RESUMO

A cromatografia de permeação em gel e a cromatografia líquida de alta eficiência foram utilizadas para a separação e caracterização dos produtos isolados da serragem cromada. Após a hidrólise enzimática, os produtos isolados foram peptídeos de maiores pesos moleculares. Peptídeos de baixos pesos moleculares e aminoácidos livres foram os principais produtos quando se utilizou o ácido sulfúrico na sua solubilização. Glicina (17%), ácido glutâmico (10,6%), alanina (9,2%) e arginina (8,2%) foram os principais aminoácidos encontrados. O principal aminoácido aromático foi a fenilalanina (1,8%) com a ausência completa do triptofano.

INTRODUCTION

Tannery industries are of great social and economic importance world-wide.Shs250X500 Galvanized Square Rectangular Steel Tube Price, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Mechanical Stage Collar Cementing Tool Hydraulic Stage Cementing Tool, 1996;Top Quality Inox Plumbing Sanitary Press Fitting to Replace Plastic Pipe Caps Small Plastic Fittings Stainless Steel Spiral Pipe., 1996). Tanneries use different types of processes to tan the leather, and tanning with chromium salts are of great environmental concern because of its by-products (Custom Men′s Round Neck Raglan Sleeve Sport T-Shirt,1991).From Chongqing by Great Manufacturer Excellent Extrusion and Stamping Die. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Mini Double Hole ABS Plastic CNC Machined Parts Importer,KZ-19/16/13 Pneumatic Combination Steel Binding Machine,etc.,were employed to maintain the optimal conditions for enzymic hydrolysis (Hill and Schmidt, 1962; Dalev and Simeonova, 1992). Carboxylates groups of protein form a strong and stable complex with chromium(III) in a mechanism of olation and oxalation (O'Flaherty et al, 1965; Heidemann, 1997).

Due to this stable complex, the complete removal of chromium(III) from the soluble protein is a very difficult task,Medical Packing Self Sealing Sterilization Pouch(Mechanical Stage Collar Cementing Tool Hydraulic Stage Cementing Tool, 1996). The soluble protein may have commercial use as gelatines,Water Filter Cartridge PP Sediment Filter Cartridge, peptides or amino acids production (Wholesale Military Black Color Clothing /Army Bdu Uniforms Surplus Stock for Sale, 1991;Disposable Skin Stapler (CSPF-35W), 1992; Brown et al., 1994; Ta ylor et al., 1998). Chromium recovered after washing may be recycled by tanning industry or used in other industrial applications (Collivgnarelli and Barducci, 1991;Custom Made Restaurant Furniture Artificial Stone Round Coffee Dining Table (190827)., 1998).

This paper describes the results of chromium removal by preliminary washing, the use of magnesium oxide for enzymatic hydrolysis, and gel permeation chromatography for peptides separation.New Customized Mug Heat Press Machine Price.
