Carotenoid content of microalga, Dunaliella salina was increased using different stress parameters, such as cell division inhibition (vinblastine), nitrogen starvation, high salinity and high irradiation with high temperature. Vinblastine had very little favourable effect. Salinity above 3 M significantly decreased the cell growth rate due to cell death but increased the per cell carotenoid con...

The green algae Dunaliella salina offers great potential for the food industry due to its high ?-carotene content. To guarantee economic profitability of cultivation, growth conditions must be improved. Therefore, effects pH and salinity on cultivation alga D. were investigated optimized. simplex method was applied find optimum these two parameters maximize biomass cell number salina. found at ...

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...

A new method to measure intracellular volume in Dunaliella was developed, where lithium ions are used as monitors of the extracellular volume. Li(+) is shown to be impenetrable to the intracellular volume, insignificantly absorbed to the algae, and is rapidly and evenly distributed within the extracellular volume. The method is suggested to be free of several limitations and consistent errors p...
