Application of the Taguchi Design for Production of Poly(β-hydroxybutyrate) by Ralstonia eutropha
The Taguchi design of experiments was used to test the relative importance of medium components and environmental factors on poly(β-hydroxybutyrate)(PHB) production by Ralstonia eutropha. The optimum condition was obtained as: fructose concentration, 15 g/L; C/N ratio, 7.4; agitation speed 200 rpm; culture time, 40 h; temperature, 25 ° C; seed age, 15 h. At optimu...
متن کاملIsolation and Optimization of Poly Β Hydroxybutyrate Producing Cyanobacterial Strains
Cyanobacteria have many unexploited potential for natural products with a huge variability in structure and biological activity. Under stress conditions they are reported to produce biopolymers like poly-β-hydroxybutyrate (PHB), which can be produced intracellularly.Cyanobacteria are capable of synthesizing small amount of poly-β-hydroxybutyrate (PHB) under nitrogen and phosphorous starvation c...
متن کاملImmunostimulatory and growth-promoting potential of poly-β-hydroxybutyrate in rainbow trout (Oncorhynchus mykiss) fingerlings culture
In the current study, the effect of dietary supplementation of poly-β-hydroxybutyrate (PHB) on growth performance, digestive enzymes activity, body composition, non-specific immune response and diseases resistance of rainbow trout fingerlings were investigated. Five hundred and fifty-two healthy fingerlings (8.2±1.0 g) were randomly distributed in 12 tanks (150 L) at a density of 46 fish/ tank ...
متن کاملPoly-β-hydroxybutyrate Production by Methylosinus trichosporium OB3b at Different Gas-phase Conditions
Background: The utilization of methane for production of Poly-β-hydroxybutyrate (PHB) not only cuts the emissions of greenhouse gases but also greatly reduces PHB production cost. Objectives: The aim of this study was to determine the effects of gas-phase conditions on PHB production by Methylosinus trichosporium OB3b. Ma...
متن کاملRole of β-hydroxybutyrate, its polymer poly-β-hydroxybutyrate and inorganic polyphosphate in mammalian health and disease
We provide a comprehensive review of the role of β-hydroxybutyrate (β-OHB), its linear polymer poly-β-hydroxybutyrate (PHB), and inorganic polyphosphate (polyP) in mammalian health and disease. β-OHB is a metabolic intermediate that constitutes 70% of ketone bodies produced during ketosis. Although ketosis has been generally considered as an unfavorable pathological state (e.g., diabetic ketoac...
