Enhancing maize growth and reducing irrigation needs with extracellular polymer...
Overall, Alexandra; Moreira, Helena; Sousa, Ana S. S.; Wilfert, Philipp; Loosdrecht, Mark van; Castro, Paula M. L.; Pereira, Sofia I. A.Soil amendments and microbial inoculants can affect plant growth, water retention, and crop resilience. This study investigated the effects of two amendments, extracellular polymeric substances (EPS) and biochar, with and without bacterial inoculation, on maize (Zea mays) growth, irrigation needs, and physiological responses. Maize was cultivated in soil with 2.5 % and 5 % (w/w) of wet EPS (Kaumera®) or biochar...
Recovered granular sludge extracellular polymeric substances as carrier for bio...
Oliveira, Ana S.; Amorim, Catarina L.; Zlopasa, Jure; Loosdrecht, Mark van; Castro, Paula M. L.An increasing amount of industrial chemicals are being released into wastewater collection systems and indigenous microbial communities in treatment plants are not always effective for their removal. In this work, extracellular polymeric substances (EPS) recovered from aerobic granular sludge (AGS) were used as a natural carrier to immobilize a specific microbial strain, Rhodococcus sp. FP1, able to degrade 2-f...
Increased extracellular polymeric substances production contributes for the rob...
Oliveira, Ana S.; Amorim, Catarina L.; Mesquita, Daniela P.; Ferreira, Eugénio C.; Loosdrecht, Mark van; Castro, Paula M. L.Industrial effluents often contain organic pollutants and variable salinity levels, making their treatment challenging. The high content of extracellular polymeric substances (EPS) in the aerobic granular sludge (AGS) is thought to protect the microbial communities from stressful conditions. Ammonium and phosphate removal, EPS production, and granular morphology were assessed in a lab-scale AGS reactor operated...

Variability in the composition of extracellular polymeric substances from a ful...
Oliveira, Ana S.; Amorim, Catarina L.; Ramos, Miguel A.; Mesquita, Daniela P.; Inocêncio, Paulo; Ferreira, Eugénio C.; Loosdrecht, Mark vanWithin the framework of the circular economy, there is a need for waste management alternatives that promote the reuse of materials produced in wastewater treatment plants (WWTP). An interesting option is the recovery of extracellular substances from sludge. The variability of characteristics of potential recovered bioproducts has to be assessed in full scale operational settings. In this study, aerobic granula...
