Production of sustainable aviation fuel precursors using the oleaginous yeast R...
Saraiva Lopes da Silva, Maria Teresa; Dutra, Francisca; Gomes, Miguel; Costa, Paula; Paradela, Filipe; Ferreira, Frederico CasteloABSTRACT: Sustainable aviation fuels (SAF) obtained from renewable sources of carbon can reduce carbon dioxide emissions and contribute for mitigating climate changes. In the present study, the yeast Rhodotorula toruloides PYCC 5615 was found to be highly promising for the bioconversion of eucalyptus bark hydrolysate and the accumulation of intracellular lipids which were further thermochemically processed to b...
Monitoring Yeast Cultures Grown on Corn Stover Hydrolysate for Lipid Production
Fontes, Afonso; Francisco, Ricardo; Ferreira, Frederico Castelo; Faria, Nuno Torres; Marques, Susana; Reis, Alberto; Moura, Patrícia; Lukasik, Rafal M.ABSTRACT: Microbial oils can be used as an alternative sustainable and renewable feedstock to fossil reserves for producing lubricants and polyurethane materials. Two oleaginous yeasts were grown on non-detoxified corn stover hydrolysate supplemented with corn steep liquor and mineral medium in shake flasks. Trichosporon oleaginosus DSM 11815 displayed the highest lipid production. This strain was further culti...
Integrated perspective on microbe-based production of itaconic acid: from metab...
Nascimento, Miguel Figueiredo; Marques, Nuno; Correia, Joana; Faria, Nuno Torres; Mira, Nuno P.; Ferreira, Frederico CasteloABSTRACT: The discovery of itaconic acid as a product of citric acid pyrolytic distillation in 1837 opened the possibility of using it as a polymer building block. Itaconic acid, featuring two carboxylic acids and an unsaturated group, can potentially be used as a building block in several chemical syntheses, with a particular emphasis on polymer manufacture. The elucidation of biochemical pathways originating ...
Production of Mannosylerythritol Lipids Using Oils from Oleaginous Microalgae: ...
Nascimento, Miguel Figueiredo; Coelho, Tiago; Reis, Alberto; Gouveia, Luisa; Faria, Nuno Torres; Ferreira, Frederico CasteloABSTRACT: Mannosylerythritol lipids (MELs) are biosurfactants with excellent biochemical properties and a wide range of potential applications. However, most of the studies focusing on MELs high titre production have been relying in the use of vegetable oils with impact on the sustainability and process economy. Herein, we report for the first time MELs production using oils produced from microalgae. The bio-oi...

Moesziomyces spp. cultivation using cheese whey: new yeast extract-free media, ...
Nascimento, Miguel Figueiredo; Barreiros, Ricardo; Oliveira, Ana Cristina; Ferreira, Frederico Castelo; Faria, Nuno TorresABSTRACT: Mannosylerythritol lipids (MELs) are biosurfactants with excellent biochemical properties and a wide range of potential applications. However, high production costs, low productivity and unsatisfactory scale-up production have hampered commercial adoption. Herein, we report for the first time the beta-galactosidase production by Moesziomyces spp. from different sugars (D-galactose, D-glucose and D-lac...
Additive manufactured Poly("-caprolactone)-graphene scaffolds: Lamellar crystal...
Biscaia, Sara; Silva, João C.; Moura, Carla; Viana, Tânia; Tojeira, Ana; Mitchell, Geoffrey R.; Pascoal-Faria, Paula; Ferreira, Frederico CasteloUnderstanding the mechano–biological coupling mechanisms of biomaterials for tissue engineering is of major importance to assure proper scaffold performance in situ. Therefore, it is of paramount importance to establish correlations between biomaterials, their processing conditions, and their mechanical behaviour, as well as their biological performance. With this work, it was possible to infer a correlation be...

PEDOT:PSS-coated polybenzimidazole electroconductive nanofibers for biomedical ...
Sordini, Laura; Silva, João C.; Garrudo, Fábio F. F.; Rodrigues, Carlos A. V.; Marques, Ana C.; Linhardt, Robert J.; Cabral, Joaquim S. M.Bioelectricity drives several processes in the human body. The development of new materials that can deliver electrical stimuli is gaining increasing attention in the field of tissue engineering. In this work, novel, highly electrically conductive nanofibers made of poly [2,20 - m-(phenylene)-5,50 -bibenzimidazole] (PBI) have been manufactured by electrospinning and then coated with cross-linked poly (3,4-ethyl...
