Paramylon, which is exclusively found in euglenoids is already present in the market as a potent immunostimulatory agent. In recent years, a growing number of cytometry approaches have been developed for the screening of E. gracilis mutant strains with an increased lipid content. B Agricult. doi: 10.1016/j.jhazmat.2017.09.008, Giese, E., Dekker, R., Barbosa, A., da Silva, M., and da Silva, R. (2011). 277, 3682536831. The unique ascorbate synthesis pathway from E. gracilis (Figure 2B) has been elucidated using radiotracer experiments, as well as transcriptomic and proteomic studies (Ishikawa and Shigeoka, 2008; O'Neill et al., 2015b; Hasan et al., 2017). The effect of -glucans on porcine leukocytes. There are a few isolated reports on genetic manipulation of E. gracilis. Furthermore, it was shown in vitro and in a mouse model that straight-chain cationic 2-hydroxy-3-(trimethylammonio)propyl paramylon (HTAP) is capable of effectively sequestering bile salts, indicating an anti-diabetic effect, and the bodyweight of obese mice was reduced when the feed was supplemented with 2% (w/w) HTAP (Shibakami et al., 2018). doi: 10.1021/acs.analchem.8b01794, Mussatto, S.I., Dragone, G., Guimares, P.M.R., Silva, J.P.A., Carneiro, L.M., Roberto, I.C., et al.

Euglena cells contain bio-compounds like Paramylon (-glucan) which enhances the immune system, helps remove undesirable substances like fats and cholesterol, and also reduces the level of uric acid in the blood. In another report, the 4-desaturase from E. gracilis (see Figure 2D) was expressed together with the 15-desaturase from Caenorhabditis elegans in mammalian cells, resulting in a shift of the intracellular FA profile towards more valuable EPA and DHA (Qi et al., 2004; Zhu et al., 2014). doi: 10.1007/s11306-014-0687-1, Garca-Garca, J.D., Girard, L., Hernndez, G., Saavedra, E., Pardo, J.P., Rodrguez-Zavala, J.S., 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: 10.1074/jbc.M206756200, Kato, S., Soshino, M., Takaichi, S., Ishikawa, T., Nagata, N., Asahina, M., et al. WEs can be used directly as biodiesel, whereas FAs must be processed first by esterification with an alcohol to yield WEs. Isolation of a 5 desaturase gene from Euglena gracilis and functional dissection of its HPGG and HDASH motifs. These complex carbohydrates can be hydrolysed chemically into their constituent monosaccharide units (e.g., glucose) for subsequent fermentation to bioethanol, or alternatively using enzymes, as harsh chemical conditions can interfere with fermentation (Mussatto et al., 2010; Chen et al., 2013; Al Abdallah et al., 2016). Biosynthesis of docosahexaenoic acid in Euglena gracilis: biochemical and molecular evidence for the involvement of a 4-fatty acyl group desaturase.

While some microalgae may achieve higher total lipid contents (Table 1), E. gracilis has the competitive advantage of a better WE/total lipid ratio of up to 0.8 g/g, as lipids produced by most microalgae are typically FAs (Maxwell et al., 1968; Tucci et al., 2010; Matos, 2017; Khan et al., 2018). (2013). In addition, two research articles [4,5] investigated Euglena gracilis, a photosynthetic flagellate, which had been studied earlier on board of the American Space Shuttle Columbia [6].

Paramylon molecules are arranged as an intermolecular triple helix forming microfibrils, which in turn make up fibres. (2009). The majority of the E. gracilis-derived lipids (WEs and FAs) are suitable for biodiesel production because they are saturated or have a low degree of unsaturation (Rosenberg, 1963; Tucci et al., 2010; Furuhashi et al., 2015). Other current cytometry-based techniques are capable of identifying phenotypes of single cells associated with a high lipid content directly. Paramylon also can act as a potent antioxidant protecting mice from acute hepatic injury induced by CCl4 treatment and was shown to alleviate non-alcoholic steatohepatitis in mice caused by a combination of streptozocin injection and high fat diet when orally administered at a dosage of 1 or 3 g/kg bodyweight (BW) per day, respectively (Sugiyama et al., 2009; Nakashima et al., 2018a).

Therefore, it has been widely applied in many fields, such as in food, supplements, and cosmetics (Gong et al. So far, the highest reported total -tocopherol titres of 44.2 mg/L culture or 1.1 mg/g DW were achieved with E. gracilis in HT fed-batch cultivation after 455 h in a medium containing ethanol as a carbon source (Ogbonna et al., 1998).

Omega-3 fatty acid biochemistry: perspectives from human nutrition. Res. In an alternative approach, genes encoding single enzymes of the E. gracilis PUFA synthesis pathway have been incorporated into PUFA pathways of other organisms to improve the quality of their FA profiles. In recent years, the versatile phototrophic protist Euglena gracilis has emerged as an interesting candidate for application-driven research and commercialisation, as it is an excellent source of dietary protein, pro(vitamins), lipids, and the -1,3-glucan paramylon only found in euglenoids. 28, 817830. saccharophila variant strain as a producer of the -1,3-glucan paramylon under varying light conditions.

Anti-fibrotic activity of Euglena gracilis and paramylon in a mouse model of non-alcoholic steatohepatitis. Eng. Yet, the influence of light was shown to be independent of the presence of chlorophyll, suggesting that mitochondria may be primarily responsible for the regulation of -tocopherol synthesis (Kusmic et al., 1998; Ogbonna et al., 1998; Fujita et al., 2008; Hasan et al., 2017).

For example, the antimicrobial activity of paramylon was enhanced chemically by introducing positively charged groups (e.g., 2-hydroxy-3-trimethylammoniopropyl, N,N-diethylaminoethyl, and N,N-dimethylaminoethyl groups) and sulphated paramylon was shown to exhibit anti-HIV activity (Sakagami et al., 1989; Koizumi et al., 1993). -tocopherol content of greek virgin olive oils. Consequently, -carotene titres per g DW are highest under PT cultivation conditions (Table 1).
