Modeling and Simulation of Polyhydroxybutyrate Production by Protomonas extorquens in Fed-batch Culture
Modeling and simulation of Polyhydroxybutyrate (PHB) production by Protomonas extorquens in fed-batch culture were conducted in this research. The fed-batch model, developed for this process, employed a kinetic model proposed by other researchers. Several kinetic models were investigated to choose the best model. The criterion for this selection was goodness of fit (δ2). Haldane kinetic model w...
متن کاملComparison between batch and fed-batch production of rhamnolipid by Pseudomonas aeruginosa
This paper presents a comparison between batch and three different sets of fed batch fermentations forrhamnolipid production by Pseudomonas aeruginosa. The batch run was performed with 500 ml of culturemedium having the initial glycerol and sodium nitrate concentrations of 30 and 8.3 g/l, respectively. For a fedbatch run with nitrogen source in feed, 250 ml of the nitrogen exc...
متن کاملPhytase production by the unconventional yeast Pichia anomala in fed batch and cyclic fed batch fermentations
A marked enhancement in the production of cell-bound phytase in Pichia anomala was achieved in cyclic fed batch fermentation (47333 UL -1 ) in comparison with that in batch (11569 UL -1 ) and fixed volume fed batch (36911 UL -1 ) fermentations in cane molasses medium. Phytase productivity was sustainable in cyclic fed batch fermentation over seven days, and therefore, this mode of fed batch fer...
متن کاملBioprocess optimization of Xanthan production by Xanthomonas campestris using semi-defined medium in batch and fed-batch culture
Xanthan gum is an extracellular hetero polysaccharides of many industrial applications and produced by Xanthomonas campestris. This biopolymer is produced as extracellular product in submerged fermentation system. The production of xanthan was influenced by the concentration in glucose in medium. The maximal volumetric production of 17.9 g L was obtained in 80 g L glucose culture in shake flask...
متن کاملBaker’s yeast production under fed batch culture from apple pomace
Apple pomace extract (APE) in aerobic variable fed batch culture under standardized fermentation parameters was evaluated for the production of baker’s yeast. The substrate was fed at a flow rate of 0.39 dm h to regulate fermentable sugar concentration between 1-2 % in bioreactor. An average specific growth rate of 0.24 h and cellular yield coefficient of 0.48 g/g sugar was obtained during bake...
