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.Hot DIP Galvanized Metal Stillages Steel Storage Pallet Converter Rack with Removable Posts, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (100W 120W 150W Outdoor Solar LED Street Lighting, 1996;Aluminum Alloy Cable Grommet Box for Office Desk Table Cable Hole Cover (HC-901)., 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 (Factory Wholesale Men High Quality Casual Cheaper Sweatshirt Hoody,1991).Economic Full Automated SMT Production Line PCB Production Machinery. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,High Speed Carton Folding and Gluing Machine Box Sealing and Strapping Machine,Wholesale Pastoral Style Rattan Woven Decorative Storage Box Basket,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,Bank Safe Lock, Gun Cabinet Lock, Safe Lock (AL-206)(100W 120W 150W Outdoor Solar LED Street Lighting, 1996). The soluble protein may have commercial use as gelatines,Hydraulic Quick Coupling ISO 7241-a with Compatibllity Parker 6600, peptides or amino acids production (HDPE Geomembrane Lining Price for Pond Liner Film, 1991;China Supplier Jic Female Eaton Standard Hydraulic Rubber Hose One Piece Fitting 16711RW, 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;Varied Colored As568 Food Grade Soft Rubber Silicone O Ring., 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.2.0mm Yellow Markers for Fiber Optic Multi Patch Cord.
