Microalgae as a selenium vehicle for nutrition: a review

Selenium (Se) is essential for human and animal nutrition, playing a key role in antioxidant and immune functions. Organic Se is better for supplementation because it is more efficiently assimilated and less toxic than its inorganic form. Due to the scarcity of Se in European soils, supplementation in feed and food is necessary. Currently, inorganic Se (sodium selenite and selenate) and organic Se in Se-enriche...

Exploiting potential probiotic lactic acid bacteria isolated from Chlorella vul...

Lactic acid bacteria (LAB) have been documented as potential vitamin B12 producers and may constitute an exogenous source of cobalamin for the microalga Chlorella vulgaris, which has been described as being able to perform vitamin uptake. Hence, there is an interest in discovering novel B12-producing probiotic LAB. Therefore, the purpose of the current work was to perform a phenotype–genotype analysis of the vi...

How does dilution affect the conductivity, the propensity to aggregate and the ...

The current theories do not provide a convincing explanation for many of the protein' manifestations in solution. Therefore, to shed some light on this critical question, the present work analyzed the effect of dilution on the ability of proteins to catalyze chemical reactions, the so-called biological activity. As models enzymes, laccase from Trametes versicolor and chicken egg white lysozyme were used. The re...

Dental abscess and “unexpected death”...

Even though we are living in an era of major technical-scientific advances and effective antimicrobial and antiviral therapy,dental infections are still the most important predisposing factors for head and neck infections. Odontogenic infections can cause severe complications, e.g. compromised airways, tissue necrosis, deep neck infections, mediastinitis, endocarditis and sepsis. These severe odontogenic infect...

Marine cyanobacteria isolated from the portuguese coast as a source of bioactiv...

As cianobactérias marinhas constituem uma fonte promissora de compostos com potencial antitumoral. Nos últimos anos, um arsenal de compostos tem sido revelado, alargando a gama de novos compostos ou estruturas de base ao desenvolvimento de novas drogas. Neste projeto tivemos como objetivo avaliar o potencial de cianobactérias da coleção LEGE-CC como fonte de compostos antitumorais. Foi também nosso objetivo ava...

Effects of outdoor and indoor cultivation on the polar lipid composition and an...

Nannochloropsis is a genus of eicosapentaenoic acid-rich microalgae with high levels of value-added polar lipids. However, the polar lipid composition of microalgal biomass is highly dependent on culture conditions (e.g., light or temperature), which are significantly different under indoor and outdoor culture conditions. In this study, we sought to investigate the plasticity of the polar lipid profile of a mar...
