Unfortunately, the product yield of this reaction has not been reported (Bumer et al., 2001). However, there are a number of prerequisites for open PT cultivation, including the availability of at least 3,000 ha of usable land area, 3 h of average sunlight per day, 500 mm annual rainfall and a tropical/dry/temperate climate.

Cultivation under strict HT conditions leads to increased paramylon levels during the exponential growth phase, while light has been shown to be detrimental to the accumulation and conservation of paramylon under MT growth, probably because the metabolic switch to paramylon degradation is under the influence of a photoreceptor (Kiss et al., 1986; Barsanti et al., 2001).

Therefore, it has been widely applied in many fields, such as in food, supplements, and cosmetics (Gong et al. Osaka Prefecture Ser. 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). Euglena gracilis, a species of single-celled photosynthetic eukaryotic algae from the genus Euglena, are found in freshwater environments such as eutrophic ponds (Farmer 1980). (2013).

However, at present, most studies only extract the paramylon of E. gracilis, which is a waste of resources.In this study, a method of sequential extraction of lipid and paramylon from E. gracilis was studied, and the extraction conditions were optimized. 426, 125134. J. Furthermore, there is a preference for the use of short- or medium-chain esters over long-chain esters in the industrial production of diesel and kerosene because shorter esters provide better cold flow properties and oxidative stability (Maurice et al., 2001). E. gracilis is of considerable environmental importance and biotechnological value: it can survive a variety of carbon resources, toxic chemicals, and adverse environmental conditions such as.

To maximise the bioactive potential of paramylon, the granules could be hydrolysed to soluble shorter-chain -1,3-glucans, which may lead to an increased blood plasma availability and a stronger or different immune response compared to an insoluble preparation (Rice et al., 2005). Its most studied wild-type strains are Z and bacillaris, but their discrimination by standard molecular methods is difficult.Therefore, we decided to test the suitability of MALDI-TOF MS (matrix-assisted laser desorption/ionization-time of flight mass spectrometry .

A solution to this problem could be the genetic modification (GM) of E. gracilis to improve biomass and/or bioproduct yields. 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). doi: 10.1021/jf990993o, Qi, B., Fraser, T., Mugford, S., Dobson, G., Sayanova, O., Butler, J., et al. 9, 368373. Bioresource Technol. For example, transformation of E. gracilis chloroplasts with the gene coding for a cyanobacterial fructose-1,6-/sedoheptulose-1,7-bisphosphatase has been achieved by biolistic bombardment (Doetsch et al., 2001; Ogawa et al., 2015).

From first- to third-generation biofuels: challenges of producing a commodity from a biomass of increasing complexity. Bioresource Technol. Unlocking the biological potential of Euglena gracilis: evolution, cell biology and significance to parasitism. Algal Res. A better understanding of the E. gracilis pathway for -carotene biosynthesis (Figure 2A) could hold the key to further improve the yields. PT cultivation induces the synthesis of ascorbate in E. gracilis as a mechanism to cope with reactive oxygen species (ROS) produced during photosynthesis (ROS scavenging). 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). Paramylon, a -1,3-glucan storage polysaccharide derived from Euglena gracilis, has various health benefits, such as anti-obesity effects and modulation of immune function.However, whether paramylon intake affects the circadian clock remains unknown. Other organisms, mostly belonging to the fungal genera Trichoderma and Aspergillus, have been explored as alternative sources for paramylon-degrading enzymes. Determination of the nutritive value of Euglena gracilis protein by in vitro digestion experiments and rat feeding tests. 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). Biochem. Recent advances in our understanding of tocopherol biosynthesis in plants: an overview of key genes, functions, and breeding of vitamin E improved crops. The roles and mechanisms of actions of vitamin C in bone: new developments. 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). J. Biochem. Phycol. Biotechnol. These factors need to be taken into account when determining the most favourable time of harvest. AG was supported by an international Macquarie University Research Excellence Scholarship. The 8-desaturase of Euglena gracilis: an alternate pathway for synthesis of 20-carbon polyunsaturated fatty acids. The technical set-up of a cultivation also plays an important role in -tocopherol production, for example, hydrodynamic stress caused by fast stirring with baffled plates in a bioreactor cultivation has been shown to have a detrimental effect on the final yields of -tocopherol during HT cultivation (Ogbonna et al., 1998). 16, 112. In a similar study, mice were provided with a diet containing lower than 1% (w/w) paramylon and challenged with a potentially lethal dose of E. coli. (2017). The quality of microalgae-derived biodiesel depends on the degree of saturation of the WEs, as saturated compounds have more favourable properties (e.g., higher cetane number) (Ramos et al., 2009; Andreani and Rocha, 2012). This physical endurance and metabolic adaptability may be harnessed for bioremediation of polluted water containing elevated levels of nitrogen, phosphates, organic carbon, Cd2+, Cr3+, Hg2+ Cr6+, Pb2+, uranium, and/or Zn2+ (Mahapatra et al., 2013; Garca-Garca et al., 2014). Euglena gracilis has a pathway for the synthesis of EPA and subsequently DHA (Figure 2D), and the enzymes within this pathway have been characterised biochemically. (2018b). doi: 10.1023/a:1008022305865, Kusmic, C., Barsanti, L., Di Lascio, N., Faita, F., Evangelista, V., and Gualtieri, P. (2018).

For example, expression of the Synechococcus elongatus PCC 7942 fructose-1,6-/sedoheptulose-1,7-bisphosphatase gene in E. gracilis chloroplasts was shown to significantly enhance its photosynthetic activity, as well as the paramylon yield (by almost 2-fold), the WE yield under anaerobic conditions (~100-fold) and the biomass yield (~2-fold) (Ogawa et al., 2015). However, the current chemical synthesis of oligosaccharides is still laborious and product yields are very low despite some advances in the field, whereas enzymatic synthesis has been considered as a technically feasible option (Plante et al., 2001; Ogawa et al., 2014).
