Stable and Robust Dissolved Oxygen Control for the Fermentative Process of Bt δ - Endotoxin Production
نویسندگان
چکیده
−− This paper proposes a robustness analysis for a dissolved oxygen controller based on Lyapunov theory. The control strategy is designed for the Bacillus thuringiensis δ-endotoxins production process. First, the control strategy is presented and second, it is considered with a biomass estimator in closed loop and it is shown a robustness analysis for the errors introduced by both: biomass estimation and modeling errors. Simulation results with real experimental data are included in order to discuss the controller performance. Keywords−− Dissolved Oxygen Control; Lyapunov Theory; Bacillus thuringiensis; Biotechnological Process; Biomass Estimation.

Checking the Sensitivity of Solute Advection- Dispersion Model to Reaction Coefficients and River Hydraulic Properties in the Process of Dissolved Oxygen Simulation
Nowadays, environmental pollutions especially water pollution is increasingly developing. One of the problems of entering the pollutants to rivers is reduction in the concentration of river dissolved oxygen. In order to manage the water resources, amount of dissolved oxygen should be predicted. This study presents a novel equation for simulating the concentration of river dissolved oxygen by ad...
متن کاملEffects of Protoplast Fusion on δ-endotoxin Production in Bacillus thuringiensis Spp. (H14)
In this study, mutant forms of Bacillus thuringiensis spp. israelensis (H14) were produced. These mutants were identified when the cells were cultured on chloramphenicol plates and stained with crystal violet. Protoplasts of the mutants were isolated by enzymatic digestion (lysozyme) of the cell walls at the presence of an osmotic stabilizer. The protoplasts were induced to fuse to each other i...
متن کاملAn Overview on the Crystal Toxins from Bacillus thuringiensis
Strains of Bacillus thuringiensis (Bt) are known to produce crystalline proteins (δ-endotoxins) concomitantly with sporulation during their stationary phase of growth, which are demonstrated as lethal to lepidopeterous, coleopeterous and dipterous insects in addition to mites, nematodes, protozoa and flukes. Upon ingestion, the δ-nascent endotoxin is an inactive protoxin complex of (Cry alone o...
متن کاملProduction of marker-free transgenic Jatropha curcas expressing hybrid Bacillus thuringiensis δ-endotoxin Cry1Ab/1Ac for resistance to larvae of tortrix moth (Archips micaceanus)
BACKGROUND The potential biofuel plant Jatropha curcas L. is affected by larvae of Archips micaceanus (Walker), a moth of the family Tortricidae. The hybrid Bacillus thuringiensis (Bt) δ-endotoxin protein Cry1Ab/1Ac confers resistance to lepidopteran insects in transgenic rice. RESULTS Here, we report the production of a marker-free transgenic line of J. curcas (L10) expressing Cry1Ab/1Ac usi...

Partial nitrification was reported to be technically feasible and economically favorable, especially for wastewaterwith high ammonium concentration or low C/N ratio. In this study, the effect of dissolved oxygen (DO)and influent ratio of chemical oxygen demand to nitrogen (COD/N) ratio on biological nitrogen removal fromsynthetic wastewater was investigated. Experiments were c...
