Notes:
Some conditions for optimum accumulation of vitamin B12 by resting Euglena gracilis cells were studied. Accumulation involves intracellular binding, as confirmed by disruption of the cells and differential centrifugation. At least 70% of the intracellular B12 was attached to sedimentable particles, apparently to the mitochondrial and cell wall-membrane fractions. The latter contains a heat-labile substance which rapidly binds B12.
