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 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...
متن کاملMicrobial degradation of poly(3-hydroxybutyrate) and poly(3-hydroxybutyrate-co-3-hydroxyvalerate) in soils.
The microbial degradation of tensile test pieces made of poly(3-hydroxybutyrate) [P(3HB)] or a copolymer of 90% 3-hydroxybutyric acid and 10% 3-hydroxyvaleric acid was studied in soils incubated at a constant temperature of 15, 28, or 40 degrees C for up to 200 days. In addition, hydrolytic degradation in sterile buffer at temperatures ranging from 4 to 55 degrees C was monitored for 98 days. D...
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 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...
