The aim of the present work was to evaluate the feasibility of microalgae fonteo using secondary treated domestic wastewater. The aim of this study was to determine the effectiveness micdoalgas biomass growth in laboratory condition. Full Text Available Microalgss the new entries in the food supplements sector, an important place must be assigned to nutraceuticals containing microalgaenowadays accounting for a large and rapidly expanding market.

The transesterification reactions were carried out by using methanol as alcohol and potassium hydroxide as the catalyst. Differential effects of P25 TiO2 nanoparticles on freshwater green microalgae: Lipid and fatty acid composition microalgae Chlorella vulgaris using photobioreactor and open pond.

Increase in concentrations of diesel or its WAF significantly increased toxicity towards growth, measured in terms of miccroalgas a content in both the algae.

Were tested five concentrations of ferric chloride in the suspension containing the microalgae: Otros trabajos iniciales fueron los de Van Donk et al. Based on the results, mathematical models describing the coupled effects of light intensity and DIC concentration on microalgae growth and CO2 biofixation are proposed.

Moreover, the lipid content was significantly positively related to the concentration of hydroxyl functional groups in spite of algal strains or growth phases.

Lipid extracts from C. Varying culture methods of Chlorella vulgaris CV dd been associated with different nutrient composition. These differentially expressed proteins were assigned into nine molecular function categories, including carbohydrate metabolism, lipid biosynthesis, Calvin cycle, cellular respiration, photosynthesis, energy and transport, protein biosynthesis, regulate and defense, and unclassified.

Lutein is a pigment generally extracted from marigold flowers. Peptide data was acquired on an LTQ Orbitrap Velos, raw cknteo were quantitatively analyzed with MaxQuant software and matching with the reference database of Chlorella variabilis and Auxenochlorella protothecoides resulted in the identification of proteins. Additionally, astaxanthin accumulation was enhanced by inhibiting de novo fatty acid biosynthesis.

To investigate the bioaccumulation of Se and miccroalgas effects on the unicellular green alga Chlorella pyrenoidosa, the algal growth curve, fluorescence parameters, antioxidant enzyme activity, and fatty acid and amino acid profiles were examined.

Ecotoxicity of Ag-nanoparticles on two microalgaeChlorella vulgaris and Dunaliella tertiolecta, microalgass in the Archives of Biological Sciences inVol. This study aimed at investigating the potential of microalgae species grown on industrial waste water as a new source of natural antioxidants.

Interestingly, the water treatment preferentially improved the extraction of intracellular fractions, i. The results also showed that the growth potential, lipid production and fatty acid composition of the microalgal strain were dependent on the composition of the flue gas and on the operating strategy deployed.

FS showed high alkali resistance. The models are able to predict the temporal evolution of C. Dry weight biomass is contteo important parameter in algaculture.

The culture of microalgae for lipids accumulation should be performed in certain physicochemical conditions. The capacity of the electron acceptor pool plastoquinone pooland the characteristic times for exchange of PQH 2 Dw with PQ pool and reoxidation of PQH 2 pool were determined.

Minimum inhibitory concentration MIC values of lipid extracts were determined by microdilution method, and the fatty acid methyl esters FAME were analyzed by gas chromatography-mass spectroscopy.

Alginate microbeads as inoculant carriers for plant growth-promoting bacteria. This relies on understanding microalgal lipid metabolism in relation to stress response in particular the deprivation of nutrients that can induce enhanced TAG synthesis.

However, while most membrane lipid classes phosphoglycerolipids and glycolipids were found to decrease, the non-nitrogen containing phosphatidylglycerol levels increased considerably in both algae from initially low levels. Lysine acetylsalicylate increases the safety of a paraquat formulation to freshwater primary producers: For biomass recovery, the correlation for M.

Growth curves of two species were confirmed in the double system bubble column cconteo, and the second growth of yeast was observed during h of mixed culture.

The higher colour removal test score was that with nutrients at 0. This study investigated the effect of nitrogen starvation strategies and photobioreactor design on the performance of lipid production and of CO 2 fixation of an indigenous microalga Chlorella vulgaris ESP An alkali-tolerant Chlorella sp. In relation to the composition of the minerals, the Chlorella cultivated in the most concentrated wastewater, showed higher values when compared with the one cultivated in the others cultures.

Microalgae have recently received a lot of attention as a new biomass source for the production of bio fuels and for the treatment of waste water. On the other hand the amount of palmeotic acid in purified culture of Chaetoceros sp.

The source of laser radiation LR was a helium-neon laser mcroalgas a nominal output power of 1. In both algae the overall fatty acid profiles of the polar lipid classes were largely unaffected by N-deprivation, suggesting a specific FA profile for each compartment is maintained to enable continued function despite considerable reductions in the amount of these lipids.

This lipid quality is suitable for biodiesel production. SEM micrographs of pretreated microalgae present tearing wall agglomerates.
