命名和描述大量“Candidatus”分类群的重要性。然而,鼓励尽可能形成有趣和有意义的名字。
