Biotechnological production of (R)-3-hydroxybutyric acid monomer
Journal of Biotechnology, 2007The escalating problems regarding the treatment of plastic waste materials have led to development of biodegradable plastics. At present, a number of aliphatic polyesters; such as poly[(R)-3-hydroxybutyrate] (PHB), poly(l-lactide), polycaplolactone, poly(ethylene succinate) and poly(butylene succinate) have been developed.

Hypothalamic neuronal activity responses to 3-hydroxybutyric acid, an endogenous organic acid
Brain Research, 1990To elucidate the anorectic action of the endogenous organic acid, 3-hydroxybutyric acid (3-HBA), its effects on neurons in both the rat ventromedial hypothalamic nucleus (VMH) and the lateral hypothalamic area (LHA) were examined. Iontophoretic application of 3-HBA significantly facilitated the firing rate of VMH neurons, whereas facilitation and ...

Catalyst-free valorization of poly-3-hydroxybutyrate to crotonic acid
Reaction Chemistry & Engineering, 2021A novel catalyst-free valorization process of PHB to CA in inert nonpolar solvents is developed. CA was obtained with a yield of 89 wt% and a purity of 91% via a simple consecutive process of pyrolysis at 210 °C and vacuum distillation at 60 °C.

Accumulation of Poly (3-Hydroxybutyric Acid) by Some Soil Streptomyces
Current Microbiology, 1999In a limited-scale survey, 55 soil streptomycetes were screened for the accumulation of poly (3-hydroxybutyrate) [PHB]. Only 18% of the isolates accumulated PHB ranging between 1.9-7.8% of the dry biomass. The promising isolate DBCC-719, identified as Streptomyces griseorubiginosus, accumulated PHB amounting to 9.5% of the mycelial dry mass in the ...

Journal of Microencapsulation, 1995
Microcapsules of poly(3-hydroxybutyric acid) [PHB] and its copolymers with hydroxyvalerate [HV] were prepared by the solvent evaporation technique and loaded with a model drug, 2,7-dichlorofluorescein. Microcapsules were also prepared from the same polymers by incorporating a polyphosphate-Ca+2 complex into the membrane.

Omega oxidation of fatty acids and the pathway of 3-hydroxybutyric acid formation
Archives of Biochemistry and Biophysics, 1978Abstract Pathways followed by the carbons of long chain fatty acids in their conversion to 3-hydroxybutyric acid were traced and the contribution of ω-oxidation to fatty acid oxidation was determined in the cellular environment where ketone body formation occurs.

Abstract We demonstrate a novel strategy to produce ( R )-3-hydroxybutyric acid [( R )-3-HB] using Pseudomonas sp. DS1001a or its extracellular poly (3-hydroxybutyrate) (PHB) depolymerase. While approximately 77.8% PHB was degraded by Pseudomonas sp.

Characterization of Rheological Properties of poly (3-hydroxybutyric acid)
2005 Tampa, FL July 17-20, 2005, 2005To process poly (3-hydroxybutyric acid) (PHB) more efficiently, rheological properties of PHB at different temperatures are needed. There are several fundamentals tests available to characterize PHB such as shear stress as a function of shear rate, stress sweep, frequency sweep and dynamic rheological tests.

Acetic acid and 3-hydroxybutyric acid levels in cerebrospinal fluid of cattle
Animal Science Journal, 2002To evaluate the importance of acetic acid and 3-hydroxybutyric acid (3-HB) in cerebrospinal fluid (CSF) of cattle, CSF samples were taken from a population of 60 cattle including healthy and sick animals with central nervous disorders. Mean acetic acid and 3-HB levels in blood plasma were 0.30 (SD 0.24) and 0.30 (SD 0.28) mM, and those in CSF were 0.14
