“…Their results were in agreement with those of Gori et al (2011) andvon Schulthess andGujer (1996) in terms of COD/N ratio and N 2 O production. Specifically, these researchers showed that the higher TSS efficiency removal in the primary clarifier decreased the CO 2 on-site emissions (due to the lower CO 2 production during endogenous and respiration biomass growth) and the CO 2 off-site emission (due to the lower aeration requirement) ( Table 1).…”

“…The Corynebacterium, Aquaspirillum, Alteromonas, and Shewanella isolates identified by the Biolog system reduced the NO 3 Ϫ to N 2 O. N 2 O emission by Corynebacterium sp. may be due to a high nitrite concentration (Table 3), which causes a high turnover for nitrite reductase and consequently a high N 2 O production rate [4,29]. Aquaspirillum, Alteromonas, and Shewanella isolates did not accumulate NO 2 Ϫ as substrate for the denitrification respiratory chain.…”

In this study, phosphate-accumulating bacteria achieved complete phosphate removal in two different systems: an anaerobic-anoxic sequencing batch reactor and an anaerobic-aerobic sequencing batch reactor. This result shows that phosphate-accumulating bacteria in the A2 SBR can use nitrate as terminal electron acceptor instead of oxygen. Phosphate-accumulating bacteria accumulated phosphate with a rates between 30 and 70 mg P/L/h in the A/O SBR and between 15 and 32 mg P/L/h in the A2 SBR. Twenty denitrifying isolates were screened from A2 SBR and nine from A/O SBR. Identification of these isolates by the Biolog system and the API 20 NE identification kit revealed that the most active denitrifiers in both SBRs reactors were species of Ochrobactrum, Pseudomonas, Corynebacterium, Agrobacterium, Aquaspirillum, Haemophilus, Xanthomonas, Aeromonas, and Shewanella. The most active phosphate accumulating and denitrifying bacteria were identified as Agrobacterium tumefaciens B, Aquaspirillum dispar, and Agrobacterium radiobacter. This study showed that the active phosphate accumulating-bacteria were also the most efficient denitrifying bacteria in both reactors.

“…It has been proposed to achieve 76 this goal through modelling denitrification as a four-step process, using NO3 -, NO2 -, NO, and as a separate and independent oxidation-reduction reaction (Figure 1-a), and reaction-specific 89 kinetics are applied. Many of the multiple step denitrification models have adopted such 90 structure (e.g., Ni et al (2011), Schulthess and Gujer (1996). …”
