“…Used probes are listed in Table 1S (supplementary information) and details are available at probeBase [20]. The criteria used for the selection of the FISH probes was the identification of filamentous bacteria, based on Nielsen et al [9], according to Table 1 …”

“…R1 was operated under relatively high F/M ratio (around 1 kg COD/(kg VSS·d)), and this was reported as one of the possible factors that caused the growth of S. Natans [9]. However, R2 and R3 were operated at lower F/M values that are favorable for the growth of most of the filamentous species [8,32].…”

“…Nowadays, the identification based on morphotypes is known to be frequently inadequate for the reliable identification of many filamentous bacteria, since one morphotype can embrace several phylogenetically very different organisms [9]. For example, previous studies have revealed that the Nostocoida limicola morphotypes are affiliated to members as diverse as the phyla Chloroflexi, Firmicutes, and Actinobacteria, the class Alphaproteobacteria and the order Planctomycetales.…”

Filamentous bacteria are associated to biomass settling problems in wastewater treatment plants. In systems based on aerobic granular biomass they have been proposed to contribute to the initial biomass aggregation process. However their development on mature aerobic granular systems has not been sufficiently studied. In the present research work filamentous bacteria were studied for the first time after long term operation (up to 300 days) of aerobic granular systems. Chloroflexi and Sphaerotilus natans have been observed in a reactor fed with synthetic wastewater. These filamentous bacteria could only come from the inoculated sludge. Thiothrix and Chloroflexi bacteria were observed in aerobic granular biomass treating wastewater from a fish canning industry. Meganema perideroedes was detected in a reactor treating wastewater from a plant processing marine products. As a conclusion the source of filamentous bacteria in these mature aerobic granular systems fed with industrial effluents was the incoming wastewater.

From macro to lab-scale: Changes in bacterial community led to deterioration of EBPR in lab reactor

et al. 2013

A laboratory scale sequencing batch reactor (SBR), fed with synthetic wastewater containing a mixture of organic compounds, was operated for nearly six months. Despite maintaining the same operational conditions, a deterioration of enhanced biological phosphorus removal (EBPR) occurred after 40 days of SBR operation. The Prel/Cupt ratio decreased from 0.28 to 0.06 P-mol C-mol−1, and C requirements increased from 11 to 32 mg C h−1 g−1 of mixed liquor suspended solids. A FISH analysis showed that the percentage of Accumulibacter in an overall community of polyphosphate accumulating organisms (PAOs) and glycogen accumulating organisms (GAOs) dropped from 93% to 13%. An increase in abundance of Gammaproteobacteria (from 2.6% to 22%) and Alphaproteobacteria (from 1.8% to 10%) was observed. The number of Competibacter increased from 0.5% to nearly 9%. Clusters 1 and 2 of Defluviicoccus-related GAOs, not detected before deterioration, constituted 35% and 27% of Alphaproteobacteria, respectively. We concluded that lab-scale experiments should not be extended implicitly to full-scale EBPR systems because some bacterial groups are detected mainlyin lab-scale reactors. Well-defined, lab-scale operational conditions reduce the number of ecological niches available to bacteria.

“…En los sistemas de depuración de agua residual se asume de manera general que estos dos pasos son realizados por bacterias amonioxidantes (AOB) y bacterías nitritoxidantes (NOB), respectivamente. No se tiene conocimiento de la existencia de organismos capaces de realizar la oxidación completa del amonio hasta nitrato (Nielsen et al, 2009). …”
