Abstract The production of metabolites in microalgae is influenced by extreme cultivation conditions. Bicarbonate an inorganic carbon source for phototrophic culturing. In this study, the effect dissolved (DIC) (0.4–13 g L −1 ) on accumulation Dunaliella tertiolecta biomass presented. highest levels primary [lipid (239.6 ± 24.3 mg ), protein (336.2 47.5 )], secondary [total phenolic (12.8 2.0 t...

BACKGROUND For many years, increasing demands for fossil fuels have met with limited supply. As a potential substitute and renewable source of biofuel feedstock, microalgae have received significant attention. However, few of the current algal species produce high lipid yields to be commercially viable. To discover more high yielding strains, next-generation sequencing technology is used to elu...

This study investigated the growth, survival and fatty acid composition of sea urchin Paracentrotus lividus larvae fed four microalgal diets: Cricosphaera elongata, Pleurochrysis carterae, Tetraselmis suecica and Dunaliella tertiolecta (control). Larvae were successfully raised to competence for metamorphosis when fed C. elongata, P. carterae and D. tertiolecta diets but significant differences...

Time-course variation of lipid and carotenoid production under high light (300 μE/m²s) and nitrogen starvation conditions was determined in a Dunaliella tertiolecta strain. Nanoelectrospray (nanoESI) chip based direct infusion was used for lipid analysis and ultra-performance liquid chromatography (UPLC) coupled with a photodiode array (PDA) or atmospheric chemical ionization mass spectrometry ...

Zeaxanthin is a xanthophyll pigment that is regarded as one of the best carotenoids for the prevention and treatment of degenerative diseases. In the worldwide natural products market, consumers prefer pigments that have been produced from biological sources. In this study, a Dunaliella tertiolecta strain that has 10-15% higher cellular zeaxanthin content than the parent strain (zea1), was obta...

Copper toxicity to the freshwater algae Selenastrum capricornutum and Chlorella sp. and the marine algae Phaeodactylum tricornutum and Dunaliella tertiolecta was investigated using different parameters measured by flow cytometry: cell division rate inhibition, chlorophyll a fluorescence, cell size (i.e., light-scattering), and enzyme activity. These parameters were assessed regarding their usef...

This study was conducted under the Italian Ministerial Decree D.M. 173/2016 which regulates assessment of Sediment Class Quality in Italy using ecotoxicological bioassay and chemical analysis (Weight-Of-Evidence model). The aim this work to evaluate real classification obtained by theoretically equivalent responses nine different combinations batteries based on six species: Aliivibrio fischeri ...
