Jun 06, 2012 · Covalent binding. Covalent association of enzymes to supports occurs owing to their side chain amino acids like arginine, aspartic acid, histidine and degree of reactivity based on different functional groups like imidazole, indolyl, phenolic hydroxyl, etc. (D’Souza 1998; Singh 2009).Peptide-modified surfaces when used for enzyme linkage results in higher specific …

Ion exchange chromatography resins are composed of positively or negatively charged functional groups that are covalently bound to a solid matrix. Common matrices are cellulose, agarose, polymethacrylate, polystyrene, and polyacrylamide. The latter three matrices allow higher flow rates. Several factors inform resin choice:

Particle Size: Individual solid particle in a soil can have different sizes and this characteristic of soil can have a significant effect on its engineering properties. Size of particles that constitute soils may vary from boulders to that of large molecules. The soil particles coarser than 0.075 mm constitute the coarse fraction of soils.

Although biochemical analysis requires disruption of the anatomy of the cell, gentle fractionation techniques have been devised to separate the various cell components while preserving their individual functions. Just as a tissue can be separated into its living constituent cell types, so the cell can be separated into its functioning organelles and macromolecules.

Drive takes the form of either double unbalance gear units (type BHG), circular-motion vibrating drives (type BV) or unbalance motors (type BHR). The SIEBTECHNIK banana screening machine achieves good separating accuracy at an extremely high feed rate and with difficult-to-screen material. Its operational behaviour makes it a high-speed screen.

Settling velocity of individual particles depends on particle diameter; Forces acting on soil particle are gravitation, buoyancy and drag forces, and all depend on particle size; The larger particles settle first à Stokes law Since soils are a mixture of different size particles, soil’s are classified using the so-called soil textural triangle.
