Poly[(R)-3-hydroxybutyrate] production under different salinity conditions by a novel Bacillus megaterium strain.
Bacillus megaterium uyuni S29, isolated from the Bolivian salt lake Uyuni, displays a high capability to produce poly[(R)-3-hydroxybutyrate] (PHB) in industrial culture media. In order to analyze the influence of salt on biomass formation and PHB production, cultivations at different NaCl concentrations were carried out according to the salinity conditions of the habitats of the strain's origin...
متن کاملOptimization of cyclodextrin production from sago starch.
Cyclodextrin (CD) is synthesized by bacterial cyclodextrin glycosyltransferase (CGTase) and is widely used in food, pharmaceutical, cosmetic, and agricultural industries. In this study, Bacillus circulans CGTase was partially purified by ammonium sulfate precipitation at 50-70% saturation. The optimum pH and temperature for CD production from sago starch were found to be in the ranges of 4.5-5....
متن کاملProduction of Short Chain Length Polyhydroxyalkanoates by Bacillus megaterium PHB29 from Starch Feed Stock
Polyhydroxyalkanoates (PHAs) are polyoxoesters of R-hydroxyalkanoic acid monomers accumulated in bacterial cytoplasm as granules when carbon sources are available in excess and other nutrients such as nitrogen and phosphorus are limited in their surroundings (Dawes and Senior, 1972; Lee et al., 1999). They act as carbonenergy reserves and also as electron sinks, which enhance the fitness of the...
متن کاملApplication 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 کاملBiosynthesis of poly(3-hydroxybutyrate) (PHB) by Cupriavidus necator H16 from jatropha oil as carbon source.
Poly(3-hydroxybutyrate) (PHB) is a biodegradable polymer that can be synthesized through bacterial fermentation. In this study, Cupriavidus necator H16 is used to synthesize PHB by using Jatropha oil as its sole carbon source. Different variables mainly jatropha oil and urea concentrations, and agitation rate were investigated to determine the optimum condition for microbial fermentation in bat...
