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...
Production and characterization of protein-rich extracts from the red macroalga...
Mateus, Marília; Mão de Ferro, Rita; Pinheiro, Helena M.; Machado, Remígio; R. da Fonseca, M. Manuela; Sapatinha, Maria; Pires, Carla; Marmelo, IsaThe red macroalga Gelidium corneum is a species commercially exploited for agar extraction, though with enormous potential for other industrial applications. This work aimed to produce protein-rich extracts from the crude alga and from residues of the industrial agar extraction process by applying different extraction and recovery procedures, and to characterize the obtained protein extracts. The sequential imp...
Recent reports on domestic wastewater treatment using microalgae cultivation: T...
Vaz, Sofia; Badenes, Sara M.; Pinheiro, Helena M.; Martins, Rui C.The conventional wastewater treatment process (WWTP) is under continuous improvement, mainly to reduce the final pollutant contents in the effluent. The circular economy concept is driving this industry towards the recovery of the carbon (C) and nutrient (nitrogen – N and phosphorus – P) loads as valuable products, also to answer issues related to their depletion in nature. In this context, microalgae cultivati...
Energetic valorization of a heterotrophic microalga residue from biodiesel prod...
Amarelo Santos, Carla Manuela; Pinheiro, Helena M.; Reis, Alberto; Marques, Isabel P.The production of biodiesel from the oil fraction of the heterotrophically grown microalga Chlorella protothecoides generated two waste streams: defatted microalga residues and crude glycerol. These wastes were anaerobically digested separately and in admixture to quantify their energy potential. The defatted microalga residues (from the oil extraction process) were shown to be a suitable substrate for anaerobi...
