Abstract: Abstract Burkholderia sp. has been reported to synthesize polyhydroxyalkanoates (PHAs) with different monomers such as 3-hydroxybutyrate and 3-hydroxyvalerate. In this study, the PHA synthase gene of B. contaminans Kad1 (phaCBcon) was successfully cloned and characterized.… read more here.

DOI: 10.3390/polym14091725
Abstract: Crystalline and noncrystalline poly(3-hyroxybutylate-co-4-hyroxybutylate) (P(3HB-co-4HB)) were melt blended to obtain mixtures of P(3HB-co-4HB) copolymers. The mixtures and P(3HB-co-4HB) copolymers of different 4HB contents were compared to study the effect of 4HB content on the properties… read more here.
