In contrast, some vegetable oils (e.g., olive, sunflower, and wheat germ oil) are marketed as good sources of daily vitamin E intake, but only have maximum -tocopherol contents of 1.5 mg/g (Table 1), which further emphasises the commercial potential of E. gracilis as a viable candidate for industrial -tocopherol production (Psomiadou et al., 2000; US Department of Agriculture., 2018). Paramylon is uniquely produced by euglenoids, deposited as granules in the cytosol, and readily degraded and utilised as a carbon source under carbon starvation (Malkoff and Buetow, 1964; Kiss et al., 1986; Barsanti et al., 2001; Monfils et al., 2011).

Anti-fibrotic activity of Euglena gracilis and paramylon in a mouse model of non-alcoholic steatohepatitis. Front. Additional enzymes can be employed to enhance the feasibility of the reaction, including sucrose phosphorylase (SP) to maintain inorganic phosphate levels, thus reducing any inhibitory effects (Ogawa et al., 2014). Compared to some -tocopherol methyltransferases from plants, the E. gracilis enzyme has a high KM value (50 M for SAM) and low specific activity (251 nmol/h per mg protein for -tocopherol) (Shigeoka et al., 1992; Koch et al., 2003). Reports on industrial-scale HT cultivation of E. gracilis in controlled bioreactors have been only conceptual so far. (2012). The proposed activity of 17-desaturase and C20/22 elongase (see Figure 2D) has been verified in E. gracilis cell extract only, whereas genes encoding the other enzymes (see Figure 2D) have been expressed heterologously (Wallis and Browse, 1999; Meyer et al., 2003; Qi et al., 2004; Damude et al., 2010; Pollak et al., 2012; Zhu et al., 2014).

(2001). Therefore, it has been widely applied in many fields, such as in food, supplements, and cosmetics (Gong et al. Euglena Euglena, genus of more than 1,000 species of single-celled flagellated (i.e., having a whiplike appendage) microorganisms that feature both plant and animal characteristics. Additionally, -1,3-glucans have been shown to lower cholesterol levels and exhibit antidiabetic, antihypoglycemic and hepatoprotective activities; they have also been used for the treatment of colorectal and gastric cancers (Ooi and Liu, 2000; Kataoka et al., 2009; Barsanti et al., 2011). doi: 10.1371/journal.pone.0195329, Watanabe, T., Shimada, R., Matsuyama, A., Yuasa, M., Sawamura, H., Yoshida, E., et al. Until now, the research on the health benefits of paramylon has focussed mainly on applications to treat human conditions, but it has been suggested that it also could be beneficial to livestock and fish health. doi: 10.1104/pp.103.034223, Ntefidou, M., Ldtke, T., Ahmad, M., and Hder, D.-P.

Mater. Bioproducts from E. gracilis can be produced under various cultivation conditions discussed in this review, and their yields are relatively high when compared with those achieved in microalgal systems. Chemical derivatives of paramylon (activated paramylon) have been shown to exhibit augmented or novel bioactivities. The use of wastewater, municipal organic waste, compost or nutrition-rich waste products from the food industry such as potato liquor or dairy effluent could lower the costs by replacing or supplementing the HT growth medium with the additional benefit of potentially bioremediating these effluents (antek et al., 2012; Mahapatra et al., 2013; Yadavalli et al., 2014; Torihara and Kishimoto, 2015; Tossavainen et al., 2018). doi: 10.1111/bcp.13496. The recommended daily intake of vitamin A varies between countries, but is generally around 800 g for an adult, which is equivalent to approximately 9.6 mg of the provitamin -carotene or around 3 g of dehydrated E. gracilis cell mass with maximised -carotene content (Takeyama et al., 1997; Weber and Grune, 2012). Front. Light dependency of resistance to ionizing radiation in Euglena gracilis. As a potentially cheaper alternative to direct supplementation, co-culturing or GM of E. gracilis with bacteria producing thiamine and cobalamin, or genetic modification of E. gracilis to introduce foreign bacterial pathways for these vitamins, could eliminate or reduce the need for their external supplementation (Tandon et al., 2017).

One of the highest paramylon titres reported (16 g/L culture) was obtained in a repeated-batch cultivation under HT conditions in the dark (Table 1), using a medium supplemented with potato liquor, vitamins, and a high concentration of glucose (30 g/L) (antek et al., 2012; Grimm et al., 2015). doi: 10.1093/oxfordjournals.pcp.a077454, Sun, A., Hasan, M.T., Hobba, G., Nevalainen, H., and Te'o, J. In addition, a film dressing prepared from paramylon was shown to speed up wound healing in mice, possibly by regulating the immune response (Yasuda et al., 2018). doi: 10.3390/antiox6040099, Fujita, T., Aoyagi, H., Ogbonna, J.C., and Tanaka, H.

Moreover, feeding male rats with 20 mg paramylon/kg BW daily was shown to improve the quality of their sperm (e.g., motility, vitality, and acrosome integrity) (Ak Sonat et al., 2018). doi: 10.1016/j.algal.2017.04.028, Behera, S., Singh, R., Arora, R., Sharma, N.K., Shukla, M., and Kumar, S. (2014). In the present study, we isolated the cDNA encoding MMAA from Euglena gracilis Z, a photosynthetic flagellate. The in vitro synthesis of soluble -1,3-glucans could be an alternative to the hydrolysis approach. So far, only two E. gracilis enzymes involved in paramylon degradation have been characterised, an endo--1,3-glucanase and a laminaribiose phosphorylase (LBP)/-1,3-glucan phosphorylase (-1,3-GP) involved in paramylon degradation have been characterised (Vogel and Barber, 1968; Takeda et al., 2015; Kuhaudomlarp et al., 2018).

Energy Res. Biomass nutrient profiles of three microalgae: Spirulina platensis, Chlorella vulgaris, and Isochrisis galbana.

Washington, DC: United States Patent and Trademark Office. Barras, D.R., and Stone, B.A. There are several factors influencing -tocopherol levels in E. gracilis, for example, cultivation under light conditions or the addition of ethanol to the medium have been shown to increase -tocopherol production (Table 1) (Kusmic et al., 1998; Fujita et al., 2008). It has already been used on a commercial scale for ingredients in foods and cosmetics and has undergone research in other fields too. Eng.

(2003). Identifying what control mechanisms make E. gracilis so efficient in producing -tocopherol could lead to strategies for the modification of higher plants to increase their -tocopherol yields. Wax ester synthase/diacylglycerol acyltransferase (EgWSD) isozymes have been shown to fulfil a role similar to that of EgWS.

Attempts to enhance E. gracilis biomass production under PT conditions, for example with the use of a photobioreactor, resulted in maximum titres similar to those of shake flask cultures, which are several times lower than those of some microalgal species grown under closed PT conditions (Table 1) (Richmond et al., 2003; Chae et al., 2006; Hasan et al., 2017). However, unlike higher plants, E. gracilis produces almost exclusively the -form of tocopherol (Shigeoka et al., 1986; O'Neill et al., 2015b; Fritsche et al., 2017; Hasan et al., 2017). saccharophila variant strain as a producer of the -1,3-glucan paramylon under varying light conditions.

Oral delivery and gastrointestinal absorption of soluble glucans stimulate increased resistance to infectious challenge. E. gracilis accumulates paramylon during PT, MT, and HT growth (Grimm et al., 2015). The flagellum they use for locomotion, which is slightly shorter than its body, beats by spinning at 40 Hz in close proximity to the cell body ().As for most flagellates, the swimming motion of E. gracilis is rototraslatory and inherently 3D.
