GONZALEZ GARCIA, Yolanda; MEZA CONTRERAS, Juan Carlos; GONZALEZ REYNOSO, Orfil  y  CORDOVA LOPEZ, Jesús Antonio. Synthesis and biodegradation of polyhydroxialkanoates: Bacterially produced plastics. Rev. Int. Contam. Ambient [online]. 2013, vol.29, n.1, pp.77-115. ISSN 0188-4999.

Polyhydroxyalkanoates (PHA) are biopolyesters synthesized by numerous microorganisms as an intracellular carbon and energy storage compound, and they have physical and chemical properties similar to those of petroleum-based plastics. They have been extensively studied since 1980, nowadays they are still an important research topic as substitutes of conventional plastics since PHA are biodegradable and synthesized from renewable resources. They also have an important application as biocompatible materials in the biomedical and pharmaceutical field. In this work is presented an extensive bibliographic review about scientific research on the biosynthesis and biodegradation of PHA, the status of its industrial production and commercialization, and the future perspectives regarding the study and application of these bioplastics.

Palabras llave : Polyhydroxyalkanoates; polyhydroxybutyrate; depolymerase; biopolyesters.
