There are strong indications that this pretreatment of paramylon has the effect of an increase in stimulation of leucocytes and hepatoprotection, probably because the -1,3-glucan triple-helices of paramylon are disrupted in the process and the apparently more bioactive single helices are thereby exposed (Kataoka et al., 2002; Kusmic et al., 2018). doi: 10.1111/j.1365-2621.2003.tb09615.x, Tomiyama, T., Kurihara, K., Ogawa, T., Maruta, T., Ogawa, T., Ohta, D., et al.

In principle, enzymatic hydrolysis and conversion processes could be applied to paramylon. (2018). Various industrial applications have been proposed for paramylon, including its use as a substrate for thermoplasticisation. Accordingly, the cells synthesise FAs, fatty alcohols (FAlcs) and ultimately WEs in larger quantities from paramylon under oxygen-limiting conditions (Inui et al., 1984; Tucci et al., 2010; Furuhashi et al., 2015; Yoshida et al., 2016).

Euglena gracilis is rich in nutrients and high-value metabolites. Paramylon is the water-insoluble storage polysaccharide of E. gracilis, which consists of -1,3-linked glucose subunits, and has an estimated molecular weight between 100 and 500 kDa (Figure 3A) (Miyatake and Kitaoka, 1983; Koizumi et al., 1993; Barsanti et al., 2011).

Osaka Prefecture Ser. Euglena gracilis, which began to appear 500 million years ago, is a species of unicellular organisms that live mostly in freshwater ( Goto and Beneragama, 2010) and has no cell walls, giving it dual characteristics of plants and animals, which enable this microalga to adopt photosynthetic, heterotrophic, and mixotrophic conditions during doi: 10.1111/jpy.12758, Sutivisedsak, N., Leathers, T.D., Bischoff, K.M., Nunnally, M.S., and Peterson, S.W. 2019). They also act as a dietary fibre and have been shown to lower blood cholesterol levels (Nakashima et al., 2018b). Recent insights into the complex metabolism of E. gracilis have highlighted unique metabolic pathways, which could provide new leads for product enhancement by genetic modification of the organism. Vitamin C (ascorbate) is critical for human health as it acts as an antioxidant and co-factor for several enzymes involved in essential biosynthesis pathways (Grosso et al., 2013; Aghajanian et al., 2015). (2004). The journal Frontiers in Nutrition published a paper on the results of our joint research with Waseda University, which reported that the body clock in (2018b). Comparable levels of 40 mg/L culture or 3.7 mg/g DW were reached after a relatively short incubation time of 120 h using a bleached strain in HT batch cultivation with a medium supplemented with ethanol, glutamate and malate (Rodrguez-Zavala et al., 2010). 97, 322329. It should be noted that ascorbate production by E. gracilis has not attracted much attention, probably because consumption of just 100 to 200 mL of juice from citrus fruits like oranges (Table 1) is enough to fulfil the daily recommended intake of adults (75 and 90 mg for females and males, respectively) (Grosso et al., 2013; US Department of Agriculture., 2018). 54, 255259.

This work was supported by the Australian Research Council Industrial Transformation Training Centre funding scheme (Project Number: IC130100009). Br. Biomed. Euglena gracilis is used as model organism for various microbiological, molecular biological and biotechnological studies. The overall titre can be increased to 86.5 mg/L culture by the fed-batch two-step (MT to PT) cultivation method discussed above (Takeyama et al., 1997). doi: 10.1104/pp.103.034223, Ntefidou, M., Ldtke, T., Ahmad, M., and Hder, D.-P. (2006). These yields were up to 10-fold higher than those obtained from microalgae such as Chaetomorpha litorea, Chlamydomonas reinhardtii, Durvillaea antarctica, Macrocystis pyrifera, and Scenedesmus obliquus (Table 1) (Behera et al., 2014).

PT cultivation of E. gracilis is currently favoured, probably due to lower cost and relative ease of set-up, but HT cultivation for higher yields of cell mass and paramylon could soon become reality. (2013). For example, dried E. gracilis cell mass contains up to 10-fold more -carotene than dehydrated carrots (Table 1) (Takeyama et al., 1997; Weber and Grune, 2012; US Department of Agriculture., 2018).

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).

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). 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). (2001). Euglena gracilis shows an absolute requirement for vitamins B1 (thiamine) and B12 (cobalamin), so complex E. gracilis media usually contain at least 50 ng/L and 10 ng/L, respectively, of these compounds (Isegawa et al., 1987; Shigeoka et al., 1987; Croft et al., 2005; Hasan et al., 2017).
