Synthesis and accumulation of poly(3-hydroxybutyric acid) by Rhizobium sp.

Acta Biologica Hungarica, 2000
Forty-two Rhizobium strains obtained from different culture collections were evaluated quantitatively for poly(3-hydroxy-butyric acid) [PHB] production in shake flask culture. The majority of the strains produced the maximum amount of PHB during the late exponential or stationary phase of growth.

Simple, stereocontrolled synthesis of 1β-methylcarbapenem antibiotics from 3()-hydroxybutyric acid

Tetrahedron Letters, 1986
Abstract A simple, stereocontrolled synthesis of 1β-methylcarbapenem antibiotics has been accomplished. The synthesis involves stereoselective aldol-type condensation of vinyloxyborane derived from S -phenyl 3( R )-hydroxybutanethioate with N -3-trimethylsilyl-2-propynylidenebenzylamine, regiocontrolled hydroesterification of terminal ...

Cleaner recovery of poly(3-hydroxybutyric acid) synthesized in Alcaligenes eutrophus

Process Biochemistry, 2001
A new cleaner technology for the recovery of poly(3-hydroxybutyrate) (PHB) from Alcaligenes eutrophus is reported. This involves continuously using the recycle-wastewater combined with small additions of surfactant and chelate to recover PHB, treating the final wastewater with hydrochloric acid and activated carbon when the purity of recovered PHB was ...

Hydrolytic degradation of poly[(R)-3-hydroxybutyric acid] in the melt

Polymer, 2005
Abstract Poly[(R)-3-hydroxybutyric acid] [R-P(3HB)] was hydrolyzed in high-temperature and high-pressure water at the temperature range of 180–300 °C and for a period of 360 min. The formation, racemization, and decomposition of 3-hydroxybutyric acids (3HBs) and molecular weight change of R-P(3HB) were investigated.
