The correlation between water physicochemical parameters and eukaryotic benthic composition was examined in Río Tinto. Principal component analysis showed a high inverse relationship between pH and most of the heavy metals analyzed as well as Dunaliella sp., while Chlamydomonas sp. abundance was positively related. Zn, Cu, and Ni clustered together and showed a strong inverse correlation with t...

I discuss the static quantities of the W boson, magnetic dipole and electric quadrupole moments, in the context of the minimal supersymmetric standard model, in which supersymmetry is broken by soft terms Ao, mo, M1/2. Following a renormalization group analysis it is found that the supesymmetric values of ∆kγ and ∆Qγ can be largely different, in some cases, from the standard model predictions b...

The potential biomass yield per phosphorus and lipid/triglyceride (TAG) accumulation properties of seven microalgal species: Scenedesmus sp. LX1, Chlorella ellipsoidea YJ1, Chlorella vuglaris, Chlorella sorokiniana, Chlorella pyrenoidosa, Dunaliella primolecta and Haematococcus pluvialis were investigated. Among the tested species, Scenedesmus sp. LX1 obtained the smallest minimal phosphorus co...

We have screened for in vitro inhibition of viral replication with extracts from the following marine microalgae: Porphyridium cruentum, Phaeodactylum tricornutum, Tetraselmis suecica, Chlorella autotrophica, Dunaliella tertiolecta, Dunaliella bardawil, Isochrysis galbana, Isochrysis galbana var Tiso, Ellipsoidon sp. and Tetraselmis tetrathele. We have used as viral models two enveloped viruses...

A Halomonas sp., a marine halophilic and oligotrophic bacterium, was grown on exudates of Dunaliella bardawil. The bacteria increased the solubility of Fe, thereby enhancing its availability to the algae. As a result, the algal growth rate increased. Because of these syntrophic relations, growth of the marine alga D. bardawil was facilitated at Fe levels that would otherwise induce Fe deficienc...

Dunaliella salina, halotorelant unicellular green algae, is the main natural source of beta-carotene. Several strains of local Dunaliella salina were isolated. Together with Dunaliella bardawil DCCBC 15 and Dunaliella salina CCAP 19/18, the strains were examined for their growth under the effects of salinities (1 M, 1.5 M and 2 M) and light intensities (50, 100 and 150 μmol photon/m/s). The res...

This study investigated the biochemical suitability of Australian native microalgal species Scenedesmus sp., Nannochloropsis sp., Dunaliella sp., and a chlorophytic polyculture as nutritional supplements for human health. The four microalgal cultures were harvested during exponential growth, lyophilized, and analysed for proximate composition (moisture, ash, lipid, carbohydrates, and protein), ...
