Preparation and characterization of native poly(3-hydroxybutyrate) microspheres from Ralstonia eutropha
An efficient process for the preparation of poly(3-hydroxybutyrate) (PHB) microspheres with a narrow size distribution was developed. PHB was produced by a fed-batch culture of Ralstonia eutropha using fructose s...

Accumulation of copolyesters consisting of 3-hydroxybutyrate and 3-hydroxyvalerate byAlcaligenes sp. SH-69 in batch culture
AnAlcaligenes sp. SH-69 strain capable of accumulating poly-β-hydroxy-alkanoates(PHAs) from a range of carbon sources was isolated. This organism accumulated copolyesters consisting of 3-hydroxybutyrate and 3-hyd...
