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 optimum condition the yield of phb pr...

Pseudomonas resinovorans produced poly-beta-hydroxyalkanoates (PHAs) when grown on hydrocarbons but not on glucose. In a chemostat culture, the PHA composition was beta-hydroxybutyrate (C4)-beta-hydroxyhexanoate (C6)-beta-hydroxyoctanoate (C8)-beta-hydroxydecanoate (C10) (1:15:75:9) on octanoate and C4-C6-C8-C10 (8:62:23:7) on hexanoic acid. Contrary to the reported behavior of Pseudomonas oleo...

Lundgren, D. G. (Syracuse University, Syracuse, N.Y.), R. Alper, C. Schnaitman and R. H. Marchessault. Characterization of poly-beta-hydroxybutyrate extracted from different bacteria. J. Bacteriol. 89:245-251. 1965.-Poly-beta-hydroxybutyrate (PHB) from different bacterial genera was studied with regard to its crystal structure, infrared absorption, intrinsic viscosity, and electron microscopy. ...

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...
