PHAs are natural polyesters of organic acids. In nature, they serve as energy storage for many microorganisms. Polyhydroxyalkanoates can be composed of more than 150 types of monomers, which in combination provide a large variety of materials with different properties. Currently, we produce poly-3-hydroxybutyrate (P3HB).
P3HB is of bacterial origin and bacteria (and other organisms) can also degrade it. Waste from P3HB does not persist in the environment but decomposes rapidly.
Safe to human
P3HB is well accepted by the human body – it does not cause any irritation or immune response. This makes P3HB a perfect material not only for biomedicine and tissue engineering but also for cosmetics.
