Abstract
Euglena gracilis is shown to be able to grow on potato liquor as the main medium component leading to an interesting biotechnological product represented by paramylon - a beta-1,3-glucan - and, at the same time, revaluating an otherwise annoying waste stream of the potato-starch industry. Paramylon mass fractions of about 75% are obtained for biomass concentrations of 15 g/L during simple batch cultivation under heterotrophic conditions. Supplementation of the growth medium with glucose and the vitamins B-1 and B-12 are shown to improve growth rate as well as paramylon content. E. gracilis grows best at about 27.5 degrees C without requiring pH control.
