List of functional groups in activated sludge.

a. Genus names with single quote marks were candidate genera that could not be classified by RDP classifier. They are kept in the final database.b. The first number indicates the sequences that could be identically classified in RDP at genus level (except for the candidate genera) and thus are kept in the final database. The second is the number of total downloaded sequences from Greengenes database. Percentage showed the portion of identically classified sequences.a. 带有单引号的属名为无法通过RDP分类器 (RDP classifier) 分类的候选属，此类属名均被保留于最终数据库中。 b. 第一个数字代表可在属水平上通过RDP分类器实现一致分类（候选属除外）并因此被保留于最终数据库中的序列条数；第二个数字为从Greengenes数据库 (Greengenes database) 下载的总序列数，百分比数值则表示实现一致分类的序列占总序列的比例。
