“…Moreover, P. tricornutum have shown functional properties comparable to those of soybean flour (Guil-Guerrero et al 2004). Campa-Córdova et al (2002) examined the effect of b-glucan and sulphated polysaccharide P. tricornutum solutions on white shrimp (Litopenaeus vannamei) superoxide anion generation and superoxide dismutase activity.…”

The present study assessed the effects of three orally administered microalgae (Nannochloropsis gaditana, Tetraselmis chuii and Phaeodactylum tricornutum) on different immune parameters and immune-related gene expression of gilthead seabream (Sparus aurata L.). Fish were fed a control or one of six experimental diets and sampled at 2 and 4 weeks of treatment. At the end of the trial, growth performance and different systemic and local immune activities were measured (natural haemolytic complement activity, IgM levels, phagocytosis and respiratory burst). The expression levels of different immune-associated genes (EF-1α, IgM(H), TCR-β, MHCIα, MHCIIα, CSF-1R and β-defensin) were analysed in head-kidney and gut. Administration of N. gaditana and T. chuii resulted in a significant increase in haemolytic complement activity, phagocytic capacity, as well expression level of β-defensin, as well as MHCIIα and CSF-1R, respectively. The P. tricornutum-supplemented diet provoked immunostimulation, and very little effect on gene expression was observed. These results suggest that dietary microalgae enhance gilthead seabream defence activity, which could be very important in order to consider such microalgae as a possible additive in fish diets.

“…As maiores solubilidades protéicas foram obtidas na faixa de pH alcalino, independente da condição de secagem. A máxima solubilidade obtida foi de 48,6% em pH 10,0, valor semelhante aos reportados por outros autores que obtiveram 50% de solubilidade protéica nesta mesma faixa de pH, para outras espécies de microalgas [3, 9,11,25].…”

“…No entanto, no presente trabalho, a biomassa liofilizada apresentou menor solubilidade que a obtida por desidratação em secador de bandejas, nas diferentes condições de pH avaliadas. GUIL-GUERRERO et al [11] observaram para dois tipos de microalgas liofilizadas, solubilidade de cerca de 60 e 35% (P. tricornutum e P. cruentus, respectivamente) em pH 10,0 e inferior a 10% em pH 4,0 .…”

RESUMOO objetivo do presente trabalho foi avaliar a fração protéica da cianobactéria Aphanothece microscopica Nägeli cultivada no efluente da parboilização do arroz quando submetida a diferentes condições de secagem. A produção da biomassa foi realizada a partir da água residuária do processo de parboilização do arroz em bioreatores de coluna de bolhas. A biomassa foi separada do efluente por centrifugação e desidratada em secador descontínuo de bandejas nas condições de 40, 50 e 60ºC e espessuras de bandejas de 5 e 7 mm. O comportamento eletroforético das proteínas da biomassa foi analisado por eletroforese em gel de poliacrilamamida na presença de dodecil sulfato de sódio (SDS-PAGE) e apresentou bandas com peso molecular de 15 kDa a 62,5 kDa. O perfil aminoacídico mostrou teores superiores aos recomendados pelo padrão FAO, com exceção dos aminoácidos lisina e dos sulfurados (MET+CYS). A caracterização funcional, expressa em termos de solubilidade e capacidade emulsificante, demonstrou a influência da condição de secagem na funcionalidade protéica da biomassa.

SUMMARYPROTEIN CHARACTERISATION OF THE Aphanothece microscopica Nägeli CYANOBACTERIUM CULTIVATED IN PARBOILED RICE EFFLUENT. The objective of the present work was to evaluate the protein fraction of Aphanothece microscopica Nägeli cyanobacteria cultivated in the parboiled rice effluent, submitted to different drying conditions. The production of the biomass was done by using wastewater from the process of rice parboiling in a bubble column bioreactor. The biomass was separated from the effluent by centrifugation and dehydrated in a tray dryer at 40, 50 and 60 o C and thicknesses of 5 and 7 mm. The eletroforetic profile of proteins of the biomass was analysed by SDS-PAGE and presented bands with molecular weight between 62.5-15kDa. The amino acid profile was higher than the concentrations recommended by standard FAO, with the exception of the amino acids (LYS) and the sulphurated (MET+CYS). The functional properties characterisation in terms of protein solubility and emulsification capacity demonstrated the influence of the drying condition in the protein functionality of the biomass.

“…The high protein content of microalgae is the major reason for the untraditional source of protein [1]. Moreover, the amino acids of microalgae which could synthesize essential amino acid to humans and animals compares favorably with that of other food proteins [2]. Furthermore, there are many valuable antioxidants in microalgae, e.g., chlorophyll, carotenoids, astaxanthin, lutein and phycobiliproteins [3,4].…”
