The photosynthetic and respiratory behaviors of two Dunaliella salina strains (IR-1 and Gh-U) were investigated at two temperature treatments and two assay temperatures. Net photosynthetic rate (P ), photonN saturated net photosynthetic rate (P ), irradiance required to Saturate Photosynthetic (SI), respiration and Nmax pigment changes in D. salina strains, containing different chlorophyll (Chl...

BACKGROUND Culture collapse due to high temperatures can significantly impact the profitability of outdoor algal cultivation systems. The objective of this study was to model for the first time the impact of high temperatures on algal activity and viability. RESULTS Viability measurements on Dunaliella salina cultures were based on cytometry with two fluorescent markers (erythrosine and fluor...

The halotolerant green alga Dunaliella salina (isolate SEA003) recently isolated from salt march at Zaranik nature reserve, North Sinai , (Egypt) was cultivated in the arti ficial seawater medium (ASW) with di fferent sal ini ty levels (0.5, 1, 2, 3, and 4 M), under continuous i llumination of two dif ferent li ght intensities: 50 and 200 μmol m 2s , during 30 day of incubation. The maximum gro...

Microalgal biomass is a promising alternative and renewable substrate for bioenergy production. The main problem its commercial application to obtain keep high level of production by providing microalgae with appropriate conditions growth. aim this study was determine optimal culture such as temperature, photoperiod, pH. amount gravimetry, optical density spectrophotometry, productivity were an...

Microalgae systems have opened up new platforms for molecular farming in closed conditions. Recently, Dunaliella salina has been considered to be a suitable expression host for the production of recombinant proteins due to its significant advantages. It is a unicellular eukaryotic organism lacking cell wall and having post-translational processing for proteins which can grow in high salinity en...

Microalgae, an autotrophic organism has been established as a potential source for biodiesel production. Suitable candidates from marine origin have been selected as viz., Nannochloropsis oculata, Dunaliella salina, and Isochrysis galbana. The microalgae were grown in controlled conditions and an assessment of their growth rate and lipid productivity were made. To analyze the effect of temperat...

Palmella stage is critical for some unicellular algae to survive in extreme environments. The halotolerant algae Dunaliella salina is a good single-cell model for studying plant adaptation to high salinity. To investigate the molecular adaptation mechanism in salinity shock-induced palmella formation, we performed a comprehensive physiological, proteomics and phosphoproteomics study upon palmel...
