batch culture of ralstonia eutropha using the recycled gas closed circuit culture system was conducted in order to develop a practical fermentation system for industrial autotrophic culture for poly (hydroxybutrate) production. the gas phase of the culture system consisted of substrate gas so that gases in this culture could be recycled as long as the amount of the gas consumed would be repleni...
Draft genome sequence of Thalassobius mediterraneus CECT 5383T, a poly-beta-hydroxybutyrate producer
Thalassobius mediterraneus is the type species of the genus Thalassobius and a member of the Roseobacter clade, an abundant representative of marine bacteria. T. mediterraneus XSM19(T) (= CECT 5383(T)) was isolated from the Western Mediterranean coast near Valencia (Spain) in 1989. We present here the draft genome sequence and annotation of this strain (ENA/DDBJ/NCBI accession number CYSF000000...
BACKGROUND Poly(4-hydroxybutyrate) [poly(4HB)] is a strong thermoplastic biomaterial with remarkable mechanical properties, biocompatibility and biodegradability. However, it is generally synthesized when 4-hydroxybutyrate (4HB) structurally related substrates such as γ-butyrolactone, 4-hydroxybutyrate or 1,4-butanediol (1,4-BD) are provided as precursor which are much more expensive than gluco...
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...
