Use of <em>Dunaliella salina</em> in Environmental Applications <sup>†</sup>

Abstract

A macro and microalgae are widely used in environmental and biotechnological applications due to their unique natural properties. Algae groups are aquatic organisms that can be found in many parts of the world and vary in size from 3-10 μ to 70 cm. Algae are divided into two as prokaryotic (microalgae) and eukaryotic (macroalgae) according to their biological formations. "Cyanophyta" as microalgae and "Phaeophyta, Rhodophyta, Chlorophyta, Flagelleta" as macro algae are known. Dunaliella salina is a living thing that can live in saltwater ecosystems and belong to the microgreen algae group. Since these algae are a natural source of beta-carotene, they are of particular importance in the cosmetics and food industries compared to other green microalgae species. Almost all algae groups are used for different purposes in a wide variety of sectors. Dunaliella spp. types are used extensively in areas such as the energy sector (bio fuel), cosmetics, medical applications, bioplastic production, wastewater treatment, food industry. In addition, the most basic effect parameter of pink color formation in lakes with salt content due to seasonal changes is D. salina, which is not an environmental problem. Increasing environmental pollution, unconscious energy consumption, and climate change have led countries to seek alternative solutions to environmental issues and to develop environmentally friendly-technological methods. For sustainable environmental management and minimization of pollution; The benefits of using algae species have been demonstrated by different applications. In the literature, D. salina has focused on algae production and the use of pigments in the cosmetics and food industry. The aim of this study is to investigate the recent researches on D. salina and reveal the importance of this algae, especially in terms of sustainable environment and energy.

Marine-derived protein: peptide bioresources for the development of nutraceuticals for improved athletic performance

“…Furthermore, bioactive peptides from marine microorganisms are starting to be applied as part of athlete's diet ( 16 ). Bioactive peptides were found to have a positive effect on body composition, namely increasing lean body mass and decreasing fat mass ( 17 ).…”

Algae Based Solutions for Polluted Environments to Restore Ecosphere Equilibrium

“…For example D. Salina a high light and low temperature tolerant specie form important phytoplankton communities in hypersaline and marshy environments. Another specie called D. acidophila flourish in environments with pH as low as 0-1 [26].…”

Cross-kingdom metagenomic profiling of Lake Hillier reveals pigment-rich polyextremophiles and wide-ranging metabolic adaptations

“…Previous studies in other saline environments have hypothesized similar lake pigments to derive from the algae Dunaliella salina (16). D. salina is a unicellular microalgae species known for its ability to thrive in high saline conditions and for its production of the carotenoid pigment β-carotene.…”
