Abstract

Polyphosphate-accumulating gram-negative bacteria were isolated from different anaerobic-aerobic activated sludge systems with diverse processes for enhanced biological phosphorus (P) elimination. Of 22 isolates, 10 were allocated to the genus Acinetobacter by using multiple-test systems and soluble protein and polyamine patterns. As diaminopropane (DAP) appears to be the characteristic main polyamine compound produced by Acinetobacter spp., it was used as a biomarker for the genus. The high DAP contents of representative samples from municipal wastes with enhanced biological P elimination indicated that Acinetobacter spp. can be dominant organisms in sewage treatment plants with low organic loading and nitrification and denitrification steps. Contrary to accepted opinion, sludge from treatment plants with efficient P removal and high organic loading had a low DAP content, indicating that bacteria other than Acinetobacter spp. are responsible for enhanced biological P elimination in these plants.

摘要

从不同的厌氧-好氧活性污泥系统中分离出聚磷革兰氏阴性菌，这些系统具有不同的强化生物除磷工艺。在22株分离菌中，通过多重检测系统以及可溶性蛋白和多胺模式，有10株被归类为不动杆菌属。由于二氨基丙烷（DAP）似乎是不动杆菌属产生的特征性主要多胺化合物，因此将其用作该属的生物标志物。来自具有强化生物除磷功能的城市废物的代表性样品中高含量的DAP表明，不动杆菌属可以是有机负荷低且有硝化和反硝化步骤的污水处理厂中的优势生物。与普遍观点相反，具有高效除磷和高有机负荷的处理厂的污泥中DAP含量较低，这表明除不动杆菌属以外的细菌负责这些工厂中强化生物除磷。
