    摘要： Polyhydroxyalkanoate (PHA) that contains a pyrogen such as endotoxin due to a process of producing the PHA is treated to remove the pyrogen by a process that does not affect the inherent chemical and physical properties of the PHA to obtain a biocompatible PHA. PHA produced by fermentation with a Gram negative bacteria can be treated with an oxidizing agent such as hydrogen peroxide or benzoyl peroxide to reduce the endotoxin content to less than 20 endotoxin units/gram of PHA to produce PHA that does not elicit an acute inflammatory response when implanted in an animal. The PHA may have a melting point or glass transition temperature less than 136° C., and can be chemically modified or derivatized such as by covalently coupling an attachment or targeting molecule. The PHA may be used to form various medical devices, and can be used for in vivo applications including tissue coatings, stents, sutures, tubing, bone and other prostheses, bone and tissue cements, tissue regenerating devices, wound dressings, drug delivery, and for diagnostic and prophylactic uses.

    摘要： Methods for the recovery and cation of polyhydroxyalkanoates (PHAs)from biomass containing PHAs, wherein the methods include treating the biomass or partially purified PHA with ozone, in at least one step of a purification process, have been developed. Treatment of PHA-containing biomass or partially purified PHA with ozone yields an enhanced level of purity suitable for coating and other applications. The ozone treatment also has the added advantage that be resulting PHA polymer or polymer latex is essentially odor-free. The ozone treatment may be used alone or in combination with other treatment, extraction, and separation stages, and is especially suitable for the treatment of PHA-containing latexes slurries, suspensions, and organic solutions.
