cells. In view of the known function of this coenzyme 

 in fat formation (8) this seems reasonable. Other activities, 

 such as glucose oxidation, appear not to be influenced 

 by coenzyme A deficiency, although the oxidation of glyc- 

 erol is markedly reduced (see Fig. 1.1) (9) in a manner 

 that is not yet understood.

Fig. 1.1. Glycerol oxidation by pantothenate-deficient A. suboxydans 

 cells. Deficient cells were grown in 0.0006 y pantothenic acid equiv- 

 alent per milliliter of medium. This concentration permitted growth 

 of only 0.33 g. per liter, in contrast to sufficient cells which were grown 

 in excess CoA and yielded a crop of over 1 g. per liter.
