“…In a recent study, PLE (preheating: 1 min, heating: 5 min, flush volume: 60%, nitrogen purge: 60 s, pressure: 103.4 bars, 0.5 g sample/20 mL solvent, 40 • C, 15 min extraction time) was successfully used for the recovery of carotenoids from dried microalgae (Chlorella vulgaris, Phaeodactylum tricornutum, and Spirulina maxima) using DMSO as extraction solvent. A significant increase in carotenoid extraction compared to conventional extraction (maceration with the same sample-to-solvent ratio, temperature, extraction solvent, and extraction time) was observed, being approximately 3, 3.3, and 5.9 times higher in C. vulgaris, P. tricornutum, and S. maxima, respectively [34]. In another study, similar findings were found in freeze-dried Spirulina extracted with DMSO (100%) via PLE and conventional extraction.…”

Carotenoids are ubiquitous and versatile isoprenoid compounds. The intake of foods rich in these pigments is often associated with health benefits, attributable to the provitamin A activity of some of them and different mechanisms. The importance of carotenoids and their derivatives for the production of foods and health-promotion through the diet is beyond doubt. In the new circular economy paradigm, the recovery of carotenoids in the biorefinery process is highly desirable, for which greener processes and solvents are being advocated for, considering the many studies being conducted at the laboratory scale. This review summarizes information on different extraction technologies (ultrasound, microwaves, pulsed electric fields, pressurized liquid extraction, sub- and supercritical fluid extraction, and enzyme-assisted extraction) and green solvents (ethyl lactate, 2-methyltetrahydrofuran, natural deep eutectic solvents, and ionic liquids), which are potential substitutes for more toxic and less environmentally friendly solvents. Additionally, it discusses the results of the latest studies on the sustainable green extraction of carotenoids. The conclusions drawn from the review indicate that while laboratory results are often promising, the scalability to real industrial scenarios poses a significant challenge. Furthermore, incorporating life cycle assessment analyses is crucial for a comprehensive evaluation of the sustainability of innovative extraction processes compared to industry-standard methods.

“…Pigments' content was calculated by the formulas (Staruhina et al, 2021;Gan et al, 2022). Chlorophyll or carotenoids were calculated by the formula (Wang et al, 2022). Total chlorophyll was defined as the sum of chlorophyll a and chlorophyll b concentrations.…”

Background: Droughts during the growing season are becoming increasingly common due to climate change and global warming. The study’s goal study was to assess the adaptation mechanisms of C. coggygria Scop. under simulated water deficit conditions using indicators characterized changes in the leaf stomatal apparatus and photosynthesizing system. Methods: The influence of osmotic polyethylene glycol 6000 on the research object C. coggygria regenerants was studied in vitro. Such indicators as morphological changes, pigment content, stomatal density and size and stomatal slit size were quantified. Result: Due to the influence of osmotic stress, there was a pigment content increase in the leaf plate on osmotic media. Stomatal density raised by 27.0-29.8% in explant cells cultivated on PEG 4.0-6.0%. Under the osmotic influence, there was a drop in the stomatal cells’ area and shape and the ratio of stomatal length to width in the regenerant leaves decreased from 1.5 to 1.0-1.1. These results indicate the adaptation of C. coggygria regenerants to stress caused by an artificial drought in vitro. The changes’ identification in the stomatal apparatus and the C. coggygria pigment ratio will accelerate the selective screening of drought-resistant plants for use in protective forestry.Background: Droughts during the growing season are becoming increasingly common due to climate change and global warming.

“…This low productivity is one of the main problems in the industrial production of microalgae, which makes its competition with synthetic systems difficult. On the other hand, although there is much research about the use of emerging technologies (pressurized liquid extraction, pulsed electric fields, moderate electric fields, high-voltage electric discharges, high-pressure homogenization, microwave-assisted extraction, subcritical fluid extraction, and supercritical fluid extraction, among others) for the extraction of microalgal carotenoids [ 214 , 215 ], their industrial scaling-up remains a bottleneck. These concerns are the main challenge for future research in microalgal biotechnology to produce a more efficient and sustainable industry for the natural production of carotenoids from microalgae.…”

Carotenoids are a large group of health-promoting compounds used in many industrial sectors, such as foods, feeds, pharmaceuticals, cosmetics, nutraceuticals, and colorants. Considering the global population growth and environmental challenges, it is essential to find new sustainable sources of carotenoids beyond those obtained from agriculture. This review focuses on the potential use of marine archaea, bacteria, algae, and yeast as biological factories of carotenoids. A wide variety of carotenoids, including novel ones, were identified in these organisms. The role of carotenoids in marine organisms and their potential health-promoting actions have also been discussed. Marine organisms have a great capacity to synthesize a wide variety of carotenoids, which can be obtained in a renewable manner without depleting natural resources. Thus, it is concluded that they represent a key sustainable source of carotenoids that could help Europe achieve its Green Deal and Recovery Plan. Additionally, the lack of standards, clinical studies, and toxicity analysis reduces the use of marine organisms as sources of traditional and novel carotenoids. Therefore, further research on the processing of marine organisms, the biosynthetic pathways, extraction procedures, and examination of their content is needed to increase carotenoid productivity, document their safety, and decrease costs for their industrial implementation.
