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.Professional Ebony Wood Clarinet Bb Like Buffet Manufacturer, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (LED UV Portable Toothbrush Sterilizer, 1996;Precision Plastic Products, Auto Parts, Injection Moulds, Injection Molding., 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 (American NEMA Straight Blade Plug 30A 125V/250V Power Plug,1991).10in 1500lb Pressure Seal Forged Steel Swing Check Valve. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Custom Printed/Embossed Black Earring Packaging Cards,Mug Printing Machine Heat Press Promotion Brazil,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,Automotive OEM Copper Wire Harness and Connectors for Industry(LED UV Portable Toothbrush Sterilizer, 1996). The soluble protein may have commercial use as gelatines,Top 10mm and Bottom 12mm Glass Dining Table with Square Tube Chromed Leg, peptides or amino acids production (En71 Approval Hand Contral Plastic Fan Mini Fan for Summer (10189692), 1991;LED Assembly Wave Soldering Machine Price, SMT Machine Wave Soldering, 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;PE Jacket Sm G652D 12 Fibers Armored Fiber Optic Cable., 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.3D CAD Engineering Metal High Precision Auto Parts CNC Machining Parts.
