BACKGROUND Cytochrome P450 monooxygenase constitutes a significant group of oxidative enzymes that can introduce an oxygen atom in a high regio- and stereo-selectivity mode. We used the Bacillus megaterium cytochrome P450 BM3 (CYP450 BM3) and its variants namely mutant 13 (M13) and mutant 15 (M15) for the hydroxylation of diverse class of flavonoids. RESULTS Among 20 flavonoids, maximum seven...

The conversion of biomass into chemicals, fuels and energy using the bio-refinery concept has attracted lot of attention. In particular, lignocellulosic biomass, consisting of cellulose (ca. 50%), hemicellulose (ca. 30%) and lignin (ca. 20%) is of special interest because it is non-edible and in plentiful supply. Hemicellulose is a heterogeneous polymer, made up of C5 and C6 sugars (such as xyl...

Fructose is utilized as a common sweetener in many food industries. Today, a large amount of HFCS (high fructose corn syrup, an equilibrium mixture of glucose and fructose) is produced by glucose isomerase, immobilized enzymes from corn starch. There are a lot of date palms in Iran. Date is a favorable source of carbohydrates, and a suitable source for HFDS (high fructose date syrup) production...

With the evolving needs of today’s manufacturing industries in the area of product development, 3D CAD model has become very important. Often in many situations there is a need to remanufacture a physical part where the CAD data is not available with the manufacturer or is lost because of several reasons. In such cases reverse engineering is found to be an effective and efficient tool. Reverse ...

We analyze a general market for an industry of competing service facilities. Firms differentiate themselves by their price levels and the waiting time their customers experience, as well as different attributes not determined directly through competition. Our model therefore assumes that the expected demand experienced by a given firm may depend on all of the industry’s price levels as well as ...
