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 کاملOptimization of Lipase Production Medium for a Bacterial Isolate
Lipases are versatile biocatalysts that are used extensively in detergent and pharmaceutical formulations. Lipases have an immense potential for being employed as industrial catalysts for production of fine chemicals. Their superior value arises from specificity and efficacy as compared to chemical catalysts. However new lipases with properties amenable for application in specific industrial pr...
متن کاملMultiple propionyl coenzyme A-supplying pathways for production of the bioplastic poly(3-hydroxybutyrate-co-3-hydroxyvalerate) in Haloferax mediterranei.
Haloferax mediterranei is able to accumulate the bioplastic poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) with more than 10 mol% 3-hydroxyvalerate (3HV) from unrelated carbon sources. However, the pathways that produce propionyl coenzyme A (propionyl-CoA), an important precursor of 3HV monomer, have not yet been determined. Bioinformatic analysis of H. mediterranei genome indicated that t...
متن کاملTwo-stage (photoautotrophy and heterotrophy) cultivation enables efficient production of bioplastic poly-3-hydroxybutyrate in auto-sedimenting cyanobacterium
Sustainable production of bioplastics by heterotrophic microbes has been restricted by the limited resources of organic substrates and the energy required for biomass harvest. Here, the easy-to-harvest cyanobacterium (Chlorogloea fritschii TISTR 8527), from which the biomass instantaneously settled to the bottom of liquid culture, was utilized to produce poly-3-hydroxybutyrate (PHB) using a two...
متن کاملisolation and identification of poly β-hydroxybutyrate over-producing bacteria and optimization of production medium
conclusions the results suggest that b. coagulans is a good candidate for the fermentative production of phb. background biodegradable polyesters are candidates for the development of environmental friendly plastics. poly-β-hydroxybutyrate (phb) is a type of polyester from the hydroxyalkanoates family, synthesized by bacteria as an intracellular material and accumulated as granules in the cytop...
