Many bacteria accumulate poly(3-hydroxybutyrate) (P(3HB)) as an intracellular carbon and energy-reserve material in the form of granules. The fact that P(3HB) macromolecules are enzymically accessible in the granules in vivo but do not serve as a substrate to intracellular depolymerase after granule...
