Application of the Response Surface Methodology for the Optimization of the Aqueous Enzymatic Extraction of Pistacia Khinjuk Oil
ABSTRACT: Aqueous enzymatic extraction of oil from pistacia khinjuk was performed using cellulase. The central composite design was used to optimize the parameters that are significant to the process. The influence of three regressors on the percentage of oil recovery from seed was evaluated using second-order polynomial multiple regression model. Analysis of variance showed a high coefficient ...
متن کاملScreening and Optimization of Microextraction of Pb(II) by Inductively Coupled Plasma-Atomic Emission Using Response Surface Methodology
Dispersive liquid–liquid microextraction (DLLME) combined with inductively coupled plasma-atomic emission spectrometry (ICP-AES) was applied for the determination of lead in different environmental water samples. Ammonium pyrrolidine dithiocarbamate (APDC), chloroform and ethanol were used as chelating agent, extraction solvent and disperser solvent, respectively. The effective parameters, such...
متن کاملProcess optimization for ethanol production from very high gravity (VHG) finger millet medium using response surface methodology
The Box-Wilson central composite design (CCD) based on response surface methodology (RSM) was used for ethanol fermentation using very high gravity (VHG) finger millet hydrolysate. Optimized process variables were namely, concentrations of yeast extract, magnesium sulphate and pH of the medium. High gravity mashes (>300 g dissolved solids per liter) were prepared by a thermo-stable α-amylase, f...
متن کاملOptimization of biocatalytic synthesis of Chitosan Ester using response surface methodology
Esterification of chitosan with adipic acid catalyzed by immobilized Candida antarctica lipase B was carried out in this study. Response surface methodology (RSM) based on a four-factor- five-level small central composite design (SCCD) was employed to model and analyze the reaction. A total of 21 experiments representing different combinations of the four reaction parameters including ch...
متن کاملProduction of L-Asparaginase by Serratia marcescens SB08: Optimization by Response Surface Methodology
This paper describes optimization method that combines the Plackett-Burman design, a factorial design and the response surface method, which were used to optimize the medium for the production of L-asparaginase by Serratia marcescens SB08. Four medium factors, from out of 11 medium factors, were screened by Plackett-Burman design experiments and subsequent optimization process to find out the o...
