Análise Bibliométrica das Publicações do CEOS.PP
Mota, Rita; Nogueira, Daniela; Lopes, Cristina; Azevedo, AnaWith the technological revolution that began in the XX century, there was the need to use metrics that would be helpful to assess the work researchers produced. Hence, bibliometrics emerged as a quantitative and statistical method that, aside from evaluating the quality of the scientific production, according to certain indicators, it also provides insight into the incidence of the different subject areas, bein...
Pilot scale production of Crocosphaera chwakensis CCY0110 and evaluation of its...
Matinha-Cardoso, Jorge; Santos, Tamara; Pereira, Hugo; Varela, João; Tamagnini, Paula; Mota, RitaIn recent years, the large-scale cultivation and commercialization of microalgae/cyanobacteria biomasses have become a worldwide trend, mainly directed to the animal and human nutrition markets due to their outstanding nutritional value. However, only a very limited number are currently classified as food ingredients by Food Safety regulators worldwide. Crocosphaera chwakensis CCY0110 is a marine unicellular cy...
Assessing the antitumor potential of variants of the extracellular carbohydrate...
Mota, Rita; Lima, Raquel T.; Flores, Carlos; Silva, Juliana F.; Cruz, Beatriz; Alves, Bárbara; Pinto, Marta T.; Adessi, Alessandra; Pereira, Sara B.Cancer is a leading cause of death worldwide with a huge societal and economic impact. Clinically effective and less expensive anticancer agents derived from natural sources can help to overcome limitations and negative side effects of chemotherapy and radiotherapy. Previously, we showed that the extracellular carbohydrate polymer of a Synechocystis ΔsigF overproducing mutant displayed a strong antitumor activi...
A new cyanobacterial species with a protective effect on lettuce grown under sa...
Brito, Ângela; Rocha, Mariana; Kaštovský, Jan; Vieira, Jorge; Vieira, Cristina P.; Ramos, Vitor; Correia, Manuel; Santos, Marina; Mota, RitaIn this work, a new terrestrial cyanobacterial species, Oculatella lusitanica LEGE 161147, was isolated and characterized using a polyphasic approach. Morphologically, O. lusitanica shares characteristics with different Oculatella species (mainly with O. crustae-formantes), lacking distinctive features. However, the phylogeny based on the 16S rRNA gene sequence and the 16S-23S ITS secondary structures support t...
Peaky Blinders. Multimodal Narratives of Intercultural Communication
Mota, RitaEste trabalho surge no âmbito da unidade curricular de Comunicação Intercultural, e por isso mesmo é um trabalho de pesquisa, análise e conceção de conceitos lecionados em teoria, que têm repercussão direta na prática. Neste sentido, o desafio desde o início passou por escolher algum tipo de formato onde fosse possível aplicar estes conceitos, de uma forma crítica e opinativa, de modo a tornar o trabalho muito ...
Cyanoflan: a cyanobacterial sulfated carbohydrate polymer with emulsifying prop...
Mota, Rita; Vidal, Ricardo; Pandeirada, Carolina; Flores, Carlos; Adessi, Alessandra; De Philippis, Roberto; Nunes, Cláudia; Coimbra, Manuel A.The extracellular polysaccharides produced by cyanobacteria have distinctive characteristics that make them promising for applications ranging from bioremediation to biomedicine. In this study, a sulfated polysaccharide produced by a marine cyanobacterial strain and named cyanoflan was characterized in terms of morphology, chemical composition, and rheological and emulsifying properties. Cyanoflan has a 71 % ca...
Thin-layer nanofiltration membranes using engineered biopolymers for seawater d...
Büttel, Zsófia; Guimarães, Rodrigo; Santos, Carla; Silva, Carla J. S. M.; Pereira, Sara B.; Mota, Rita; Tamagnini, Paula; Zille, AndreaNowadays water demand already exceeds supply and water scarcity is a global problem. So it is necessary to develop novel technologies to be able to use poorer quality source waters for drinking water production. Once considered as an expensive, ultimate solution for water supply, desalination is becoming affordable. The two most commonly used seawater desalination methods are Multi-stage Flash Distillation (MSF...
Production and characterization of extracellular carbohydrate polymer from Cyan...
Mota, Rita; Guimarães, Rodrigo; Büttel, Zsófia; Rossi, Federico; Colica, Giovanni; Silva, Carla J. S. M.; Santos, Carla; Gales, Luís; Zille, AndreaCyanobacterial extracellular polymeric substances (EPS) are heteropolysaccharides that possess characteristics suitable for industrial applications, notably a high number of different monomers, strong anionic nature and high hydrophobicity. However, systematic studies that unveil the conditions influencing EPS synthesis and/or its characteristics are mandatory. In this work, Cyanothece sp. CCY 0110 was used as ...
Culture-dependent characterization of cyanobacterial diversity in the intertida...
Brito, Ângela; Ramos, Vitor; Seabra, Rui; Santos, Arlete; Santos, Catarina; Lopo, Miguel; Ferreira, Sérgio; Martins, António; Mota, RitaCyanobacteria are important primary producers, and many are able to fix atmospheric nitrogen playing a key role in the marine environment. However, not much is known about the diversity of cyanobacteria in Portuguese marine waters. This paper describes the diversity of 60 strains isolated from benthic habitats in 9 sites (intertidal zones) on the Portuguese South and West coasts. The strains were characterized ...
