title: Poly-beta-hydroxybutyric acid in staphylococci.
abstract: Poly-beta-hydroxybutyric acid (PHB) was extracted from various species of staphylococci isolated from different sources. IR and UV spectrophotometry and NMR analysis revealed that the compound consisted only of the beta-hydroxybutyrate. The PHB level in the richest strain among investigated staphylococci is about 64-fold less than in bacilli. The intrinsic viscosity number of this polymer is more than twice greater in the case of the staphylococcal product than that of bacilli.
