Lipid fractions of propane- andn -butane-grown nocardial cells each contain a chloroform-soluble, ether-insoluble polymer not observed previously in liquidn -alkane-grown cells. The polymer in propane-grown cells is poly-β-hydroxybutyrate. The polymer inn -butane-grown cells apparently contains unsaturation in the molecule, and is identified tentatively as a co-polymer of β-hydroxybutyric and β-hydroxybutenoic (specifically 3-hydroxy 2-butenoic) acids. The other major component of the lipid fraction consists of triglycerides containing principally palmitic and stearic acids. There seems to be little qualitative distinction in the glycerides of propane- orn -butane-grown cells. Oxidative assimilation ofn -butane is described.
