Nutritional Value of Lipids in Hydrogenomonas eutropha as Measured in the Rat1


Hydrogenomonas eutropha is known to accumulate lipid, comprised largely of polymerized β-hydroxybutyric acid, when maintained in nitrogen-deficient medium. This lipid was very poorly absorbed by mice from bacteria-containing diets, even though nitrogen absorption was adequate. The monomer, free β-hydroxybutyric acid, was well absorbed from purified diet. Rats fed the monomer or butyric acid ate less food and grew more slowly than rats fed corn oil.
