Polyhydroxyalkanoates intracellular degradation

Abstract Polyhydroxyalkanoates (PHAs) are energy- and intracellular carbon-storage compounds that can be mobilized and used when carbon is a limiting resource. Intracellular accumulation of PHA enhances the survival of several bacterial species under environmental stress conditions imposed in water and soil, such as UV irradiation, salinity, thermal and oxidative sttess, desiccation, and osmotic shock. The ability to endure these sttesses is linked to a cascade of events concomitant with PHA degradation and the expression of genes involved in protection against...
