Of these species, the green microalga H. pluvialis is recognized as one of the most promising producer of astaxanthin in nature due to its exceptional ability to accumulate large amounts of astaxanthin under stress conditions (Boussiba 2000, Lemoine andSchoefs 2010).…”

Major progress has been made in the past decade towards understanding of the biosynthesis of red carotenoid astaxanthin and its roles in stress response while exploiting microalgae-based astaxanthin as a potent antioxidant for human health and as a coloring agent for aquaculture applications. In this review, astaxanthin-producing green microalgae are briefly summarized with Haematococcus pluvialis and Chlorella zofingiensis recognized to be the most popular astaxanthin-producers. Two distinct pathways for astaxanthin synthesis along with associated cellular, physiological, and biochemical changes are elucidated using H. pluvialis and C. zofingiensis as the model systems. Interactions between astaxanthin biosynthesis and photosynthesis, fatty acid biosynthesis and enzymatic defense systems are described in the context of multiple lines of defense mechanisms working in concert against photooxidative stress. Major pros and cons of mass cultivation of H. pluvialis and C. zofingiensis in phototrophic, heterotrophic, and mixotrophic culture modes are analyzed. Recent progress in genetic engineering of plants and microalgae for astaxanthin production is presented. Future advancement in microalgal astaxanthin research will depend largely on genome sequencing of H. pluvialis and C. zofingiensis and genetic toolbox development. Continuous effort along the heterotrophic-phototrophic culture mode could lead to major expansion of the microalgal astaxanthin industry.

“…Other species, as Scenedesmus, have been found to have rapid growth and resistance to contamination (Lee 2001;Skulberg 2004). They may, therefore, offer an advantage to be used in future studies for carotenoid production (Qin et al 2008).…”

Carotenoid production and change of photosynthetic functions in Scenedesmus sp. exposed to nitrogen limitation and acetate treatment

et al. 2011

Under stress conditions, some microalgae upregulate certain biosynthetic pathways, leading to the accumulation of specific compounds. For example, changing nutrient composition can induce stress in algae's physiological activities, which may trigger an intense increase in carotenoid production. In this study, the change of photosynthetic functions and carotenoid production in the green microalga Scenedesmus sp. was investigated when algal cultures were exposed to conditions including limited nitrogen content with the addition of sodium acetate. Microalgal cultures were treated for 18 days under higher irradiance conditions. We observed a decrease of chlorophyll content induced concomitantly with a decline of photosystem II and I photochemistry. At the same time, an important increase in carotenoid content was detected. By using high-performance liquid chromatographic analysis, we found that the secondary carotenoids astaxanthin and canthaxanthin were accumulated compared to controls. During the process of carotenoid accumulation, chlorophyll degradation was found in addition to a strong decrease in photosynthetic electron transport. Such changes may be associated with the structural reorganization of the photosynthetic apparatus and can be a useful indicator of secondary carotenoid accumulation in algal cultures.

“…Some microalgae play an important role during the life cycle of fish, shrimps, and molluscs during their larval stage. The most commonly used microalgae as animal and fish feed are Chlorella, Arthospira, Tetraselmis, Isochrysis, Pavlova, Phaeodactylum, Chaetoceros, Nannochloropsis, Skeletonema Nutraceuticals, pharmaceuticals, food and feed industries (Guerin et al 2003;Jian-Ping Yuan et al 2002;Qin et al 2008;Rezanka et al 2013;Sun et al 2008) Canthaxanthin Chlorella vulgaris, Chlorococcum sp.…”

Applied Environmental Biotechnology: Present Scenario and Future Trends

Biorefinery has emerged as a new concept to derive more than one utility product from biomass. The products from biorefinery include one or more biofuels (biodiesel, bioethanol, biomethane, and biohydrogen) along with other energy sources (syngas and bio-oil), pharmaceutical products, and commercially important chemicals. Biorefineries, thus could simultaneously produce biofuels, bio-based chemicals, heat, and power. The biomass production and its utilization as biofuel has a higher water footprint (WF) than fossil derived fuel. The biorefinery approach has the potential to bring down the WF. Similarly, biorefinery approach has the potential to bring down the carbon footprint. The value added product derived from biorefinery basket includes pigments, nutraceuticals, and bioactive compounds. The use of industrial refusals for biomass production includes wastewater as nutrient medium and utilization of flue gases (CO 2 ) as the carbon source for culture of microalgae. These processes have the potential to reduce fresh WF and carbon footprint.
