Immobilized enzyme

composite has been investigated. For that purpose, the PMMA samples with Al2O3 additive prepared with different percentages(0,15,25,35 and 45) wt.% and different thickness. The experimental results showed that the D.C electrical conductivity increased with increasing the alumina concentrations and temperature. Also the activation energy change with increasing of additional alumina. The dielectric constant, dielectric loss, A.C electrical conductivity are changed with change the concentration of…

Lipids are fatty acids and their derivatives, and substances related biosynthetically or functionally to these compounds. Lipids are diverse group of organic compounds including fats, oils, hormones, and certain components of membranes that are grouped together and mainly amphipathic. The variation in head groups and aliphatic chains allows the presence of more than 1000 different lipid species in any eukaryotic cell. Different types of lipid include Phospholipids, Sphingolipids and Cholesterol…

Burkholderia pseudomallei also called as pseudomonas pseudomallei is an intracellular gram negative bipolar staining aerobic motile shaped rod with a safety pin appearance when seen microscopically measuring 25 micro metre in length and 0.4 -0.8 micro metre in diameter . It is capable of self population using flagella. In vitro , it requires a temperature of 40 degree and grows in an acidic environment fermenting glucose and galactose . It produces both exotoxin and endotoxins. It causes…

3.1. Chemical composition and monosaccharide analysis Polysaccharide molecules are linked together by water molecules through hydrogen bonds in an aqueous solution. Adding ethanol into aqueous solution of polysaccharide initially dehydrate polysaccharides, enhance intra-molecular hydrogen bonding, cause conformational change and aggregation of polysaccharide molecules, and eventually leads to the precipitation of macromolecular chains, and the following addition of alcohol solvent gradually…

The purpose of this study was to investigate the effect of a system that automatically adjusting hydrogen peroxıde Colloıdal-Ag dose to reduce colonization and growth of heterotrophic bacteria in dental unit waterlines and wastewaters. Thirty dental units were assigned into three groups with respect to the protocol employed: Group 1: 10 units were selected for automatic administration. Group 2: 10 units were selected for manual administration and Group 3: 10 units served as controls. Water…

1 enzyme Enzymes are biological catalysts. A protein compound Energy can reduce the carbon reaction. Enzymes to accelerate specific types of reactions. And the kind of substance that reacts. 2.1.1 catalysis of enzymes E is a catalyst (enzyme). S is a precursor called chop, nitrates and substance P is a product. E + S ---------------> E S ---------------> E + P. Complexometry 2.1.2 Factors affecting the enzyme. 1) What type of controlled…

Biodiesel production is usually expressed through the process of trans-esterification reaction. Recently, homogeneous catalysts are broadly preferred for biodiesel production in eminent scale operation. Still, they are toxic, highly flammable and corrosive in nature [1]. Boey et al. analysed the purpose of the waste cockle shell from palm olein oil in biodiesel production of Anadara granosa. At 900 °C the waste shell was calcined for 2 h that mainly compiled of 71% of Ca to develop an active…

Results and Discussion A. Diffusion of selected plant pigments In conducting the diffusion of 4 different kinds of treatments (distilled water, distilled water placed in boiling bath, vegetable oil, heated vegetable oil), the researchers made use of the atsuete and sugar beets. The different kinds of treatments determined how the temperature will affect the color intensity of the atsuete and sugar beets. There were 4 test tubes used in each atsuete and sugar beets with each having a…

FTIR analysis of the stem bark extracts of Cassia fistula has absorption bands and the wave numbers (cm-1) of the prominent peaks obtained were described in Table 2. The peak at a frequency of 3463 cm-1, 1618 cm-1, 1448.3 cm-1 and 1241.9 cm-1 were strong while the others vary from medium to weak. Discussion: Phytochemical studies revealed the presence of secondary metabolites like tannins, flavonoid, carbohydrate, saponins, glycosides and phenol in the leaf extract while tannins, flavonoids,…
