Notes
When a streptomycin-bleached mutant of Euglena gracilis strain Z was cultured in the dark at 33, 26, or 15 degrees C, the content of paramylon was higher at lower growing temperature while that of wax esters was higher at higher temperature. Transfer of the cells grown at 33 degrees C - 15 degrees C decreased the wax ester content while increasing the paramylon content; transfer in the reverse direction caused reverse changes. On incubation with labeled acetate, the cells grown at 33 degrees C showed more distribution of radioactivity in wax esters than the cells grown at lower temperatures. Apparently the two energy-reserve substances have different physiological functions.
