“…This statistical comparison of various approaches to improve microalgae productivity (which were summarized in Tables 1–6 and in Supporting information) revealed, that improvements in bioreactor design, such as light passing [ 48,49 ] or air spraying, [ 12 ] produced the highest average increase in microalgae productivity compared to other approaches, such as enhancements of phosphorus or CO 2 fixation, and bacteria co‐cultivation (Figure 2A).…”

“…Microalgae are a group of photosynthetic organisms that are found in different habitats all over the world. [1,2] Nowadays microalgae are increasingly used in industry as a feed for farmed fish or livestock, [3][4][5] as well as the production of food, drugs or drug components such as 𝛽-carotene for humans, [6,7] omega-3 polyunsaturated fatty acid, [8][9][10][11] food colorings including astaxanthin, [7,12] and phycoerythrin, [13][14][15] and many other carotenoid antioxidants with anticancer and anti-inflammatory activities. [16][17][18][19][20] Gene engineered microalgae have been tested in protein drug development [21] and edible vaccine production.…”

Microalgae are considered to be a promising group of organisms for fuel production, waste processing, pharmaceutical applications, and as a source of food components. Unicellular algae are worth being considered because of their capacity to produce comparatively large amounts of lipids, proteins, and vitamins while requiring little room for growth. They can also grow on waste and fix CO2 and nitrogen compounds. However, production costs limit the industrial use of microalgae to the most profitable applications including micronutrient production and fish farming. Therefore, novel microalgae based technologies require an increase of the production efficiencies or values. Here we review the recent studies focused on getting strains with novel characteristics or cultivating techniques that improve production's robustness or efficiency and categorize these findings according to the fundamental factors that determine microalgae growth. Improvements of light and nutrient delivery, as well as other aspects of photobioreactor design, have shown the highest average increase in productivity. Other methods, such as an improvement of phosphorus or CO2 fixation and temperature adaptation have been found to be less effective. Furthermore, interactions with particular bacteria may promote the growth of microalgae, although bacterial and grazer contaminations must be managed to avoid culture failure. The competitiveness of the algal products will increase if these discoveries are applied to industrial settings.

“…Literature data also indicate that lipophilic astaxanthin, which is present mainly in freshwater algae C.a. [ 27 ], easily penetrates cells and is one of the strongest antioxidants, the effectiveness of which is estimated to be up to 100 times higher than that of α-tocopherol [ 83 ]. Moreover, it was found that astaxanthin, among others, participates in the activation and effectiveness of the Nrf2 transcription factor [ 84 , 85 ], which corresponds to these results.…”

UVA radiation leads to oxidative stress and inflammation in skin cells. Therefore, the aim of this study was to compare the effect of lipid extracts from microalgae Nannochloropsis oceanica (N.o.) (marine) and Chlorococcum amblystomatis (C.a.) (freshwater) on the redox balance and PUFA metabolism in human skin fibroblasts modified by UVA. Lipid extracts from both types of microalgae introduced into the fibroblast medium after UVA irradiation significantly reduced the level of ROS and enhanced expression of Nrf2, which increased the activity/level of antioxidants (SOD1/2, CAT, GSH, Trx). The reduction in oxidative stress was accompanied by a decrease in the level of 4-HNE, its protein adducts and protein carbonyl groups. Microalgae also reduced the activity of COX1/2, FAAH and MAGL increased by UVA, and as a consequence, the level of lipid mediators (especially after N.o.) decreased, both from the group of endocannabinoids (AEA, 2-AG, PEA) and eicosanoids (PGE2, 15d-PGJ2, TXB2, 15-HETE), acting mainly through receptors related to G protein, the expression of which increases after UVA. This further contributed to the reduction in oxidative stress and pro-inflammatory signaling at NF-κB and TNFα levels. Therefore, it is suggested that lipid extracts from both N.o. and C.a. microalgae can be used to regenerate fibroblast metabolism disturbed by UVA radiation.

“…are the most ubiquitous and abundant species of Euglenophyta, which are responsible for blooms formed at the water surface during different seasons [ 6 ]. The distinctive euglenoid pigment astaxanthin gives these organisms a distinctive pink or red colour [ 7 , 8 ]. According to scientists [ [9] , [10] , [11] ], astaxanthin is a fat-soluble xanthophyll that is reddish-orange in colour.…”
