Abstract

SUMMARY: The flagellate requires vitamin B and responds only to those natural forms of the vitamin which are active also for higher animals. The relation between the rate of growth and the concentration of cyano-cobalamin is described an equation of the form of an adsorption isotherm. The ‘inactive’ analogues, pseudovitamin B and Factor A, were taken up by to about the same degree as cyanocobalamin, and inhibited competitively the growth response to cyanocobalamin, apparently by blocking a cell mechanism for ‘binding’ the vitamin.
