A Closer Look on the Polyhydroxybutyrate- (PHB-) Negative Phenotype of Ralstonia eutropha PHB-4

PLoS ONE, 2014
The undefined poly(3-hydroxybutyrate)- (PHB-) negative mutant R. eutropha PHB-4 was generated in 1970 by 1-nitroso-3-nitro-1-methylguanidine (NMG) treatment. Although being scientific relevant, its genotype remained unknown since its isolation except a recent first investigation.

Polyhydroxybutyrate production using agro-industrial residue as substrate by Bacillus sphaericus NCIM 5149

Brazilian Archives of Biology and Technology, 2009
The aim of this work was to study the production of polyhydroxybutyrate (PHB) using agro- industrial residues as the carbon source. Seven substrates, viz., wheat bran, potato starch, sesame oil cake, groundnut oil cake, cassava powder, jackfruit seed ...

Bioprocessing of Damaged Wheat Grain Into PHB Using <i>Lactobacillus</i> Fermentation Following Optimized Acid Hydrolysis. [PDF]

Food Sci Nutr
336.66 mg/g RS from DWG hydrolysis at 45 min with 6% HCl. 1.85 g/L PHB produced by FH12 at 30°C, 6%, after 96 h. NMR and FTIR confirmed the authentic chemical structure of PHB. PHB showed thermal stability from 270°C to 340°C with max loss at 350°C. PHB showed UV‐blocking and crystalline structure for packaging use.

Fed-batch production and characterization of polyhydroxybutyrate by Bacillus megaterium LVN01 from residual glycerol

Dyna, 2020
The operating conditions of polyhydroxybutyrate (PHB) production processes are among the factors that most influence yields. In this study, we evaluated PHB production synthesized by Bacillus megaterium LVN01.

Orthopedic implant of a polyhydroxybutyrate (PHB) and hydroxyapatite composite in cats

Journal of Feline Medicine and Surgery, 2011
The purpose of this study was to evaluate the tissue response to a 70% polyhydroxybutyrate and 30% hydroxyapatite composite in the form of a bone implant, placed intracortically in the distal metaphyseal of the right femur, and subcutaneous implants in cats. Samples of the composite were implanted subcutaneously in the dorsolumbar region and the distal

Polyhydroxybutyrate as a Prebiotic: Mechanisms of Action, Optimization of Fermentation Production, and Food Application [PDF]

Shipin Kexue
Polyhydroxybutyrate (PHB) is an important lipophilic carbon-based energy storage polymer in microbial cells. It is biodegradable and biocompatible, serving as a new type of prebiotic, also known as a “ketogenic substance”.

Telechelic Polyhydroxyalkanoates/Polyhydroxybutyrates (PHAs/PHBs)

, 2017
Poly(3-hydroxyalkanoate)s, PHAs, are natural polyesters collected as intracellular granules as a result of a metabolic stress upon unbalanced growth, owing to a limited supply of a necessary nutrient and to the presence of an excess of a carbon source [1,2,3,4,5,6,7-8]. PHAs have material properties ranging from rigid and highly crystalline to elastic,

Mechanistic Insight with HBCH2CoA as a Probe to Polyhydroxybutyrate (PHB) Synthases

ACS Chemical Biology, 2014
Abstract Polyhydroxybutyrate (PHB) synthases catalyze the polymerization of 3-(R)-hydroxybutyrate coenzyme A (HBCoA) to produce polyoxoesters of 1–2 MDa. A substrate analogue HBCH2CoA, in which the S in HBCoA is replaced with a CH2 group, was synthesized in 13 steps using a chemoenzymatic approach in a 7.5% overall yield.

Green-in-green biohybrids as transient biotriboelectric nanogenerators

iScience, 2022
Summary: Green self-powered devices based on biodegradable materials have attracted widespread attention. Here, we propose the construction of the transient biotriboelectric nanogenerator (TENG) using green-in-green bionanocompoites.
