In situ monitoring of chlorophyll a fluorescence in Nannochloropsis oceanica cu...
Carneiro, Mariana; Chini Zittelli, Graziella; Cicchi, Bernardo; Touloupakis, Eleftherios; Faraloni, Cecilia; Maia, Inês Beatriz; Pereira, HugoIn situ chlorophyll a fluorescence measurements were applied to monitor changes in the photochemical variables of Nannochloropsis oceanica cultures under nitrogen-deplete and nitrogen-replete (control) conditions. In addition, growth, lipid, fatty acid, and pigment contents were also followed. In the control culture, growth was promoted along with pigment content, electron transport rate (ETR), and polyunsatura...
Isolation, Identification and Biotechnological Applications of a Novel, Robust,...
Correia, Nádia; Pereira, Hugo; Silva, Joana T.; Santos, Tamára; Soares, Maria; Sousa, Carolina B.; Schüler, Lisa M.; Costa, Margarida; Varela, JoãoBioprospection of novel autochthonous strains is key to the successful industrial-scale production of microalgal biomass. A novel Chlorococcum strain was recently isolated from a pond inside the industrial production facility of Allmicroalgae (Leiria, Portugal). Phylogenetic analysis based on 18S ribosomal ribonucleic acid (rRNA) gene sequences suggests that this isolate is a novel, free-living Oophila amblysto...
Incorporation of defatted microalgal biomass (Tetraselmis sp. CTP4) at the expe...
Pereira, Hugo; Sardinha, Manuel; Santos, Tamára; Gouveia, Luisa; Barreira, Luísa; Dias, Jorge; Varela, JoãoABSTRACT: The forecasted growth of the aquaculture sector requires the use of novel and sustainable ingredients in aquaculture feeds. A study was undertaken to evaluate the effect of a 10% incorporation of defatted microalgal biomass (DMB) of Tetraselmis sp. CTP4, used at the expense of dehulled solvent-extracted soybean meal (SBM), on the growth performance, nutrient digestibility and physiological response to...
Development of an organic culture medium for autotrophic production of Chlorell...
Machado, Adriana; Pereira, Hugo; Costa, Margarida; Santos, Tamára; Carvalho, Bernardo; Soares, Maria; Quelhas, Pedro; Silva, Joana T.; Trovão, MafaldaMicroalgal biomass has gained increasing attention in the last decade for various biotechnological applications, including human nutrition. Certified organic products are currently a growing niche market in which the food industry has shown great interest. In this context, this work aimed at developing a certified organic culture medium for the production of autotrophic Chlorella vulgaris biomass. A preliminary...
Coccolithophores as potential marine resource for sustainable aquaculture
Vicente, Bernardo; Santos, Tamára; São João, Ricardo; Rodrigues, Luísa; Pereira, Hugo; Varela, João; Tenreiro, AnaCoccolithus braarudii (holococcolith) and Emiliana huxleyi (heterococcolith) were isolated from Portuguese coastal waters and domesticated under laboratory conditions with the objective of providing strains with high potential for the production of high value products for aquaculture and biotechnology. The growth patterns and photophysiology of the two species were investigated under controlled conditions, (19±...
Scale-up and large-scale production of Tetraselmis sp CTP4 (Chlorophyta) for CO...
Pereira, Hugo; Páramo, Jaime; Silva, Joana; Marques, Ana; Barros, Ana; Maurício, Dinis; Santos, Tamára; Schulze, Peter; Barros, Raúl; Gouveia, LuisaABSTRACT: Industrial production of novel microalgal isolates is key to improving the current portfolio of available strains that are able to grow in large-scale production systems for different biotechnological applications, including carbon mitigation. In this context, Tetraselmis sp. CTP4 was successfully scaled up from an agar plate to 35-and 100-m(3) industrial scale tubular photobioreactors (PBR). Growth w...
