Study of Photosynthetic Biosynthesis of Polyhydroxy Butyrate in Anabaena sp. for Future Biomedical Fiber Applications

摘要

INTRODUCTION Polyhydroxybutyrate (PHB) is a carbon storage polymer among heterotrophic bacteria and is the most commonly occurring member of the Polyhydroxyalkanoate (PHA) family of polymers. The synthesis of these energy-rich granules is triggered in the event of deficiency of essential micronutrients such as Nitrogen, Iron, and Phosphorus and it accumulates in the form of intra-cellular inclusions in the cytoplasm of the microorganism.
