  • Preparation of PHA (polyhydroxyalkanoates) from a citric residue
    Patent number: 8618245
    Abstract: The present invention relates to an obtainment process of biodegradable polymers from a citric residue resulting from the processing of orange juice. The polymers obtained are polyesters classified as polyhydroxyalkanoates including, among them the poly(3-hydroxybutyrate) and poly(3-hydroxybutyrate-co-3-hydroxyvalerate). The biodegradable polymer is obtained from the batch culture process or fed batch culture process with or without recirculation of the cells, using as a carbon source the pre-treated pressing liquor and/or the citric molasses. The polyhydroxyalkanoates, herein described, can be used as substitutes of the synthetic polyesters in different areas, including the food, pharmaceutical, medical, agricultural and other areas.
