“…Though most research is realized through photoautotrophic and heterotrophic cultivation modes, there are algae that can grow under mixotrophic [33] and photoheterotrophic modes [34]. On autotrophic cultivation, microalgae generate organic compounds by using sunlight to process an inorganic carbon source, mainly CO 2 [35].…”

Microalgae are aquatic unicellular microorganisms that can be found both in freshwater and marine systems; are capable of photosynthesis; and can grow as individual cells or associated in chains or small colonies. Microalgae cultivation has gained large momentum among researchers in the past decades due to their ability to produce value metabolites, remarkable photosynthetic efficiency, and versatile nature. The wide technological potential, and thus increasing amount of scattered knowledge, may become the very first barrier that a post graduating student, or any non-specialist reader, will face when introduced to the subject. In this review paper, we access the core aspects of microalgae technology, covering their main characteristics, and comprehensively presenting the main features of their various cultivation modes and biological activity from metabolites.

“…These microorganisms are the predominant algae in saltworks and naturally occurring hypersaline environments and are known by their ability to adapt to various changes in medium. Dunaliella species were widely distributed in the world and live in an extremely wide range of habitats [7]. These microrganisms were cultivated in many countries to produce carotenoids [8,9], glycerol [8], proteins and vitamins [10], feeding for fish and human consumption [11,12], biofuel production [13,14] and pharmaceutical formulations [15].…”

Abstract:In order to determine the impact of nitrogen deficiency in medium, growth rate and carotenoids contents were followed during 15 days in two strain Dunaliella spp. (DUN2 and DUN3), isolated respectively from Azla and Idao Iaaza saltworks in the Essaouira region (Morocco). These microalgae were incubated at 25 ± 1 °C with a salinity of 35‰ and continuous light in four growth media with different concentrations of sodium nitrate (NaNO 3 ): 18.75 g/L, 2.5 g/L, 37.5 g/L and 75 g/L. Maximum of cell density was observed under high sodium nitrate concentration during logarithmic phase of growth. The highest specific growth rate was 0.450 × 10 6 ± 0.006 cells/mL and 2.680 × 10 6 ± 0.216 cells/mL, respectively for DUN2 and DUN3. Carotenoids production mean were not stimulated under nitrogen deficiency, and the highest content was showed in DUN2 at high nitrogen concentration (3.210 ± 0.261 μg·mL -1 ) compared with DUN3 strain.
