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...

background: cellulytic enzymes including carboxymethyl cellulases play the key role in hydrolysis of cellulose, a huge organic carbon reservoir on earth, into monomeric sugars and their eventual conversion into valuable chemicals and energy sources. objectives: in this study, we described the identification of a basidiomycete isolate ndvn01 and optimization of culture conditions and medium comp...

phospholipids are important for the biological lipid and are commonly used in biophysical studies.a quantumcalculation for two phospholipids dipalmitoylphosphatidylethanolamine and dipalmitoylphosphatidic acidwere performed using the abinitio software. geometry optimization structures were obtained at rhf level using3-21g, 6-31g*. these basis sets were used to understanding the effects of envir...

cyanobacteria have been considered due to producuction of types of secondary metabolites and antimicrobial compounds. this research designated for optimization of bg11 culture medium to increase the antifungal activity of cyanobacterium sp. pgu1 against the plant pathogenic fungi, fusarium oxysporum f. sp lycopersici and rhizoctonia solaniag2-2-iiib. cyanobacterium was isolated from the persian...

multistage stochastic programming is a key technology for making decisions over time in an uncertain environment. one of the promising areas in which this technology is implementable, is medium term planning of electricity production and trading where decision makers are typically faced with uncertain parameters (such as future demands and market prices) that can be described by stochastic proc...
