Diversity and Distribution of Carotenogenic Algae in Europe: A Review

Konstantin Chekanov

Summary: This article reviews the existing data on microalgal species known as potential carotenoid producers in biotechnology. It includes well-known species like Haematococcus and Dunaliella, as well as lesser-known representatives. Their distribution covers Europe from the Greek Mediterranean coast in the south to snow valleys in Norway in the north, and from ponds in Portugal to saline lakes and mountains in Ukraine. A wide range of algal secondary carotenoids are reviewed, including beta-carotene, astaxanthin, canthaxanthin, echinenone, adonixanthin, and adonirubin. The main concepts of carotenoid-producing algae biology are briefly explained for convenience.

Carotenogenic Activity of Two Hypersaline Greek Dunaliella salina Strains under Nitrogen Deprivation and Salinity Stress

Xanthi Chantzistrountsiou et al.

Summary: This study investigates the culture growth and carotenogenic activity of two Greek Dunaliella salina strains under stress conditions, focusing on beta-carotene production as well as lutein and zeaxanthin. The strains are cultivated in different salt and nitrogen conditions. It is found that all three strains produce more beta-carotene under nitrogen deprivation conditions, with the AthU-Al D31 strain also showing high carotenoid production under salt stress. The HPLC carotenoid profiles reveal reduced lutein production and increased beta-carotene production in nitrogen deprivation conditions.

Isolation, identification, and chemical composition analysis of nine microalgal and cyanobacterial species isolated in lagoons of Western Greece

George Hotos et al.

Summary: In this study, nine halotolerant microorganisms were collected from lagoons in Western Greece, identified by morphological observations and DNA sequencing data. These microorganisms, including Chlorophyta, cyanobacteria, and dinoflagellate, showed potential for future exploitation, with high protein content and sufficient fatty acid accumulation. The pigments composition analysis indicated the dominance of chlorophyll b in some species and a high content of carotenoids in Amphidinium carterae. This study opens up opportunities for the valorization and recovery of valuable compounds from these newly discovered species.

Comparative morphological, physiological, biochemical and genomic studies reveal novel genes of Dunaliella bioculata and D. quartolecta in response to salt stress

Fan Gao et al.

Summary: The study compared the characteristics of D. bioculata and D. quartolecta at different levels and found that D. quartolecta is more halophilic than D. bioculata, with more effective responses to high salt stress. Genomic lengths, gene predictions, and novel genes were analyzed, showing different patterns between the two algae species. Additionally, differential expression of specific genes in response to salinity was observed.

Enhanced β-carotene production in Dunaliella salina under relative high flashing light

Yimei Xi et al.

Summary: This study investigated the effect of flashing light on biomass accumulation, beta-carotene content, and photosynthetic response in the green microalga Dunaliella salina. The results showed that flashing light led to higher biomass and beta-carotene productivity compared to continuous light. The study also found a positive correlation between the enhanced beta-carotene yield induced by flashing light and the increase in electron transport rate and reactive oxygen species content in Dunaliella salina.

Molecular and phylogenetic analysis reveals new diversity of Dunaliella salina from hypersaline environments

Andrea Highfield et al.

Summary: This study isolated twelve hyper-beta carotene-producing strains of algae belonging to the genus Dunaliella salina from various hypersaline environments. Phylogenetic analysis revealed the need for clarification on the taxonomy of Dunaliella salina, leading to the proposal of dividing D. salina into four sub-clades based on a robust phylogeny. The study demonstrates the considerable genetic diversity within D. salina and highlights the potential of genetic analyses in selecting economically important strains.

ROS Induce β-Carotene Biosynthesis Caused by Changes of Photosynthesis Efficiency and Energy Metabolism in Dunaliella salina Under Stress Conditions

Yimei Xi et al.

Summary: This study investigated the regulatory mechanism of beta-carotene accumulation in Dunaliella salina under stress conditions, revealing a positive correlation between cellular ROS level and beta-carotene content, and a negative correlation between F-v/F-m of PSII and beta-carotene content. Transcriptional analysis showed that ROS induce beta-carotene accumulation by modulating genes involved in photosynthesis and beta-carotene biosynthesis.

Disparity of the carotenoids antioxidant properties of wild-type and D-PSY-transgenic Dunaliella parva strains under three environmental stresses

Mostafa M. S. Ismaiel et al.

Summary: The transgenic algal strain D-PSY with exogenous phytoene synthase gene showed higher carotenoid content and superior antioxidant properties compared to the wild type; applied stressors stimulated carotenoid content and antioxidant activities of the algae; biochar and nitrogen treatments generally enhanced the antioxidant activities of carotenoids, while cobalt was less effective in this regard.

The Effect of Various Salinities and Light Intensities on the Growth Performance of Five Locally Isolated Microalgae [Amphidinium carterae, Nephroselmis sp., Tetraselmis sp. (var. red pappas), Asteromonas gracilis and Dunaliella sp.] in Laboratory Batch Cultures

George N. Hotos et al.

Summary: After a 1.5-year screening survey in the lagoons of Western Greece, five species of microalgae (Amphidinium carterae, Nephroselmis sp., Tetraselmis sp., Asteromonas gracilis, and Dunaliella sp.) were found to be able to grow adequately in different salinity conditions in laboratory settings, with the best growth observed under high illumination conditions (8000 lux). Each species exhibited different responses to the salinity levels, leading to variations in growth efficiency and productivity.
