A Hidden Projection Property of Plackett - Burman and Related Designs
Box and Hunter (1961) made an important observation that any fractional factorial design of resolutionR has the property that when projected onto anyR 1 factors it becomes a full factorial design. This has a signi cant implication for statistical analysis. We observe that the Plackett-Burman and related designs have a hidden projection property with an analogous implication for the analysis. Be...
متن کاملOptimization of methylene blue removal by stable emulsified liquid membrane using Plackett–Burman and Box–Behnken designs of experiments
The stability of an emulsified liquid membrane composed of Span80 as a surfactant, D2EHPA as an extractant and sulfuric acid as an internal phase was first studied according to different diluents and many operating parameters using the Plackett-Burman design of experiments. Then the removal of methylene blue from an aqueous solution has been carried out using this emulsified liquid membrane at ...
متن کاملOptimization of Reduced Glutathione Production by a Lactobacillus plantarum Isolate Using Plackett–Burman and Box–Behnken Designs
In this work, we aim to optimize the production of reduced glutathione (GSH) synthesized intracellularly by a food-grade microorganism through a statistical approach. Using a colorimetric method, 25 Lactobacillus plantarum isolates were screened in an attempt to find a GSH-producing strain. It was found that 36% of the tested isolates showed positive result. Isolate (L7) was found to produce 15...
متن کاملOptimization of Chitinase Production by Bacillus pumilus Using Plackett-Burman Design and Response Surface Methodology
A soil bacterium capable of degrading chitin on chitin agar plates was isolated and identified as Bacillus pumilus isolate U5 on the basis of 16S rDNA sequence analysis. In order to optimize culture conditions for chitinase production by this bacterium, a two step approach was employed. First, the effects of several medium components were studied using the Plackett-Burman design. Among various ...
متن کاملNutritional Requirements of Bacillus thuringiensis During Different Phases of Growth, Sporulation and Germination Evaluated by Plackett-Burman Method
The effects of different sources of carbon, nitrogen and some of trace elements on cultivation of Bacillus thuringiensis H14 were studied. Glucose, glycerol, sodium acetate, (NH4)2SO4, corn steep liquor, yeast extract, hydrolyzed casein, Ca2+, Mg2+ and Mn2+ were the main parameters evaluated by Plackett-Burman statistical method. All el...
