“…Lutein is used as dietary supplements and as an animal feed additive (Cai et al 2015). The pigment is capable of serving as a colourant, food/feed additive and immune enhancer (Deenu et al 2013;Miyazawa et al 2013). It is used as a yellow colouration for yellowtail and red sea bream (Maoka 2011), and it imparts a light yellow (yellow tint) colour in red zebra (Yedier et al 2014).…”

Microalgae biomass is used in aquaculture as feed, growth enhancers and immunostimulants. Chlorella vulgaris is an important species with a good biomolecular composition. Commercially, it is one of the most commonly used microalga in aquaculture. Several studies confirmed its ability to improve nutrition, immunity, aquatic bioremediation, amelioration of stress, disease resistance of fish and inhibits bacterial quorum sensing when used appropriately. Despite claims of its benefits, C. vulgaris is reported to have unfavourable effects when incorporated in diets at higher inclusion levels. In addition, its rigid cell wall might restrict the access of digestive enzymes to the intracellular components for proper digestion and assimilation. Thus, this review discusses the role of C. vulgaris and its importance in aquaculture with emphasis on its environmental requirements, morphology, pigments, digestibility, dynamics on growth performance, antibacterial activity, bacterial quorum sensing, immunomodulatory effect, anti‐stress effect, gut microbiome, aquatic bioremediation and its safety as food or feed.

“…Similarly, Deenu et al [156] optimized UAE and UAE combined with enzymatic pretreatment for the recovery of lutein from the green microalga C. vulgaris using RSM. UAE was performed at a frequency of 35 kHz and intensity of 56.58 W/cm 2 using 90% ethanol as an extraction solvent.…”

“…In a study Fan et al [138] showed that UAE combined with subcritical CO 2 extraction is an efficient technique for the extraction of lutein from the microalga, Chlorella pyrenoidosa [138]. The combination of UAE and enzyme-assisted extraction for the extraction of lutein was previously described by Deenu et al [156]. Recently, Parniakov et al [63] found that the sonication pretreatment (60–600 s at power of 400 W and frequency of 24 kHz), followed by pH assisted extraction was efficient in the extraction of carotenoids from Nannochloropsis sp.…”

Innovative Alternative Technologies to Extract Carotenoids from Microalgae and Seaweeds

Marine microalgae and seaweeds (microalgae) represent a sustainable source of various bioactive natural carotenoids, including β-carotene, lutein, astaxanthin, zeaxanthin, violaxanthin and fucoxanthin. Recently, the large-scale production of carotenoids from algal sources has gained significant interest with respect to commercial and industrial applications for health, nutrition, and cosmetic applications. Although conventional processing technologies, based on solvent extraction, offer a simple approach to isolating carotenoids, they suffer several, inherent limitations, including low efficiency (extraction yield), selectivity (purity), high solvent consumption, and long treatment times, which have led to advancements in the search for innovative extraction technologies. This comprehensive review summarizes the recent trends in the extraction of carotenoids from microalgae and seaweeds through the assistance of different innovative techniques, such as pulsed electric fields, liquid pressurization, supercritical fluids, subcritical fluids, microwaves, ultrasounds, and high-pressure homogenization. In particular, the review critically analyzes technologies, characteristics, advantages, and shortcomings of the different innovative processes, highlighting the differences in terms of yield, selectivity, and economic and environmental sustainability.

“…Two grams of C. pyrenoidosa with 90% ethanol was taken in a conical flask, and afterward the jar was held in the ultrasonic tank for extraction at different incubation times and HCL %. Optimization of the ultrasound extraction condition was refined by using the response surface method (RSM) with a central composite design (CCD) (Deenu et al 2013). Three distinct variables (Incubation time, HCL % and biomass concentration) were used at three equidistant levels (-1, 0, and +1) ( Table 1).…”

One of the fundamental carotenoid compounds available in microalga Chlorella pyrenoidosa is lutein, which is a commercially valuable antioxidant compound. The extraction of lutein from C. pyrenoidosa was studied in detail under various operating conditions. Acid pretreatment was done using 10% HCl. To analyze the effectiveness of ultrasound based extraction, experiments were carried out in presence and absence of ultrasonication. The results showed increased lutein yields in presence of ultrasonication. Scanning electron micrographs of pretreated and ultrasonicated algae cells showed increased surface area due to formation of porous surface. There were no significant contrasts in antioxidant activity of lutein between the samples obtained from ultrasound and acid treatment. Furthermore, to optimize the operating parameters like concentration of HCl, ultrasound exposure time and microalga biomass concentration, response surface methodology (RSM) design was applied. From the experimental results the optimum values derived are incubation time 41.34 min, HCl concentration 15.63 % and biomass concentration 309.21 g/L for a yield of 3.5 mg of lutein per gram of algae. Hence, ultrasound extraction with acid treatment is the most efficient technique for the extraction of microalgal lutein.
