Microbiome adaptation of aerobic granular sludge allows process resilience duri...
Miranda, Catarina; Maia, Alexandra S.; Tiritan, Maria Elizabeth; Castro, Paula M. L.; Amorim, Catarina L.Coastal wastewater treatment plants often face multiple stressors (e.g., pharmaceuticals and oscillating seawater levels) simultaneously, and their combined effects on biological treatment systems are still largely underestimated. In this study, an aerobic granular sludge (AGS) reactor was challenged over a four-month period with wastewater that had daily fluctuations in seawater content (7.5 to 22.5 g/L) and o...
Shifts in aerobic granular sludge bacteriome driven by seawater intrusion in wa...
Miranda, Catarina; Castro, Paula M. L.; Amorim, Catarina L.High salinity levels in wastewater treatment plants (WWTPs) can be attributed to multiple sources, including seawater intrusion in wastewater streams. In coastal WWTPs, this phenomenon is becoming more frequent, causing transient salinity shocks on the microbial populations involved in the treatment process. Aerobic granular sludge (AGS) has emerged as a revolutionary technology that has been adopted worldwide ...
CCL2 expression predicts clinical outcomes and regulates E-cadherin and angioge...
Silva, Ana Luísa; Barry, Sayka; Lopes-Pinto, Mariana; Joaquim, Rita; Miranda, Catarina; Reis, Fábio; Miranda, Micaella; Matos, Paulo; Suleyman, OnizThe crosstalk between tumour cells and microenvironment components in pituitary neuroendocrine tumours (PitNETs), including chemokines, may impact tumour behaviour and clinical outcomes. CCL2 was previously identified as a key chemokine in PitNETs, but its role remains unknown. We aimed to study the role of CCL2 in defining the phenotype and clinical outcomes of PitNETs and in regulating macrophage chemotaxis, ...
Wastewater stressors shape the microbiome of aerobic granular sludge
Miranda, Catarina; Maia, Alexandra S.; Tiritan, Maria Elizabeth; Amorim, Catarina L.; Castro, Paula M. L.Aerobic granular sludge (AGS) is a revolutionary biological treatment technology, which, due to its competitive advantages, has been increasingly implemented in full-scale wastewater treatment plants (WWTPs). WWTPs are frequently challenged by multiple stressors, including pharmaceuticals and fluctuating salinity, which not only increase the complexity of wastewater but also impair the biological treatment perf...
Unveiling the agronomic potential of extracellular polymeric substances recover...
Amorim, Catarina L.; Pereira, Sofia I.A.; Sousa, Ana S. S.; Wilfert, Philipp; Loosdrecht, Mark van; Martins, António; Castro, Paula M. L.Background: Extracellular polymeric substances (EPS) recovered from waste aerobic granular sludge (AGS) generated during wastewater treatment represent a promising route for resource recovery. As valuable biopolymers, EPS have garnered special attention across multiple sectors, particularly agriculture, although their benefits in this field remain understudied. This study assessed the agronomic potential of EPS...

Amorim, Catarina L.; Pereira, Sofia I. A.; Sousa, Ana S. S.; Wilfert, Philipp; Loosdrecht, Mark van; Martins, António; Castro, Paula M. L.Extracellular polymeric substances (EPSs) are biopolymers that can be recovered from waste aerobic granular sludge (AGS) generated in wastewater treatment plants (WWTPs). These biopolymers represent a valuable resource with attractive attributes, making them suitable for applications across different sectors. In agriculture, EPSs have attracted growing interest, although their beneficial effects are still under...

Amorim, Catarina L.; Pereira, Sofia I. A.; Sousa, Ana S. S.; Wilfert, Philipp; Loosdrecht, Mark van; Martins, António; Castro, Paula M. L.Extracellular polymeric substances (EPS) can be recovered from waste aerobic granular sludge (AGS) generated during biological wastewater treatment. These biopolymers are rich in organic carbon and nutrients and can improve the water-holding capacity of soils, making them suitable for agricultural applications.
Stable nutrient removal from wastewater with fluctuating seawater content ensur...
Miranda, Catarina; Castro, Paula M. L.; Amorim, Catarina L.Seawater intrusion in coastal regions can alter the wastewater composition, threatening the microbial commu nities in wastewater treatment processes. An aerobic granular sludge (AGS) system was challenged by fluctua tions in wastewater salinity levels promoted by seawater intrusion events for 286 days, divided into two stages. During stage I, the seawater content in wastewater increased stepwise, and over stage...
Exploring the potential of a waste-derived bone char for pharmaceuticals adsorp...
Miranda, Catarina; Scalera, Francesca; Piancastelli, Andreana; Pullar, Robert C.; Tiritan, Maria Elizabeth; Piccirillo, Clara; Castro, Paula M. L.In this study, the effect of salinity in wastewater on the adsorption capacity of a bone char material prepared through pyrolysis of tuna bones at 1000 °C was investigated for two pharmaceuticals, tramadol (TRA) and venlafaxine (VNF), both contaminants of emerging concern. This is the first time that the adsorption efficiency of a bone char-type material was tested in such conditions. The Tuna Bone Char (TBC) w...
The potential of tuna bone char as a sorbent material for pharmaceuticals remov...
Miranda, Catarina; Piccirillo, Clara; Tiritan, Maria Elizabeth; Castro, Paula M. L.; Amorim, Catarina L.The extensive consumption of pharmaceuticals combined with the limited removal capacity of wastewater treatment processes result in their continuous accumulation in water bodies which can adversely affect the environment and human health. Thus, efficient strategies to avoid the release of these persistent compounds in the environment are needed. The adsorption-based processes are promising methodologies to redu...
