Mixotrophic Cultivation Optimization of Microalga Euglena pisciformis AEW501 for Paramylon Production.

ABSTRACT: Euglena, a flagellated unicellular protist, has recently received widespread attention for various high-value metabolites, especially paramylon, which was only found in Euglenophyta. The limited species and low biomass of Euglena has impeded paramylon exploitation and utilization. This study established an optimal cultivation method of Euglena pisciformis AEW501 for paramylon production under mixotrophic cultivation. The results showed that the optimum mixotrophic conditions were 20 °C, pH 7.0, and 63 μmol photons m^-2∙s^-1, and the concentrations of sodium acetate and diammonium hydrogen phosphate were 0.98 g L^-1 and 0.79 g L^-1, respectively. The maximal biomass and paramylon content were 0.72 g L^-1 and 71.39% of dr
