New Insights on Gordonia alkanivorans Strain 1B Surface-Active Biomolecules: Go...
Tavares, João; Paixão, Susana M.; Silva, Tiago; Alves, LuísABSTRACT: Biosurfactants/bioemulsifiers (BSs/BEs) can be defined as surface-active biomolecules produced by microorganisms with a broad range of applications. In recent years, due to their unique properties like biodegradability, specificity, low toxicity, and relative ease of preparation, these biomolecules have attracted wide interest as an eco-friendly alternative for several industrial sectors, escalating g...
Psychometric validation of the Portuguese ALONE scale and analysis of factors a...
Tavares, João; Silva, Sofia; Ribeiro, Ana; Matheus, Anna; Sá-Couto, Pedro; Sousa, Liliana; Guerra, SaraSevere loneliness poses a significant risk to older adults' health and quality of life. This study assessed the psychometric properties (reliability and validity) of the Portuguese version of the ALONE scale in community-dwelling older adults and explored the scale's associations with sociodemographic, social isolation, depression, life satisfaction, and daily functioning.

Application of In-House Xylanases as an Addition to a Commercial Cellulase Cock...
Montiel, Carmina; Hernández-Meléndez, Oscar; Marques, Susana; Gírio, Francisco; Tavares, João; Ontañon, Ornella; Campos, Eleonora; Bárzana, EduardoABSTRACT: The study involves the use of commercial cellulase Cellic CTec2 in combination with two inhouse xylanases, PxXyn10A (XynA), a recombinant purified enzyme from Paenibacillus xylanivorans A59, and a xylanase enzymatic extract from native Moesziomyces aphidis PYCC 5535T (MaPYCC 5535T), for the enzymatic hydrolysis of pretreated blue agave bagasse (BAB) at the high solids load of 20% (w/v). Three differen...
Streamlining the biodesulfurization process: development of an integrated conti...
Silva, Tiago; Paixão, Susana M.; Tavares, João; Paradela, Filipe; Crujeira, Teresa; Roseiro, J. Carlos; Alves, LuísABSTRACT: Biodesulfurization is a biotechnological process that uses microorganisms as biocatalysts to actively remove sulfur from fuels. It has the potential to be cleaner and more efficient than the current industrial process, however several bottlenecks have prevented its implementation. Additionally, most works propose models based on direct cultivation on fuel, or batch production of biocatalysts followed ...

Economic and financial model to the mass‐rearing of Macrolophus pygmaeus (Rambu...
Dutra, Tiago M.; Batista, Maria Da Graça; Teixeira, João; Todorova, Silvia; Oliveira, Luísa; Tavares, João; Borges, Isabel; Soares, António O.ABSTRACT: BACKGROUND - Tuta absoluta (Meyrick) is a major pest of tomato produced in glasshouses and open field, causing severe damages to crops, reducing the quality of tomato fruits. The current maintenance of the pest populations below the economic threshold is not achieved by natural and classical control, thus requiring the continuous application of biological control agents (BCAs), under an augmentative o...
