Summary A new analog of pantothenic acid (a, y-dihy-droxy-/3, P-dimethylbutyryl-P'-N- methyl alanide) has been prepared and tested for growth effects upon A. suboxydans, L. arabinosus and LM yeast. The compound has no activity for L. arabinosus or LM yeast and from 5--18y0 activity for A. suboxydans. On the basis of evidence obtained it appears that N- methylpantothenic acid does not combine with cellular enzymes in L. arabi-nosus. The ...
