Impact of fermentation on the antioxidant activity and color of haematococcus p...
Bassani, Joseane C.; Martins, Valter; Barbosa, Joana; Steffens, Juliana; Backes, Geciane T.; Pereira, Hugo; Pintado, Manuela E.; Morais, Alcina M. M. B.Microalgae are emerging as a promising ingredient for the food industry due to their sustainable cultivation and production of a variety of bioactive compounds, including proteins, lipids, carbohydrates, antioxidant compounds, and pigments [1]. Among the many cataloged species of microalgae, two stand out in research due to their powerful applications in the pharmaceutical, nutraceutical, cosmetic, and food and...

Bassani, Joseane C.; Martins, Valter F. R.; Barbosa, Joana; Coelho, Marta; Sousa, Clara; Steffens, Juliana; Backes, Geciane T.; Pereira, HugoHaematococcus pluvialis and Porphyridium cruentum are red microalgae with high biotechnological potential due to their rich composition of bioactive compounds. However, their intense flavor limits their application in food products. This study evaluated the impact of fermentation with Lactiplantibacillus plantarum (30 ?C for 48 h; LAB-to-biomass ratio of 0.1:1; 106 CFU/mL) on the physicochemical and functional ...
Influence of different processing techniques on microalgal protein extraction
Moreira, Catarina; Santos, Pedro Miguel Ferreira; Nunes, R.; Carvalho, Bernardo; Pereira, Hugo; Teixeira, J. A.; Rocha, Cristina M. R.The nutrient-rich composition of microalgae biomass positions it as a highly promising natural food ingredient. This holds the potential to not only enhance the nutritional value of various food products but also simultaneously alter their structural attributes. This work investigated the effect of five protein extraction techniques such as freeze-thawing, enzymatic-assisted extraction, high-pressure homogeniza...
Immunomodulatory inhibition of osteoclastogenesis by a marine microalgal ethano...
Carletti, Alessio; Pes, Katia; Tarasco, Marco; Rosa, Joana; Poudel, Sunil; Pereira, Hugo; Louro, Bruno; Cancela, M. Leonor; Laizé, VincentBackground: Targeting immune pathways to prevent bone loss represents a promising, yet underexplored therapeutic strategy. Methods: An ethanol-soluble fraction derived from the freeze-dried biomass of the marine microalga Skeletonema costatum (SKLT) was tested for its ability to modulate immune responses and inhibit osteoclastogenesis. Its effects were evaluated in a zebrafish model of bone regeneration, a meda...
Enhancing growth, nutrient uptake and flowering of Tagetes patula plants throug...
Vieira, João; Saque, Moisés; Viana, Catarina; Rodrigues, Maria Helena; Guerreiro David Coelho, Luísa Isabel; Gama, Florinda; Varela, João; Pereira, HugoTagetes patula L. is a prominent plant that is frequently used for its ornamental value. Marigolds are sources of various compounds of great interest to agricultural, pharmaceutical, and nutritional industries. Microalgae can be applied as a biostimulant as they have multifunctional properties in agriculture, namely facilitating nutrient uptake, improving crop performance and physiological status, and thus incr...
Impact of seasons on industrial cultivation of Limnospira platensis (Spirulina)...
Guerra, Inês; Torres, Cátia; Cardoso, Helena; Pereira, Hugo; Trovão, Mafalda; Rodrigues, Alexandre M. C.; Varela, JoãoSpirulina is the most commercially produced biomass, among microalgae and cyanobacteria, with extensive applications across food, feed, nutraceutical and biotechnological sectors. While Spirulina cultivation is wellcharacterized at laboratorial and small-scale production, critical knowledge gaps remain regarding industrialscale production in temperate climates. Specifically, there is a lack of robust empirical ...
Heterotrophic cultivation of Chlorella vulgaris yellow mutant on sidestreams: M...
Trovão, Mafalda; Barros, Ana; Machado, Adriana; Reis, Ana; Pedroso, Humberto; Espírito Santo, Gonçalo; Correia, Nádia; Costa, Monya; Ferreira, SaraMicroalgal protein is a promising feedstock to complement and/or replace other protein sources. Besides requiring less land and water usage, microalgae production is a more sustainable process, especially if industrial sidestreams are used as nutrient sources. Additionally, the heterotrophic cultivation of microalgae, such as Chlorella vulgaris, enables the achievement of much higher biomass productivity and lo...

Comparison of different microalgae biomass typologies used in rotifers enrichme...
de Castro, Daniela; Castaldi, Matthew; Martins, Gil; Santos, Tamara; Pereira, Hugo; Diogo, Patrícia; Varela, João; Gavaia, PauloThe use of enriched rotifers with industrially produced microalgae represents a valuable tool for the enhancement of zebrafishlarval nutrition and increased biological performance. Currently, a monoculture of microalgal species (Nannochloropsis sp.) inform of liquid paste is routinely used for rotifers enrichment for zebrafish larvae feeding; however, the most adequate typology (i.e.,paste or freeze-dried) of the...
