Amperometric probe for 3-hydroxybutyrate with immobilized 3-hydroxybutyrate dehydrogenase
Analytica Chimica Acta, 1988Abstract The enzyme 3-hydroxybutyrate dehydrogenase is immobilized on a graphite electrode suitable for determination of NADH. Of the several procedures tested for the immobilization, direct adsorption on the electrode surface was most satisfactory, with useful lifetimes of up to 3 days.

An efficient method for the preparation of optically active alkyl (R)-(-)-3-hydroxybutyrates by chemical depolymerization of biopolymer, poly-(R)-(-)-(3-hydroxybutyrate), was established. This method consists of simple recovery of poly-(R)-(-)-(3-hydroxybutyrate) from bacterial cells followed by acidic alcoholysis. When poly-(R)-(-)-(3-hydroxybutyrate)

Anaerobic degradation of poly-3-hydroxybutyrate and poly-3-hydroxybutyrate-co-3-hydroxyvalerate
Biodegradation, 1997The anaerobic degradation of the polyesters poly-3-hydroxybutyrate (PHB) and poly-3-hydroxybutyrate-co-3-hydroxyvalerate (PHBV) was investigated with special regard to intermediate products, kinetics, and yields. During the degradation of PHBV acetate, propionate, n-butyrate, and n-valerate were detected.

AbstractThe thermal decomposition mechanism of maleated poly(3‐hydroxybutyrate) (PHB) was investigated by FTIR and 1H NMR. The results of experiments showed that the random chain scission of maleated PHB obeyed the six‐membered ring ester decomposition process.

A chemical degradation of 3-hydroxybutyric acid
Analytical Biochemistry, 1978Abstract A method is described for degrading 3-hydroxybutyric acid to obtain specifically and in good yield each of its carbons as CO 2 . The hydroxybutyrate is dehydrated to crotonic acid which is reduced to butyric acid. The butyric acid is then degraded stepwise utilizing the Schmidt reaction.

Assay of 3-hydroxybutyrate in the picomolar range
Biochemical Medicine and Metabolic Biology, 1991A radioisotopic procedure for the assay of 3-hydroxybutyrate is presented. It is based on the measurement of NADH, generated in the 3-hydroxybutyrate dehydrogenase reaction, through the conversion of 2-[U-14C]ketoglutarate to 14C-labeled L-glutamate in the presence of beef liver glutamate dehydrogenase.

Polyhydroxyalkanoates (PHAs) represent a group of biopolymers that are synthesized by many bacteria as storage compounds and deposited as insoluble cytoplasmic inclusions. Because they have many putative technical and medical applications, PHAs may play an important role in human life in the future.
