In the review polyhydroxyalkanoates characteristic, including poly-β-hydroxybutyrate (P3HB) which is a polymer produced by microorganisms (Ralstonia eutropha — superproducer) is done. Biochemical pathways and conditions of P3HB microbial synthesis have been examined. Thermoplastic features of microbial P3HB in comparison with classic chemical polymers (polyethylene and polypropylene) have been analyzed. It was shown that according to its properties it was the most similar to synthetic polypropylene in comparison to other biopolymers, and it could be its good substitute.
Microbial P3HB ability for biodestruction to CO2 and H2O has shown as extremely perspective property for this polymer usage in different industry branches and for environment saving against anthropogenous pollution.
Key words: poly-β-hydroxybutyrate, biopolymer, Ralstonia eutropha, biosynthesis
