Development of in silico strategies to photoautotrophically produce poly-β-hydroxybutyrate (PHB) by cyanobacteria
(Elsevier, 2022-03)
Poly(3-hydroxybutyrate) (PHB), a biopolymer similar to polypropylene, is currently produced by heterotrophic bacteria. However, the elevated cost of raw material used as carbon and energy sources are promoting the development ...
PHB-degrading Streptomyces sp. SSM 5670: isolation, characterization and PHB-accumulation
(Drishti Offset, 2014-08)
New microbial bioprospecting has become an important way to find new polyhydroxyalkanoate (PHA) producers and degraders. Poly (3-hydroxybutyrate) (PHB), the best known member of the PHAs, has received much attention because ...
Plant growth-promoting bacterium Pseudomonas fluorescens FR1 secrets a novel type of extracellular polyhydroxybutyrate polymerase involved in abiotic stress response in plants
(Springer, 2018-10)
Objectives: Identification of novel microbial factors contributing to plant protection against abiotic stress. Results: The genome of plant growth-promoting bacterium Pseudomonas fluorescens FR1 contains a short mobile ...
Effect of modified montmorillonite on biodegradable PHB nanocomposites
(Elsevier Science, 2010-02)
Polymer nanocomposites, based on a bacterial biodegradable thermoplastic polyester, poly(hydroxybutyrate) (PHB), and two commercial montmorillonites (MT), Na-M (MT) and 30B-M (organically modified MT), were prepared by ...
Improved fermentation strategies in a bioreactor for enhancing poly(3-hydroxybutyrate) (PHB) production by wild type Cupriavidus necator from fructose
(Elsevier Ltd, 2021-01)
Poly(3-hydroxybutyrate) (PHB) belongs to the family of polyhydroxyalkanoates, biopolymers used for agricultural, industrial, or even medical applications. However, scaling up the production is still an issue due to the ...
New Recombinant Escherichia coli Strain Tailored for the Production of Poly(3-Hydroxybutyrate) from Agroindustrial By-Products
(American Society for Microbiology, 2006-06)
A recombinant E. coli strain (K24K) was constructed and evaluated for poly(3-hydroxybutyrate) (PHB) production from whey and corn steep liquor as main carbon and nitrogen sources. This strain bears the pha biosynthetic ...
Quantification of Bacterial Polyhydroxybutyrate Content by Flow Cytometry
(Bio-Protocol LLC, 2017-12)
We describe here a detailed protocol for the quantification of the intracellular content of polyhydroxybutyrate (PHB) in a population of bacterial cells by flow cytometry, which is based on a consensus of several previously ...
Effect of Natural Glyceryl Tributyrate as Plasticizer and Compatibilizer on the Performance of Bio-Based Polylactic Acid/poly(3-hydroxybutyrate) Blends
(Springer/Plenum Publishers, 2019-07)
Bio-based poly(lactic acid)/poly(3-hydroxybutyrate) (PLA/PHB) films were melt-blended with a natural hydrophobic plasticizer (glyceryl tributyrate, TB) at three different concentrations (10, 15 and 20% by weight per 100 ...
Vinasse: from a residue to a high added value biopolymer
(Springer-v D I Verlag Gmbh, 2021-12-17)
This work aimed to study the feasibility of using vinasse for polyhydroxybutyrate (PHB) production by Bacillus megaterium. To optimize the culture medium, a Box–Behnken design was employed considering carbon (C), nitrogen ...
Regulation of polyhydroxybutyrate accumulation in Sinorhizobium meliloti by the trans-encoded small RNA MmgR
(American Society for Microbiology, 2017-01)
Riboregulation has a major role in the fine-tuning of multiple bacterial processes. Among the RNA players, trans-encoded untranslated small RNAs (sRNAs) regulate complex metabolic networks by tuning expression from multiple ...
