“…On the world market, there is an increase in interest in carotenoids from natural sources, including microalgae [11]. Microalgae such as Dunaliella salina, Haematococcus lacustris (=Haematococcus pluvialis), and some Chlorella are rich sources of carotenoids [37,38,48,66]. In microalgae capable of both autotrophic and heterotrophic growth (for example, Haematococcus lacustris and Chromochloris zofingiensis, formerly known as Chlorella zofingiensis), heterotrophic conditions can significantly increase the productivity of biomass, but they cannot provide large amounts of pigments, including commercially valuable ones [120].…”

Exposure to high-intensity lighting increases carotenoid production in Haematococcus lacustris [37,121], Dunaliella salina [48,79], Chromochloris zofingiensis [122], Tetradesmus obliquus [123], Nostoc calcicola [124], etc. (Table 5).…”

“…It is reported that when exposed to stressful conditions, some microalgae synthesize and accumulate astaxanthin in significant quantities [68]. Known astaxanthin producers are Haematococcus lacustris [37,121,130,131], and Chromochloris zofingiensis [122,132,133]. Smaller amounts of astaxanthin were found in Neochloris wimmeri, Scenedesmus vacuolatus [125], and Chlamydomonas nivalis [134].…”

“…In this case, the lighting conditions can be changed and this can be used to increase the productivity of microalgae biomass and the accumulation of valuable compounds in it. An urgent task in the microalgae cultivation is to minimize the energy costs for providing lighting, since they largely determine the cost of compounds obtained from microalgae [37]. The main parameters characterizing the lighting conditions are light intensity, duration of lighting, and the use of rays of different spectral composition.…”

Microalgae are a valuable natural resource for a variety of value-added products. The growth of microalgae is determined by the impact of many factors, but, from the point of view of the implementation of autotrophic growth, light is of primary importance. This work presents an overview of the influence of light conditions on the growth of microalgae, the content of lipids, carotenoids, and the composition of fatty acids in their biomass, taking into account parameters such as the intensity, duration of lighting, and use of rays of different spectral composition. The optimal light intensity for the growth of microalgae lies in the following range: 26−400 µmol photons m−2 s−1. An increase in light intensity leads to an activation of lipid synthesis. For maximum lipid productivity, various microalgae species and strains need lighting of different intensities: from 60 to 700 µmol photons m−2 s−1. Strong light preferentially increases the triacylglyceride content. The intensity of lighting has a regulating effect on the synthesis of fatty acids, carotenoids, including β-carotene, lutein and astaxanthin. In intense lighting conditions, saturated fatty acids usually accumulate, as well as monounsaturated ones, and the number of polyunsaturated fatty acids decreases. Red as well as blue LED lighting improves the biomass productivity of microalgae of various taxonomic groups. Changing the duration of the photoperiod, the use of pulsed light can stimulate microalgae growth, the production of lipids, and carotenoids. The simultaneous use of light and other stresses contributes to a stronger effect on the productivity of algae.

“…H. pluvialis contains about 5% of astaxanthin (dry weight) and its production is regulated by different stress conditions and its related with H, pluvialis cell cycle [23] . Several studies have shown that high light intensity, high salinity of the medium, pH, temperature, and lack of nutrients, stimulate H. pluvialis to produce astaxanthin [24] , [25] , [26] , reaching even about 7% in soils poor in phosphorus [27] or thank to a photoautotrophic induction [28] . Astaxanthin production usually occurs in two different stages [29] .…”

Large-scale cultivation of microalgae for the production of high-value compounds raises concerns on sustainability due to intense consumption of water resources. Use of wastewater for microalgae cultivation is considered a promising alternative, because it not only reduces water consumption, but also provides nutrients required for microalgae growth. In the present study, Haematococcus pluvialis and Chromochloris zofingiensis were cultivated in synthetic dairy wastewater (DWW) to identify the potential of developing highvalue product first biorefineries, with astaxanthin as the main product.H. pluvialis and C. zofingiensis cultivated in DWW achieved biomass concentrations of 0.55 ± 0.01 and 0.65 ± 0.01 g/L, respectively. Astaxanthin contents of 2.1 ± 0.1% and 0.4 ± 0.1% were observed in H. pluvialis and C. zofingiensis grown in DWW. Minimum freshwater consumption for cultivation was 69.93 L/g astaxanthin in control growth media, which could be eliminated by cultivation of microalgae in DWW. COD, TN, and TP removal efficiencies were in the range of 94%-96%, 79%-81%, and 57%-79%, respectively, indicating capability for simultaneous biomass production and phycoremediation. Presence of carbohydrates and lipids in residual biomass suggested the applicability as feedstock for biorefining. Potential avenues to integrate wastewater treatment, astaxanthin production, and valorization of residual biomass were discussed in context of high-value product first biorefineries.
