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.

Microstructure and Properties of Polyhydroxybutyrate-Chitosan-Nanohydroxyapatite Composite Scaffolds
The Scientific World Journal, 2012 Polyhydroxybutyrate-chitosan-hydroxyapatite (PHB-CHT-HAP) composite scaffolds were prepared by the precipitation of biopolymer-nanohydroxyapatite suspensions and following lyophilisation.

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

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 ...

Nepal Journal of Biotechnology, 2019 Polyhydroxybutyrates (PHBs) are energy reserves synthesized by different micro-organisms such as Alcaligenes, Pseudomonas, Staphylococcus, Algae, in excess of carbon and limitation of nutrients like nitrogen. These biopolymers are suitable alternate to synthetic carbon-based polymers.

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

ISOLATION AND CHARACTERIZATION OF POLYHYDROXYBUTYRATE (PHB) PRODUCING NOVEL BACTERIA Pseudomonas canadensis BY USING TAPIOCA POWDER AS NUTRIENT SOURCE [PDF]
, 2021 Polyhydroxybutyrate (PHB) is a synthesized bacterial macromolecule. PHB are chosen as alternatives for the development of biodegradable plastics, due to their rapid degradability under natural environmental conditions.

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.
