- Aerobic granules synthesized with EPS and degrading strain Rhodococcus sp. FP1 for industrial wastewater treatmentPublication . Oliveira, Ana; Amorim, Catarina L.; Zlopassa, Jure; Lin, Yuemei; van Loosdrecht, Mark; Castro, Paula M. L.Background: Aerobic granular sludge-sequencing batch reactors (AGS-SBR) have been introduced as a promising and innovative wastewater treatment system economically outcompeting the conventional activated sludge system. AGS is considered a special case of suspended biofilms, composed of self-immobilized microorganisms that form spherical sludge aggregates. Microorganisms are embedded in a self-produced extracellular polymeric substances matrix thus avoiding the need of any carrier. Many synthetic organic chemicals or metabolites are being released directly into the environment after wastewater treatment processes, which are not conceived to remove them from the effluents. In spite of the AGS tolerance to toxicity, the indigenous microbial communities in biotreatment processes may not be effective in removing recalcitrant pollutants. Bioaugmentation strategies, which consists of adding specific microorganisms to the system can be a solution to overcome the difficulty to eliminate certain compounds in wastewaters. However, it is still not a well-established strategy and deserves attention to become a promising alternative. This work aimed to synthesize strong aerobic granules using EPS (extracted from AGS) and a specialized bacterial strain capable of degrading 2-fluorophenol, with the aid of specific substances to increase the cross-linking potential of EPS. Conclusions: Substance 1 was not efficient in improving the strength of the granules, due to concentration or inability to promote the crosslinking of EPS; Granules from mixture 6 were the most similar in terms of strength to the Utrecht granules. The source of EPS affected the strength of the granules, even with conditions similar to mixture 6 Control beads from mixture 7 showed to be weaker than the ones from mixture 6, reinforcing that EPS was a key component to increase the strength of the produced granules. EPS composition and concentration are important to produce strong granules that can be further used in bioaugmentation.
- Algarve's PGI citrus essential oils: unlocking the potential of food industry by-productsPublication . Rodrigues, Cristina V.; Magalhães, Daniela; Vilas-Boas, Ana A.; Pintado, ManuelaWorldwide, the processing of citrus juices generates elevated amounts of waste (around 120 million tons, annually), due to the discard of these fruits by-products, such as peels, seeds and pulp, leading to an unprecedented environmental burden. Portugal's citrus fruits cultivated under the Protected Geographical Indication (PGI) designation, particularly, constitute a significant agricultural sector, which resulted in a production of approximately 398.83 thousand tons, in 2019 [1]. Nevertheless, the processing of these citrus results in wasting between 45% and 50% of the fruit, and contributes to environmental issues such as water and land pollution [2, 3]. Orange (Citrus sinensis) and lemon (Citrus limon) peels, for instance, contain valuable bioactive compounds such as polyphenols, essential oils, and fiber, which can be repurposed for novel food, pharmaceutical and cosmetic applications [2,3]. Regarding these promising compounds, citrus peels essential oils (EO’s) have gained increasing attention for their diverse applications within the food preservation area, due to their properties, such as potential antimicrobial and antioxidant capacities [2,3]. Therefore, the repurpose of citrus by-products, particularly the essential oils extracted from their peels, presents a favorable solution for environmental challenges posed by excessive waste, bringing forward a valuable approach for innovative applications regarding the food industry, among other sectors. Objectives: The present work aimed the extraction and characterization of essential oils, from orange (Citrus sinensis) and lemon (Citrus limon) peels, using a sustainable approach based on green chemistry principles, in a way to valorize these bioactive compounds through potential food preservation applications, promoting circular economy within the industry.
- Amputação abomino-perineal: uso de terapia de pressão negativa na ferida perinealPublication . Miranda, Liliana; Carvalho, Ângela; Costa, Sandra; Martins, Mónica; Amado, João; Alves, PauloA Amputação Abdomino-Perineal (AAP) é a técnica mais eficaz no tratamento da neoplasia do reto baixo e do tumor do canal anal. Sendo uma cirurgia de grande excisão tecidular, associada a grande parte das vezes a radioterapia (RT) prévia à cirurgia, compromete a cicatrização da ferida perineal, que se traduz numa elevada taxa de complicações no pós-operatório imediato (entre 14% a 60%), nomeadamente infeção da ferida operatória e consequente deiscência. A Terapia de Pressão Negativa (TPN) tem surgido como uma opção no tratamento de complicações da ferida cirúrgica, bem como na prevenção das mesmas.
