Piriformospora indica, a member of basidiomycota is an axenically cultivable endophytic fungus which exerts plant growth promoting effects on its host plant. P. indica is known to produce α-amylase and protease. Since the organism exhibits beneficial role in plant growth promotion, achieving high biomass is immensely essential. Hence to enable the commercial production, screening of medium comp...

This paper describes and discusses a Plackett-Burman experiment aimed at increasing supermarket sales of a top-selling national magazine. The experiment involved 10 factors relating to in-store advertising and the location of the magazine within the store. We discuss issues including choice of factors, alternative designs, sample-size determination (number of test stores and the length of the t...

R.Bęczkowski, Institute of Mechanical Technology, Czestochowa University of Technology, Poland Hardness is one of the components responsible for the resistance to wear. The development of new materials with hardness surface more than 65 HRC is possible with use welding technologies. High chromium cored wires belong to welding materials that are often used to cladding to protect surface. This ar...

Many Trichoderma species are able to produce 6-pentyl-α-pyrone (6-PP), a lactone with coconut-like aroma. In the present work, several culture parameters were studied to enhance the production of 6-PP by Trichoderma harzianum 4040 in solid-state fermentation. Green coir powder added to a nutrient solution was used as support material for fermentation. A Plackett-Burman screening technique was a...

The main effects of six experimental factors on the efficiency of HS (headspace) extraction in headspace gas chromatography--flame ionization detector (HS-GC-FID) determination of twenty organic solvents routinely used in production of pharmaceuticals were obtained on the basis of the results of experiments carried out according to the Plackett-Burman factorial design. The effects were used as ...

DNJ, an inhibitor of α-glucosidase, is used to suppress the elevation of postprandial hyperglycemia. In this study, we focus on screening an appropriate microorganism for performing fermentation to improve DNJ content in mulberry leaf. Results showed that Ganoderma lucidum was selected from 8 species and shown to be the most effective in improvement of DNJ production from mulberry leaves throug...

Genome-scale metabolic models embody a significant advantage of systems biology since their applications as metabolic flux simulation models enable predictions for the production of industrially-interesting metabolites. The biotechnological production of lycopene from Yarrowia lipolytica is an emerging scope that has not been fully scrutinized, especially for what concerns cultivation condition...

potassium chloride (kcl) is a highly water soluble substance which is usually used to prevent hypokalemia. oil in water disperse phase encapsulation method was used to prepare kcl loaded microcapsules using beeswax and carnauba wax as a hydrophobic matrix. the morphology and characteristics of kcl loaded microspheres were studied using scanning electron microscopy (sem), photon correlation spec...

In this work, a clean and simple magnetic solid-phase microextraction based on L-arginine modified dialdehyde starch nanocomposite was developed for the preconcentration determination of diclofenac in biological samples by UV–Vis Spectrophotometry. A Plackett–Burman experimental design used to evaluate influence effective parameters. Significant parameters were further optimized Central Composi...
