Microbes make natural polyester: bacteria

Bacteria manufacture biogedradable polyester by stringing together soluble monomers.

BIOMIMICRY TAXONOMY
Summary
"Bacteria make PHB [polyhydroxybutyrate] and other polyesters the same way nature makes starch: by stringing together soluble monomers and storing the finished polymer product in water-insoluble granules. When needed, the polymer in these granules--which, in the case of PHB, can take up to a whopping 85% of the cell's dry weight--can be broken down quickly and the building blocks reused for energetic or synthetic purposes.” (Yarnell 2004:27)
