  • What is the biosynthesis pathway of PHA?

    PHA biosynthesis is performed via three well known and most described pathways, TCA cycle, fatty acid ?-oxidation pathway, and fatty acid de novo biosynthesis pathway in which acetyl-CoA is the main precursor in PHA biosynthesis.

  • How are Polyhydroxyalkanoates produced?

    PHAs are polyesters synthesized and stored by various bacteria and archaea in their cytoplasm as water-insoluble inclusions.
    PHAs are usually produced when the microbes are cultured with nutrient-limiting concentrations of nitrogen, phosphorus, sulfur, or oxygen and excess carbon sources.

  • What are Polyhydroxyalkanoates or PHAs?

    Polyhydroxyalkanoates (PHAs) are intracellular microbial polyesters synthesized by many species of Bacteria and Archaea, generally under nutrient limitation and excess of carbon source as storage granules of energy and also conferring stress resistance to prokaryotes.

  • What are Polyhydroxyalkanoates or PHAs?

    The fermentative production of PHAs is normally operated as a two-stage fed-batch process (Doi 1990).
    An initial growth phase in nutritionally enriched medium yields sufficient biomass, followed by a product formation phase in nitrogen-depleted medium.
