“…So far, most of the research has focussed on photogranule initiation and microbial community assembly (Abouhend et al, 2020; Ansari et al, 2021; Ji et al, 2020; Safitri et al, 2021; Sales et al, 2022; Volkova et al, 2020; Zhu et al, 2023). Little is known about the effect of varying wastewater characteristics, and so far, there are no studies on nitrogen limitation.…”

Wastewater characteristics can vary significantly, and in some municipal wastewaters the N:P ratio is as low as 5 resulting in nitrogen-limiting conditions. In this study, the microbial community, function, and morphology of photogranules under nitrogen-replete (N+) and limiting (N−) conditions was assessed in sequencing batch reactors. Photogranules under N− condition were nitrogen deprived 2/3 of a batch cycle duration. Surprisingly, this nitrogen limitation had no adverse effect on biomass productivity. Moreover, phosphorus and chemical oxygen demand removal were similar to their removal under N+ conditions. Although performance was similar, the difference in granule morphology was obvious. While N+ photogranules were dense and structurally confined, N− photogranules showed loose structures with occasional voids. Microbial community analysis revealed high abundance of cyanobacteria capable of N 2 -fixation. These were higher at N− (38%) than N+ (29%) treatments, showing that photogranules could adjust and maintain treatment performance and high biomass productivity by means of N 2 -fixation.
